More precise BASH debugging

Pimp your less
# s = combine multiple lines of whitespace into 1 # x4 = set the tabstop to 4 instead of 8 # F = Exit if the output fits on 1 screen. This is similar to git diff # R = Raw control chars. This allows you to pipe colordiff straight to less. ie: alias sdi="svn diff | colordiff | less" # S = Chop off long lines # X = Dont send termcap init and deinit scrings to the terminal

Change prompt to MS-DOS one (joke)

Scan all open ports without any required program

Monitor logs in Linux using Tail
Works in Ubuntu, I hope it will work on all Linux machines. For Unixes, tail should be capable of handling more than one file with '-f' option. This command line simply take log files which are text files, and not ending with a number, and it will continuously monitor those files. Putting one alias in .profile will be more useful.

count processes with status "D" uninterruptible sleep

enable all bash completions in gentoo

Tells you where a command is in your $PATH, but also wether it's a link and to what.
You may also use the $(which foo) variant instead of backticks. I personnaly have an alias ll='ls -l'.
