각성은 언제?

요 며칠간 마술같은 성능향상을 보여주는 리눅스 커널 패치(200자 정도)가
화제인데요.

https://patchwork.kernel.org/patch/326472/

2.6.38 커널에 포함이 예정되어 있습니다.

SCRIPT(1)                 BSD General Commands Manual                SCRIPT(1)

NAME
     script - 터미날에서 발생하는 모든 세션을 기록한다.

사용법
     script [-a] [파일]

설명
     Script 명령은 터미날에서 보여지는 모든 내용을 파일에 기록한다.  이것은 쉘에서의 사용
     자와 컴과의 작업 상태를 기록하고, 그것을 다시 살펴 보아야할 경우에 아주 유용하게 쓰인
     다.  또한 파이프 기능을 이용하여 다른 작업을 하고 있으면서이 기록 내용을 인쇄할 수도
     있다.

     파일인자가 있으면, 그 파일에 모든 내용을 기록하고, 없으면, typescript 파일에 기록한
     다.

     옵션:

     -a      새로 기록하는 것이 아니라, 이미 있는 file 에나, typescript 파일에 내용을 덧붙
             힌다.

     script를 마치기 위해서는쉘 종료를 호출하면 된다. (대게 exit, logout, ^D)

     vi(1) 와 같은 터미날의 출력을 사용하는 풀그림의 사용도그대로 기록된다. 이때는 조금 지
     저분하게 보일 것이다.  script 명령은 현재 창, 화면에 대한 내용만 기록한다.  즉, 한 터
     미날의 모든 출력을 그대로 기록한다.

환경변수
     다음은 script에서 사용되는 환경변수들이다:

     SHELL  이 값이 지정되어 있으면, script에서 사용할 쉘로이것을 사용하고, 지정되어 있지
            않으면, /bin/sh로 가정한다.

관련 항목
     csh(1) (사용내역(history) 처리 부분을 참조)

발자취
     script 명령은 3.0BSD 시스템에서 처음 나타났다.

벌레
     script 명령은 앞에서 말했듯이 터미날로 출력되는 모든 것을기록하기 때문에, 각종 특수문
     자(줄바꿈문자, 백스페이스, 안시..)들을그대로 기록한다.

yum(8)                                                                  yum(8)

NAME
       yum - Yellowdog Updater Modified

SYNOPSIS
       yum [options] [command] [package ...]

DESCRIPTION
       yum is an interactive, rpm based, package manager. It can automatically
       perform system updates, including dependancy analysis and obsolete pro-
       cessing  based  on "repository" metadata. It can also perform installa-
       tion of new packages, removal of old packages and  perform  queries  on
       the  installed and/or available packages among many other commands/ser-
       vices (see below). yum is similar to other high level package  managers
       like apt-get and smart.

       While  there  are  some  graphical interfaces directly to the yum code,
       more recent graphical interface development  is  happening  with  Pack-
       ageKit and the gnome-packagekit application.

       command is one of:
        * install package1 [package2] [...]
        * update [package1] [package2] [...]
        * check-update
        * upgrade [package1] [package2] [...]
        * remove | erase package1 [package2] [...]
        * list [...]
        * info [...]
        * provides | whatprovides feature1 [feature2] [...]
        * clean [ packages | headers | metadata | dbcache | all ]
        * makecache
        * groupinstall group1 [group2] [...]
        * groupupdate group1 [group2] [...]
        * grouplist [hidden]
        * groupremove group1 [group2] [...]
        * groupinfo group1 [...]
        * search string1 [string2] [...]
        * shell [filename]
        * resolvedep dep1 [dep2] [...]
        * localinstall rpmfile1 [rpmfile2] [...]
        * localupdate rpmfile1 [rpmfile2] [...]
        * deplist package1 [package2] [...]
        * repolist [all|enabled|disabled]
        * help [command]

       Unless the --help or -h option is given, one of the above commands must
       be present.

       Repository configuration is honored in all operations.

       install
              Is used to install the latest version of a package or  group  of
              packages while ensuring that all dependencies are satisfied.  If
              no package matches the given package name(s), they  are  assumed
              to be a shell glob and any matches are then installed.

       update If  run without any packages, update will update every currently
              installed package.  If one or more packages are  specified,  Yum
              will  only update the listed packages.  While updating packages,
              yum will ensure that all  dependencies  are  satisfied.   If  no
              package  matches  the given package name(s), they are assumed to
              be a shell glob and any matches are then installed.

