[Solved] Removing temp files in backup bash script

Hello all!! This is my first post in the Arch forums!

I am posting this in the General Programming section cause its related to my personal bash backup script.

Because I'm a little anal (and a little OCD) I'd like to remove all those pesky temp files that end in a "~" before I backup my home folder to my external drive.

I am considering adding the following code to the beginning of the script so the temp files will be deleted before the rest of the rsync backup script gets executed:

find ~ | grep '~'  | while read LINE
  do
    rm $LINE
  done

Just wondering if anyone knows of any files that I may be inadvertently deleteing that I should be keeping?

Re: [Solved] Removing temp files in backup bash script

that might work unless you had some "fi~les" on your system. grep '~$' would help that.

but,

find "$HOME" -name '*~' -delete

might be better; you could also setup your editor to not make the files to begin with.

I ran a wc -l on my code vs using the regexp "$" from your post. Looks like there's 1 file that contains a ~ somewhere other than at the end. Thank you for that tip.

I also looked at the find man page (which I shoulda done before I posted) and see that using your code I can consolidate the find and delete into one command rather than piping to read and running that until while exits.

Thanks

Re: [Solved] Removing temp files in backup bash script

If you are using bash 4:

for f in *~ **/*~; do
    [[ -f $f ]] || continue
   rm "$foo"
done
