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 WoodsideFeb 10, 2017 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 . -depth -name "*.txt" -print
then if it does what you want, change the -print
to -delete
:
find . -depth -name "*.txt" -delete
(-delete
implies -depth
, we're still adding it as a reminder as recommended by the GNU find
manual).

find is a good choice IMO. And if you want a graphical presentation use

2Almost 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

1@OscarGodson Assuming the directories were left empty after removing the files, you can remove them with
find . -type d -empty -delete

1@OscarGodson -
find
will not delete directories that still contain files (equivalent torm dir/
without-r
). You would have to empty the directory first - or usefind
to-exec rm
with the appropriate options to do this. e.g.find . -depth -name "*.txt" -exec rm -r {} +

1Using 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 thefind
method does what I have requested. So I'll run with that.) Oct 10, 2017 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.

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

Just wanted to belatedly point out a handy solution that Joshua mentioned in the comments:
yes n | rm -i myFile1 myFile2 myFile3
This runs rm
in interactive mode, which prompts a y/n response for each file it would delete, but via yes n
it automatically declines this prompt for each file. The output isn't super pretty, but is parseable with a little cleanup.

1Doesn't work for recursive rm because that asks for confirmation before descending into directories Jan 26, 2022 at 13:56
