Rename multiple files at the same time
Solution 1
Renaming files using mmv:
$ mmv '???-*' '#4'
^^^ ^ ^
123 4 4
You could also match digits with range match:
$ mmv '[0-9][0-9][0-9]-*.txt' '#4.txt'
^ ^ ^ ^ ^
1 2 3 4 4
(recursively rename files):
$ mmv ';???-*' '#1#5'
^^^^ ^ ^ ^
1234 5 1 5
-
;
Expands to any number of directories (same as**/
). -
*
Matches any char zero or more times. -
?
Matches any single character. -
[]
Matches a list or and a range of characters. -
#
References to the nth wildcard char in the from pattern.
Solution 2
With Perl-based rename
command:
$ rename -n 's/\d{3}-//' [0-9][0-9][0-9]-*.txt
rename(000-hello.txt, hello.txt)
rename(001-world.txt, world.txt)
rename(002-ubuntu.txt, ubuntu.txt)
rename(003-linux.txt, linux.txt)
If the number of files is large enough to make the command exceed the shell's ARG_MAX
, then you could use either
printf '%s\0' [0-9][0-9][0-9]-*.txt | xargs -0 rename -n 's/\d{3}-//'
or
find . -maxdepth 1 -name '[0-9][0-9][0-9]-*.txt' -exec rename -n 's/\d{3}-//' {} +
Note that [0-9][0-9][0-9]-*.txt
is processed by the shell and needs to be a shell glob expression rather than a regular expression.
Remove the -n
once you are happy that it is doing the right thing.
Solution 3
Since I don't see it mentioned here yet, you can use repren. While it isn't installed by default, it does support regular expression-based file renaming. You can do just a single regular expression pattern like so:
repren --rename --from "^[0-9]{3}" --to "" --dry-run .
The above example deletes the first 3 digits in all filenames if they are at the beginning thereof for all files recursively in the current directory. It does a dry run though to show you what it will do without actually doing it - remove the --dry-run
bit once you're sure that it will do what you intend.
repren
also supports pattern files, allowing you to do multiple replacements in 1 go:
repren --rename --patterns=path/to/patternfile
A pattern file looks like this:
regex_1<tab_character>replacement_1
regex_2<tab_character>replacement_2
...and so on.
Finally, it supports regular expression groups. Consider this pattern file:
# This is a comment
figure ([0-9+])<tab>Figure \1
The \1
syntax inserts the contents of the first (bracketed)
group. To do this on the command-line, you'd need to use single quotes I think (correct me if I'm wrong):
repren --rename --from 'figure ([0-9+])' --to 'Figure \1' --dry-run path/to/directory_or_files_here
This is just scratching the surface of what repren
is capable of though. It can optionally alter the contents of files too (hence the need for --rename
in all the above examples).
Disclaimer: I am not affiliated with repren
or it's development in any way, I just find it an invaluable time-saving tool.
Solution 4
I've done this often in the past using the bulkrename
command in ranger
, a terminal based file browser. The steps are as follows:
- Navigate to the directory that contains the files.
- Select all files to be renamed. If you want to select everything within that directory, simply press
v
. - Use the
:bulkrename
command, this takes you to a list of all the selected file names in vim or your default editor. - Manipulate the file names in vim to your liking and save!
Solution 5
I know the question is tagged with command-line, but if a GUI tool would be useful to you, the Thunar file manager has a great bulk-rename tool. You can install Thunar directly from your package manager. Once it's installed, select the files of interest and then go to "Rename" under the Edit menu.
One big advantage of Thunar is that it gives you a preview of the new names, so you don't have to get your command or regex exactly right the first time. It can also do renaming tasks that are beyond the purview of regexes, like inserting consecutive numbers into file names.
There's more info about Thunar on the Ubuntu package website. Free Software Magazine has a nice overview article about it too, with screenshots.

I have around 180 files with the same structure:
000-aaaaaaaa.txt
.Regular expression for a file name:
/^[0-9]{3}\-[a-zA-Z]+$/gi
(3 digits +-
+ letters +.txt
).I would like to cut of the numeral part and
-
in each file nameFor example
000-hello.txt
->hello.txt
001-world.txt
->world.txt
002-ubuntu.txt
->ubuntu.txt
003-linux.txt
->linux.txt

bac0n over 4 yearswill this be subject to 'too many arguments' ?
-
xenoid over 4 yearsNot with 180 matching files. If you have thousands of files, you can do
ls | xargs rename s/foo/bar/
orfind ... -exec rename s/foo/bar/ +
-
steeldriver over 4 years@xenoid I've added some options for that
-
xenoid over 4 years@steeldriver That
printf
thing has been added to my bag of tricks :) -
bac0n over 4 yearsthink you can skip xargs, and go printf ... rename --null only
-
steeldriver over 4 yearsThis deserves more love - people seem to be resistant to
mmv
/mcp
(perhaps because of the unfamiliar syntax?). Maybe that will change aszsh
(which has an equivalentzmv
) becomes more popular. -
Sadaharu Wakisaka over 4 yearsWelcome to AskUbuntu, this is not an exact answer of the question and
rename -n
does show preview. -
0xC0000022L about 4 yearsWait, so you're a suspicious person but you're trusting yourself unconditionally to get the shell script right? And you parse the output of
ls
? Something doesn't check out here. Bad advice. -1 from me. Sorry. -
0xC0000022L about 4 yearsIt's a cool tool. But is there a version that will work on Python 3.x? At the moment this looks like Python 2.x only. Which is bad given Python 2.x just dropped out of support from its authors.
-
Asifa.K about 4 years@0xC0000022L Oh my! I hadn't noticed it was Python because I have it installed from source as a git submodule in my ~/bin directory. Have you tried
python3 path/to/repren
? -
0xC0000022L about 4 yearsat first glance it works. But I could not find anything that suggested there is support for Python 3.x. The fact that the main function runs doesn't mean it's been tested deep into all kinds of call paths. And it requires quite a leap of faith to commit to a new tool (however nice it appears to be) when the runtime environment for which it was written is deprecated. Besides, especially for this sort of operations I don't want trial&error as my mode of operation. The
setup.py
also only mentioned Python 2.7 explicitly. -
Asifa.K about 4 years@0xC0000022L Hrm. Perhaps someone's forked it? I did write this answer 3 years ago, so I'm unsure of the current situation. I would be interested to know if you find a solution.