              If the --obsoletes flag is  present  yum  will  include  package
              obsoletes  in  its  calculations - this makes it better for dis-
              tro-version changes, for example: upgrading from  somelinux  8.0
              to somelinux 9.

       check-update
              Implemented  so  you  could know if your machine had any updates
              that needed to be  applied  without  running  it  interactively.
              Returns exit value of 100 if there are packages available for an
              update. Also returns a list of the pkgs to be  updated  in  list
              format.  Returns  0  if  no  packages  are available for update.
              Returns 1 if an error occured.

       upgrade
              Is the same as the update command with the --obsoletes flag set.
              See update for more details.

       remove or erase
              Are  used  to  remove  the specified packages from the system as
              well as removing any packages which depend on the package  being
              removed.

       list   Is  used  to  list various information about available packages;
              more complete details are available in the List Options  section
              below.

       provides or whatprovides
              Is used to find out which package provides some feature or file.
              Just use a specific name or a file-glob-syntax wildcards to list
              the packages available or installed that provide that feature or
              file.

       search Is used to find any packages matching a string in  the  descrip-
              tion,  summary  and  package  name  fields of an rpm. Useful for
              finding a package you do not know by name but know by some  word
              related to it.

       info   Is  used  to  list  a  description and summary information about
              available packages; takes the same  arguments  as  in  the  List
              Options section below.

       clean  Is  used  to clean up various things which accumulate in the yum
              cache directory over time.  More complete details can  be  found
              in the Clean Options section below.

       makecache
              Is  used  to  download  and make usable all the metadata for the
              currently enabled yum repos.

       groupinstall
              Is used to install all of the individual packages in a group, of
              the  specified types (this works as if you'd taken each of those
              package names and put them  on  the  command  line  for  a  "yum
              install" command).
               The  group_package_types  configuration  option specifies which
              types will be installed.

       groupupdate
              Is just an alias for groupinstall, which will do the right thing
              because  "yum  install  X" and "yum update X" do the same thing,
              when X is already installed.

       grouplist
              Is used to list the available groups from all yum repos.  Groups
              are   marked  as  "installed"  if  all  mandatory  packages  are
              installed, or if a group doesn't  have  any  mandatory  packages
              then  it  is installed if any of the optional or default package
              are installed.  The optional "hidden" argument  will  also  list
              groups marked as not being "user visible".

       groupremove
              Is  used  to  remove  all  of  the  pacakges  in a group, unlike
              "groupinstall"  this  will  remove  everything   regardless   of
              group_package_types.  It is worth pointing out that packages can
              be in more than one group, so "groupinstall  X  Y"  followed  by
              "groupremove  Y"  does  not  do  give  you  the  same  result as
              "groupinstall X".

       groupinfo
              Is used to give the description and package list of a group (and
              which  type those packages are marked as). Note that you can use
              the yum-filter-data and yum-list-data  plugins  to  get/use  the
              data  the  other  way  around (Ie. what groups own packages need
              updating).

       shell  Is used to enter the 'yum shell', when a filename  is  specified
              the  contents  of  that  file is executed in yum shell mode. See
              yum-shell(8) for more info

       resolvedep
              Is used to list packages providing the  specified  dependencies,
              at most one package is listed per dependency.

       localinstall
              Is  used  to  install  a set of local rpm files. If required the
              enabled repositories will be used to resolve dependencies.

       localupdate
              Is used to update the system by specifying local rpm files. Only
              the  specified  rpm  files  of which an older version is already
              installed will be installed, the  remaining  specified  packages
              will  be  ignored.  If required the enabled repositories will be
              used to resolve dependencies.

       deplist
              Produces a list of all dependencies and  what  packages  provide
              those dependencies for the given packages.

       repolist
              Produces  a  list  of configured repositories. The default is to
              list all enabled repositories.

       help   Produces help, either for all commands or  if  given  a  command
              name then the help for that particular command.

GENERAL OPTIONS
       Most  command  line  options can be set using the configuration file as
       well and the descriptions indicate the necessary  configuration  option
       to set.

       -h, --help

       -c [config file]
              Specifies the config file location - can take http, ftp urls and
              local file paths.

