I want to see what files will be deleted when performing an rm in linux. Most commands seem to have a dry run option to show just such information, but I can't seem to find such an option for rm. Is this even possible?

  • I would also like to see which files will generate errors for lack of permissions. – Simon Woodside Feb 10 '17 at 22:19

Say you want to run:

rm *.txt

You can just run:

echo rm *.txt

or even just:

echo *.txt

to see what files rm would delete, because it's the shell expanding the *.txt, not rm.

The only time this won't help you is for rm -r.

If you want to remove files and directories recursively, then you could use find instead of rm -r, e.g.

find . -name "*.txt" -print

then if it does what you want, change the -print to -delete:

find . -name "*.txt" -delete
  • find is a good choice IMO. And if you want a graphical presentation use tree. – noisebleed Jul 25 '12 at 9:49

    Almost perfect. find . -name "*.txt" -delete doesn't seem to be recursive tho. Removed all the files, but didn't remove directories that were listed in -print – Oscar Godson Jul 21 '13 at 9:17

    @OscarGodson Assuming the directories were left empty after removing the files, you can remove them with find . -type d -empty -delete – datguy Jan 3 '17 at 20:08

    @OscarGodson - find will not delete directories that still contain files (equivalent to rm dir/ without -r). You would have to empty the directory first - or use find to -exec rm with the appropriate options to do this. e.g. find . -depth -name "*.txt" -exec rm -r {} + – shalomb Apr 17 '17 at 19:08
  • Using the echo rm *.txt method seems to have a drawback. It presents the results in a concatenated list (a long string with one file after the previous one), as opposed to a vertical list. Is there any way to get the output to display in a vertical list (one file per line) ? (UPDATE: I see that the find method does what I have requested. So I'll run with that.) – inspirednz Oct 10 '17 at 4:27

You can say:

rm -i

to run it in interactive mode, so rm will prompt you to confirm whether each file should be deleted. You could just answer no to each file to see which ones would be affected.

    This is rather difficult with a large number of files. – Cory Klein Feb 7 '11 at 20:13

    yes n | rm -i #comment to meet minimum comment length – Joshua May 4 '16 at 18:46

You can use ls to list all the files that will be removed by rm:

ls ../path/*.txt

If you need to list to view the files that will be deleted with a recursive rm, then use the -R flag with ls:

ls -R ../path/*.txt
  • Good point. Though if you know the level of nesting then you can achieve this by ls */*/*.txt – Veneet Reddy Jul 24 at 9:43

    You're right. With the -R option. – Veneet Reddy Jul 24 at 10:32
