Shell and Shell Script for Linux

Posted on 2011-12-17 14:50 CT 阅读(115) 评论(0)  编辑 收藏 引用
Shell, shell script and other scripts are very important to learn and master linux.

  1. Fetch lines containing 'MAN' from /etc/man.config, and exclude comment lines.
    $ cat /etc/man.config | grep 'MAN' | grep  -v '^#'
    $ cat /etc/man.config | grep 'MAN' | sed 's/#.*$//g' | sed '/^$/d'
  2. Delete comment and blank lines using extended regular express.
    $ egrep -v '^$|^#' /etc/man.config
