e.g dig SRV _someservice._port.hostname.domainame.com.my OR dig SRV _https._ICMP.host.takizo.com

e.g. rm -rf backup-20070[8-9]-*

would delete :

• backup-200708-morning
• backup-200708-evening
• backup-200709-night
• backup-200709-latenight

but not :

• backup-200706-morning
• backup-200707-afternoon
• backup-200711-midnight

e.g. ls backup-20070[1-9] would list all backup starting from January to September but leave October, November & December out, of year 2007.

sed -e 1d -e 50d -e ‘/junks/d’

would remove first and 50th line & any line(s) with the word “junks”.

sed -e ‘/^$/d’

would remove every empty line
