Filter the output of locate not to show the Duplicates in rsnapshot

  • 772

When I use locate on my server and the result is in my rsnapshot backup then I get all those duplicates.

I could use grep to filter out all rsnapshot files:

locate something_in_backup | grep -v /var/cache/rsnapshot

but then I would miss files in the backup that are coming from other servers.

How could I filter the output to show only results from the rsnapshot/daily.0/ folder?

rsnapshot grep

  1. You can use regular expressions in the grep command:

    locate something_in_backup | grep -v 'rsnapshot/\(hourly.[1-5]\|daily\|weekly\|monthly\)'

    or if you don't backup hourly:

    locate something_in_backup | grep -v 'rsnapshot/\(daily.[1-7]\|weekly\|monthly\)'

    note the right escaping of pipe and brackets
