"Pretty print" $PATH, show directories in $PATH, one per line with replacement pattern using shell parameter expansion

Opens vi/vim at pattern in file
Open up vi or vim at the first instance of a pattern in [file]. Useful if you know where you want to be, like "PermitRootLogin" in sshd_config. Also, vi +10 [file] will open up a file at line 10. VERY useful when you get "error at line 10" type of output.

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

dmesg with colored human-readable dates

Take a file as input (two columns data format) and sum values on the 2nd column for all lines that have the same value in 1st column
Example: $ cat

Why remember? Generate! Up to 48 chars, works on any unix-like system (NB: BSD use md5 instead of md5sum)
