Chaotic World

 회사에서 현재 CVS와 SVN으로 소스관리를 하고 있다.
처음 회사에 들어와서 환경 셋업을 할 때 WinCVS(http://www.wincvs.org)를 인스톨하여 사용을 했고, 지금까지 그래왔다.
하지만 앞으론 나도 shell에서 command를 이용하여 소스관리하는 것에 익숙해지고 싶다.
(왜?? 이런것에 익숙해지면 OS종류에 따라 똑같은 프로그램을 다시 설치하고 또 거기에 맞추는 번거로운 일은 없을 테니까...)

bash에서 'cvs --help'를 해 보았다.

$ cvs --help Usage: cvs [cvs-options] command [command-options-and-arguments]   where cvs-options are -q, -n, etc.     (specify --help-options for a list of options)   where command is add, admin, etc.     (specify --help-commands for a list of commands      or --help-synonyms for a list of command synonyms)   where command-options-and-arguments depend on the specific command     (specify -H followed by a command name for command-specific help)   Specify --help to receive this message The Concurrent Versions System (CVS) is a tool for version control. For CVS updates and additional information, see     the CVS home page at http://cvs.nongnu.org/

음.. usage에 있는 cvs-options를 보고 싶으면 --help-options를 하랜다.
command를 보고 싶으면 --help-commands를, command와 동의어를 보고 싶으면 --help-synonyms를 하라고 하네.
또 command-options-and-arguments를 보고 싶으면 -H 뒤에 커맨드 이름을 적어넣으랜다.

해보자.

'cvs --help-options'다.

$ cvs --help-options CVS global options (specified before the command name) are:     -H           Displays usage information for command.     -Q           Cause CVS to be really quiet.     -q           Cause CVS to be somewhat quiet.     -r           Make checked-out files read-only.     -w           Make checked-out files read-write (default).     -n           Do not execute anything that will change the disk.     -t           Show trace of program execution -- try with -n.     -v           CVS version and copyright.     -T tmpdir    Use 'tmpdir' for temporary files.     -e editor    Use 'editor' for editing log information.     -d CVS_root  Overrides $CVSROOT as the root of the CVS tree.     -f           Do not use the ~/.cvsrc file.     -z #         Use compression level '#' for net traffic.     -a           Authenticate all net traffic.     -s VAR=VAL   Set CVS user variable. (Specify the --help option for a list of other help options)

다른건 아직 써보질 않아서 모르겠고, 아마 제일 많이 사용되는 옵션이 '-d'가 아닐까...
환경변수로 '$CVSROOT'가 등록이 되어 있다면 그것이 사용되겠지만,
커맨드를 입력할 때 다른 CVSROOT로 접근을 하려 한다면 이 옵션을 이용하여 그 뒤에 이어서 CVSROOT를 명기해줘야 한다.

이번엔 'cvs --help-commands'다.

$ cvs --help-commands CVS commands are:         add          Add a new file/directory to the repository         admin        Administration front end for rcs         annotate     Show last revision where each line was modified         checkout     Checkout sources for editing         commit       Check files into the repository         diff         Show differences between revisions         edit         Get ready to edit a watched file         editors      See who is editing a watched file         export       Export sources from CVS, similar to checkout         history      Show repository access history         import       Import sources into CVS, using vendor branches         init         Create a CVS repository if it doesn't exist         log          Print out history information for files         login        Prompt for password for authenticating server         logout       Removes entry in .cvspass for remote repository         pserver      Password server mode         rannotate    Show last revision where each line of module was modified         rdiff        Create 'patch' format diffs between releases         release      Indicate that a Module is no longer in use         remove       Remove an entry from the repository         rlog         Print out history information for a module         rtag         Add a symbolic tag to a module         server       Server mode         status       Display status information on checked out files         tag          Add a symbolic tag to checked out version of files         unedit       Undo an edit command         update       Bring work tree in sync with repository         version      Show current CVS version(s)         watch        Set watches         watchers     See who is watching a file (Specify the --help option for a list of other help options)

이번엔 'cvs --help-synonyms'

대충 이런 식이다. 음..그러나 여전히 잘 모르겠다..ㅡㅡ;;
