Check These Out

shuffle lines via perl
Same, without modules... Probably smarter option: just use the shuf command or even sort -R.

Get info about remote host ports and OS detection
Where < target > may be a single IP, a hostname or a subnet -sS TCP SYN scanning (also known as half-open, or stealth scanning) -P0 option allows you to switch off ICMP pings. -sV option enables version detection -O flag attempt to identify the remote operating system Other option: -A option enables both OS fingerprinting and version detection -v use -v twice for more verbosity. $ nmap -sS -P0 -A -v < target >

Monitor memory usage
Monitor with watch command and vmstat, memory usage

Speed up launch of firefox
Compress information DBs of firefox to speed up the launch of browser.

Find files modified since a specific date
This command uses -newerXY to show you the files that are modified since a specific date. I recommend looking for "-newerXY" on the manpage to get the specifics.

Stripping ^M at end of each line for files
just deletes to rogue CR from dos files, and tr is always available.

Remove invalid host keys from ~/.ssh/known_hosts
Useful if you have to tunnel ssh through a local port and it complains of the host key being different. Much easier than manually editing the file.

Git diff last two commits
How about this one ?

Test http request every second, fancy display.
Use the command watch, which is really hard to pass nested quotes to, and insert newlines where they are supposed to go in the HTTP request. that is after 1.1 after the host and two newlines at the end before the EOF. i use this all day what? no support for HEREDOCs on commandlinefu's interface? need more fu.

kill all process that belongs to you