       -q, --quiet

              means print more errors (if any) -e 0 is good for cron jobs.
              Configuration Option: errorlevel

       -R [time in minutes]
              Sets  the maximum amount of time yum will wait before performing
              a command - it randomizes over the time.

       -C     Tells yum to run entirely from cache  -  does  not  download  or
              update  any  headers  unless  it has to to perform the requested
              action.

       --version
              Reports the yum version number and exits.

       --showduplicates
              Doesn't limit packages to their latest  versions  in  the  info,

              abled in the configuration file using the enabled=0 option.
              Configuration Option: enabled

       --disablerepo=repoidglob
              Disables specific repositories by id or glob.
              Configuration Option: enabled

       --obsoletes
              This option only has affect for  an  update,  it  enables  yum?s

              command above.
              Configuration Option: obsoletes

       -x, --exclude=package
              Exclude a specific package by name or glob from updates  on  all
              repositories.  Configuration Option: exclude

       --disableexcludes=[all|main|repoid]
              Disable  the excludes defined in your config files. Takes one of
              three options:

       -t, --tolerant
              This option currently does nothing.

LIST OPTIONS
       The following are the ways which you can invoke yum in list mode.  Note
       that  all list commands include information on the version of the pack-
       age.

       yum list [all | glob_exp1] [glob_exp2] [...]
              List all available and installed packages.

       yum list available [glob_exp1] [...]
              List all packages  in  the  yum  repositories  available  to  be
              installed.

       yum list updates [glob_exp1] [...]
              List  all  packages  with updates available in the yum reposito-
              ries.

       yum list installed [glob_exp1] [...]
              List the packages specified by args.  If an  argument  does  not
              match  the  name  of an available package, it is assumed to be a
              shell-style glob and any matches are printed.

       yum list extras [glob_exp1] [...]
              List the packages installed on the system that are not available
              in any yum repository listed in the config file.

       yum list obsoletes [glob_exp1] [...]
              List  the packages installed on the system that are obsoleted by
              packages in any yum repository listed in the config file.

       yum list recent
              List packages recently added into the repositories.

       Specifying package names
              All the list options mentioned above take file-glob-syntax wild-
              cards or package names as arguments, for example yum list avail-
              able 'foo*' will list all available packages that match  'foo*'.
              (The  single  quotes  will  keep  your  shell from expanding the
              globs.)

CLEAN OPTIONS
       The following are the ways which you can invoke yum in clean mode. Note
       that  "all  files"  in the commands below means "all files in currently
       enabled repositories".  If you want to  also  clean  any  (temporarily)
       disabled repositories you need to use --enablerepo='*' option.

       yum clean packages
              Eliminate  any cached packages from the system.  Note that pack-
              ages are not automatically deleted after they are downloaded.

       yum clean headers
              Eliminate all of the header files which yum uses for  dependency
              resolution.

       yum clean metadata
              Eliminate  all  of  the  files  which  yum uses to determine the
              remote availability of packages. Using this  option  will  force
              yum to download all the metadata the next time it is run.

       yum clean dbcache
              Eliminate  the  sqlite cache used for faster access to metadata.
              Using this option will force yum to recreate the cache the  next
              time it is run.

       yum clean all
              Runs  yum  clean packages and yum clean headers, yum clean meta-
              data and yum clean dbcache as above.

MISC
       Specifying package names
              A package can be referred to for install,update,list,remove  etc
              with any of the following:

              name
              name.arch
              name-ver
              name-ver-rel
              name-ver-rel.arch
              name-epoch:ver-rel.arch
              epoch:name-ver-rel.arch

              For example: yum remove kernel-2.4.1-10.i686

PLUGINS
       Yum  can  be  extended through the use of plugins. A plugin is a Python
       ".py" file which is installed in one of the  directories  specified  by
       the  pluginpath option in yum.conf. For a plugin to work, the following
       conditions must be met:

       1. The plugin module file must be installed in the plugin path as  just
       described.

       2. The global plugins option in /etc/yum/yum.conf must be set to '1'.

       3.  A  configuration file for the plugin must exist in /etc/yum/plugin-
       conf.d/<plugin_name>.conf and the enabled setting in this file must set
       to '1'. The minimal content for such a configuration file is:

              [main]
              enabled = 1

       See  the  yum.conf(5)  man  page for more information on plugin related
       configuration options.
