4. Shell Scripts

下面的 scripts 是基本 CVS 命令的集合,而且是 Korn shell 的 scripts 。你可以把他转成 perl 或者 bash。你可以自己修改成你想要的样子。 这些只是运用基本 CVS 命令但有些特殊的花样加在里面。例如, sedit 这个 script 提供了档案锁住的功能使得其他人知道有某人正在修改这个档案, 当然你也可以直接使用 CVS 命令而不用这些 scripts ,这些 scripts 只是在展示 CVS 是多麽的有弹性。

把这些 scripts 复制到 /usr/local/bin 下,并且此目录应该在你的 PATH 环境变数中。

  1. sget [-r revision_number] <file/directory name> 要从 CVS 获得一个唯读档案或整个唯读目录, 请按 sget
  2. sedit [-r revision_number] <filename> 要修改一个一个程式码时,这个 scripts 会做档案锁住的动作,因此没有别人可以登出这个档案了。当然你可以改变这个 script 成你想要的功能 - 例如不锁住,只出现警告讯息,或者相反的,非常严谨的锁档案。 请按 sedit
  3. scommit [-r revision_number] <filename> 要交出某个你修改的档案或整个目录。 把你的改变交给 CVS。 请按 scommit
  4. supdate <filename/directory> 要藉由从 CVS 得到最新的档案来update 一个档案或整个目录。 请按 supdate
  5. sunlock [-r revision_number] <filename> 要把因为用 sedit 後的档案锁关掉。这会释放档案锁(Release File Lock)。 请按 sunlock
  6. slist 要看目前正被你修改的档案列表。 做 'ls -l | grep | ...' 命令, 请按 slist
  7. sinfo <filename/directory> 要得到一个档案的改版资讯。 请按 sinfo
  8. slog <filename> 要得到一个 CVS 档案改版的历史纪录, 请按 slog
  9. sdif <filename>

    sdif -r rev1 -r rev2 <filename> 要得到你的档案与 CVS 柜子里的档案不同的地方在哪里。 请按 sdif

    注意: sdif 只有一个 'f' ,因为这里已经有一个 unix 命令叫 'sdiff'。

  10. sadd <filename> 要新增一个档案到 CVS 柜子里。 请按 sadd
  11. sdelete <filename> 要从 CVS 柜子里清掉一个档案。 请按 sdelete
  12. sfreeze <revision name> <directory name> 要冻结原始码 (freeze codes) ,这是将要发行 (release) 整个原始码目录树。 请按 sfreeze
  13. saddtree <revision name> <directory name> 要新增一个目录树到 CVS 。 请按 saddtree

    例如 :


            cd $HOME;   
            sfreeze REVISION_1_0  srctree  
    

    这将会冻结原始码,并贴上一个标签 REVISION_1_0 ,如此一来你就可以稍後用版本名字登出整个目录树。
