Check These Out

Detect encoding of a text file
This command gives you the charset of a text file, which would be handy if you have no idea of the encoding.

Search for a string inside all files in the current directory
Searches all files,dirs (also hidden) recursively

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

check open ports without netstat or lsof

Open a manpage in the default (graphical) web browser
An easy alias for opening a manpage, nicely HTML formatted, in your set internet browser. If you get a "command exited with status 3" error you need to install groff.

list files in mtime order
Simple but useful; list files in the current directory in mtime order. Useful if you've been working on something and then take a day or two off.

Calculate days on which Friday the 13th occurs (inspired from the work of the user justsomeguy)
Friday is the 5th day of the week, monday is the 1st. Output may be affected by locale.

List your interfaces and MAC addresses
Requires sysfs mounted on /sys - may only be useful for Linux systems. Could also use "printf '%-8s %s\n' $(basename $f) $(cat $f/address)" instead of echo.

List your largest installed packages.
Calculates the size on disk for each package installed on the filesystem (or removed but not purged). This is missing the $ | sort -rn which would put the biggest packges on top. That was purposely left out as the command is slightly on the slow side Also you may need to run this as root as some files can only be checked by du if you can read them ;)
