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。
sget [-r revision_number] 要从 CVS 获得一个唯读档案或整个唯读目录,请按 sget sedit [-r revision_number] 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 scommit [-r revision_number] 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 supdate 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 sunlock [-r revision_number] 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 slist 要看目前正被你修改的档案列表。做 'ls -l | grep | ...' 命令,请按 slist sinfo 要得到一个档案的改版资讯。 请按 sinfo slog 要得到一个 CVS 档案改版的历史纪录,请按 slog sdif sdif -r rev1 -r rev2 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'。
sadd 要新增一个档案到 CVS 柜子里。请按 sadd sdelete 要从 CVS 柜子里清掉一个档案。请按 sdelete sfreeze 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 saddtree 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。
