Convert unix timestamp to date
The "-d" option for gnu's "date" command can calculate positive or negative offset from any time, including "now". You can even specify a source timezone (the output timezone can be set with the TZ environment variable). Useful! Fun! Not very well documented!

Find all plain text files that do not contain STRING

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

Copy the full path of a file to the clipboard (requires xclip or similar)
Handy for those times you need to paste a file path in an IDE or some other app. sudo apt-get install xclip Then, for convenience, alias xclip to 'xclip -selection c' so you can just do something like realpath . | xclip

Get your current Public IP

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Get absolut path to your bash-script
Another way of doing it that's a bit clearer. I'm a fan of readable code.

Replace 'csv_file.csv' with your filename.
