vi: 进入command状态， vi左下角出现“:”
<:>oldstringnewstring
其中的 <> 是为了方便阅读用的， 实际操作时去掉。

你可以 man 一下 sed,这个命令很有用
一般情况下，可以用：
cat source_filename | sed -e s/"sourceString"/"targetString"/g >
target_filename
如果多个文件，可以用 for 循环。

the simplest way to do this is:
find . -name "*.c" -exec vi -c "1,$ s/old_string/new_string/g" -c "wq" {} \;
will replace all old string with new string in all .c files

A more effective way would be a one line comand:
