[Tools] P4 应用
来点PERFORCE 应用实例。
function ： 把当前workspace中的所有文件（local file & P4 file）打成label

perl -pi -e "s/you/me/g" file
-e 参数允许执行 Perl 代码
-p 参数确保处理文本的每一行并且将处理后的结果打印出来
-i 参数将修改的结果应用到文件中（所以看不到 -p 打印的内容了）
-n 表示遍历所有行（类似 -p 但不负责打印结果）
p4 revert
|
|
Revert only those files that haven't changed (in terms of content or filetype) since they were opened. |
|
|
Keep workspace files; the file(s) are removed from any changelists and Perforce records that the files as being no longer open, but the file(s) are unchanged in the client workspace. |
