8、col，想保存帮助页面为纯文本？
| # PAGER=cat # man less | col -b > less.txt |
9、xmlwf，需要知道一个XML文档或许是配置文件是否合理？
| # curl -s 'http://bashcurescancer.com' > bcc.html # xmlwf bcc.html # perl -i -pe 's@<br/>@<br/>@g' bcc.html # xmlwf bcc.html bcc.html:104:2: mismatched tag |
10、lsof 列出打开文件，你可以用它做很多很cool的事情，比如查找哪个接口是开放的？
| # lsof | grep TCP portmap 2587 rpc 4u IPv4 5544 TCP *:sunrpc (LISTEN) rpc.statd 2606 root 6u IPv4 5585 TCP *:668 (LISTEN) sshd 2788 root 3u IPv6 5991 TCP *:ssh (LISTEN) sendmail 2843 root 4u IPv4 6160 TCP badhd:smtp (LISTEN) vsftpd 9337 root 3u IPv4 34949 TCP *:ftp (LISTEN) cupsd 16459 root 0u IPv4 41061 TCP badhd:ipp (LISTEN) sshd 16892 root 3u IPv6 61003 TCP badhd.mshome.net:ssh->kontiki.mshome.net:4661 (ESTABLISHED) Note: OpenBSD 101 pointed out that “lsof -i TCP” a better way to obtain this same information. Thanks!Or find the number of open files a user has. Very important for running big applications like Oracle, DB2, or WebSphere: # lsof | grep ' root ' | awk '{print $NF}' | sort | uniq | wc -l 179 |
提示，匿名评论者指出应该用“sort -u”代替sort | uniq，本人忘记了-u flag，谢谢！
