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

Runs a command without hangups.

The improvement is that you can re-attach to the screen at a later point.

Bypass 1000 Entry limit of Active Directory with ldapsearch

Cut/Copy everything arround brackets or parentheses on vim (in normal mode)

Put the cursor on either curly braces ( {, } ). Then press d% The d is delete command, and % is movement command that move the cursor to another matching parentheses (or curly braces in this case). This action will delete every character that was on the way of the movement (from the first curly braces to the second).

Benchmark SQL Query

send a file or directory via ssh compressing with lzma for low trafic

check open ports without netstat or lsof

Show drive names next to their full serial number (and disk info)

As of this writing, this requires a fairly recent version of util-linux, but is much simpler than the previous alternatives. Basically, lsblk gives a nice, human readable interface to all the blkid stuff. (Of course, I wouldn't recommend this if you're going to be parsing the output.) This command takes all the fun out of the previous nifty pipelines, but I felt I ought to at least mention it as an alternative since it is the most practical.

0-1279 = desktop 1 region = face 1 1280-2559 = face 2 ==>> wmctrl 1280 = wmctrl (1281,...2559) are all the same for a 1280 monitor resolution math: argument of wmctrl -o = ( DesiredFace * HorizontalResolution - 1)
