split a multi-page PDF into separate files

List the URLs of tabs of the frontmost Chrome window in OS X
This also works with Safari if you just change the application name. Replace $ window 1 with $ windows to list the URLs of tabs in all windows instead of only the frontmost window. This also includes titles: $ osascript -e{'set o to""','tell app"google chrome"','repeat with t in tabs of window 1','set o to o&url of t&"\n"&" "&title of t&"\n"',end,end}|sed \$d .

Change user, assume environment, stay in current dir
I've used this a number of times troubleshooting user permissions. Instead of just 'su - user' you can throw another hyphen and stay in the original directory.

Synchronise a file from a remote server
You will be prompted for a password unless you have your public keys set-up.

Cut the first 'N' characters of a line
You can also cut charactes starting from X to N.

Watch active calls on an Asterisk PBX
Only the number of calls nothing else.

Find top 5 big files
zsh: list of files sorted by size, greater than 100mb, head the top 5. '**/*' is recursive, and the glob qualifiers provide '.' = regular file, 'L' size, which is followed by 'm' = 'megabyte', and finally '+100' = a value of 100

Grep by paragraph instead of by line.
This is a command that I find myself using all the time. It works like regular grep, but returns the paragraph containing the search pattern instead of just the line. It operates on files or standard input. $ grepp or $ | grepp

Remove everything except that file
Remove everything except that file with shell tricks inside a subshell to avoid changes in the environment. $ help shopt
