Check These Out

Clean up poorly named TV shows.
Replace 'SHOWNAME' with the name of the TV show. Add -n to test the command without renaming files. Check the 'sample output'.

List users with running processes
This is different that `who` in that who only cares about logged-in users running shells, this command will show all daemon users and what not; also users logged in remotely via SSH but are running SFTP/SCP only and not a shell.

silent/shh - shorthand to make commands really quiet
Sometimes I just want to run a command quietly but all that keyboard shifting makes my fingers hurt. This little function does the job eg.: $ if shh type less; then PAGER=less; fi

Print all lines in a file that are not a certain length
Alternatively, print all the lines that are a certain length: $awk 'length($0)==12 {print}' your_file_name

Show directories in the PATH, one per line
The output of "echo $PATH" is hard to read, this is much easier. The parentheses ensure that the change to the input field separator (IFS) only happens the the sub shell and not affecting the current shell.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

List .log files open by a pid
Uses lsof to display the full path of ".log" files opened by a specified PID.

Show the command line of a process that use a specific port (ubuntu)

use wget to check if a remote file exists
put your link [url] to check if exist the remote file

search installed files of package, that doesn't remember his name well. On rpm systems
rpm, sometimes, is not wildcard friendly. To search files installed from package this could be useful. change PACKAGENAME to any package do you want to search
