commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Functions: find touch

This has helped me numerous times trying to find either log files or tmp files that get created after execution of a command. And really eye opening as to how active a given process really is. Play around with -anewer, -cnewer & -newerXY

Functions: egrep wget xargs

xargs can be used in this manner to download multiple files at a time, and xargs will in this case run 10 processes at a time and initiate a new one when the number running falls below 10.

dsh - Distributed shell, or dancer?s shell ;-)

you can put your servers into /etc/dsh/machines.list than you don't have to serperate them by commata or group them in different files and only run commands for this groups

dsh -M -c -a -- "apt-get update"

scutil --dns

Same as:

1 rpm -ivh package.rpm

2 yum localinstall package.rpm

3 Edit /etc/yum.conf or repository.repo and change the value of gpgcheck from 1 to 0 (!dangerous)

rkhunter (Rootkit Hunter) is a Unix-based tool that scans for rootkits, backdoors and possible local exploits. rkhunter is a shell script which carries out various checks on the local system to try and detect known rootkits and malware. It also performs checks to see if commands have been modified, if the system startup files have been modified, and various checks on the network interfaces, including checks for listening applications.

chkrootkit -x | less

grab the weather, with a little expletive fun. replace the 48104 with a US zipcode, or the name of your city (such as ZIP="oslo"), unless you want to know what the weather is like for me (and that's fine too)
