Check These Out

Create a mirror of a local folder, on a remote server
Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)

Find usb device
I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

Recursive find and replace file extension / suffix (mass rename files)
Find recursively all files in ~/Notes with the extension '.md' and pipe that via xargs to rename command, which will replace every '.md' to '.txt' in this example (existing files will not be overwritten).

On screen display of a command.
This is very useful if you need to show someone some text from a distance. (Like someone standing over your shoulder...) I'd recommend aliasing it to something like: alias osd_cat="osd_cat -o 400 -s 8 -c blue -d 60 -f -*-bitstream\ vera\ sans-*-*-*--200-*-*-*-*-*-*-*" xosd is the utility that provides osd_cat.

hibernate

Setup an ssh tunnel
Uses ssh as tunnel tunnel for an other connection. -f runs ssh in the background -N tell that there is no command to run -L deals with the forwarding aspect where the first number is the local port number, the second is parameter is the name of the server to forward to and the third parameter is the port number on that server. The last part of the command is the usual ssh form consisting of the user name and remote server name

Make changes in any profile available immediately/Change to default group
Changes your group to the default group, has the same effect as sourcing your profile/rc file (in any shell) or logging out and back in again.

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