VIM subst any char different from literal " + EOL with searched string + white space

Find non-standard files in mysql data directory
These files should be removed to keep the size of data directory under control. If you exclude the known important file types like frm and MYD then what-ever is left can be either moved or deleted.

Decrypt passwords from Google Chrome and Chromium.
Read this before you down voting and comment that it is not working -> Wont work on latest versions ~75> since database file is locked and has to be decrypted. This is useful if you have an old hdd with a chrome installation and want to decrypt your old passwords fast.

Replace 'csv_file.csv' with your filename.

Backup file, create dir and set perms in one shot
Prior to working on/modifying a file, use the 'install -m' command which can both copy files, create directories, and set their permissions at the same time. Useful when you are working in the public_html folder and need to keep the cp'd file hidden.

Remote mysql dump all databases with ssh

command shell generate random strong password
shell generate random strong password

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.
