The ssh command is an amazing program. You can use it for opening sessions between server or you can use it run a command on a remote system, non-interactively. A simple example of which might be getting file system usage:
This simple linux bash script will delete subdirectories in a directory based on when the subdirectory was last modified. In my sample script, it looks in the directory /home/backup and deletes any directories older than 7 days. Replace 7 with the number of days of your choosing! Just to explain: -maxdepth 1 = list only files/directories in 1 level from main search directory -type d = list only directories -mtime +7 = modified time of more than 7 days -print = print out list; so we can then process the list with our bash script This is useful for backup programs which do not clean up their old backups.
