I have a folder /var/backup where a cronjob saves a backup of a database/filesystem. It contains a latest.gz.zip and lots of older dumps which are names timestamp.gz.zip. The folder ist getting bigger and bigger and I would like to create a bash script that does the following:
Unfortunately, I'm not a good bash scripter so I have no idea where to start. Thanks for your help.
You should learn to use the find command, possibly with xargs, that is something similar to
find /var/backup -type f -name 'foo' -mtime -20 -delete
or if your find doesn't have -delete:
find /var/backup -type f -name 'foo' -mtime -20 -print0 | xargs -0 rm -f
Of course you'll need to improve a lot, this is just to give ideas.
In zsh you can do most of it with expansion flags:
files=(*(.Om))
rm $files[1,-9]
Be careful with this command, you can check what matches were made with:
print -rl -- $files[1,-9]
