grep得到的内容用sed处理

-E or Extended Regular Expressions

I mentioned extended regular expressions earlier. FreeBSD (and Mac OS X) uses “-E” to enable this. However, FreeBSD later added the -r command to be compatible with GNU sed.

-e <script>或--expression=<script> 以选项中指定的script来处理输入的文本文件。

Multiple commands with -e command

One method of combining multiple commands is to use a -e before each command:

sed -e ‘s/a/A/’ -e ‘s/b/B/’ new

A “-e” isn’t needed in the earlier examples because sed knows that there must always be one command. If you give sed one argument, it must be a command, and sed will edit the data read from standard input.

The long argument version is

sed --expression=‘s/a/A/’ --expression=‘s/b/B/’ new

# -E 可以省略
