It's not completely clear to me, but what is the difference between mv and rename (from util-linux-ng 2.17.2 as /usr/bin/rename)? Are there advantages of one over the other beyond rename accepting regular expressions and mv doesn't? I believe rename can also handle multiple file renames at once, whereas mv does not do this.



I couldn't find a clear indication in their man pages what else sets them apart or through some investigation on my own.

It's basically what it says on the lid, for both.



mv is a standard utility to move one or more files to a given target. It can be used to rename a file, if there's only one file to move. If there are several, mv only works if the target is directory, and moves the files there.



So mv foo bar will either move the file foo to the directory bar (if it exists), or rename foo to bar (if bar doesn't exist or isn't a directory). mv foo1 foo2 bar will just move both files to directory bar, or complain if bar isn't a directory.



mv will call the rename() C library function to move the files, and if that doesn't work (they're being moved to another filesystem), it will copy the files and remove the originals.




On the other hand, the various rename utilities rename files, individually.



The rename from util-linux which you mention makes a simple string substitution, e.g. rename foo bar * would change foobar to barbar, and asdffoo to asdfbar. It does not, however, take a regular expression!



The Perl rename utility (or various instances of it) takes a Perl expression to transform the filenames. One will most likely use an s/pattern/replacement/ command, where the pattern is a regular expression.



Both the util-linux rename and the Perl rename can be used to move files to another directory at the same time, by making appropriate changes to the file name, but it's a bit awkward. Neither does more than call rename() on the files, so moving from one filesystem to another does not work.

mv



It's a basic command line designed to do one thing and do it well (Unix philosophy) : move file(s) or directorie(s).



You can hack STDOUT & STDIN¹ to modify on the fly the destination string, but it's just not a smart hack



rename (Perl's one)



warningThere are other tools with the same name which may or may not be able to do this, so be careful.



When people talk about rename, we think about this one, not the ELF one, less powerful (magic?).



It's not basic, it's Perl. You can pass some Perl's functions inside, and it's extremely powerful.



Consider this example :



You want to rename a bunch of files like



foobar_1.txt
foobar_2.txt
foobar_3.txt


You can prepend zeros to the digits with sprintf() like this (using regex, heh, it's Perl :D ) :



rename 's/(d+)/sprintf("%04d", $1)/e' foobar_*.txt


Now you have :



foobar_0001.txt
foobar_0002.txt
foobar_0003.txt


Not really a basic command, isn't it ?



rename is not really designed to move file(s) and dir(s), but it can do it :



$ mkdir -p /tmp/foo/bar/base
$ touch /tmp/foo/bar/base/file
$ rename 's!/tmp/foo/bar/base/file!/tmp/file!' /tmp/foo/bar/base/file


The moved file



/tmp/file



¹ some code we see on .stackexchange. websites



enter image description here



for FILE in `ls *.txt`
do
mv $FILE `echo $FILE | sed 's/anything_ugly/anything_still_ugly/'`
done


It's not the way to go, it's plain buggy, just to explain why to use the right tool at the right moment

mv simply changes the name of the file (it can also move it to another filesystem or path). You give it an old name and a new name, and it changes the file to the new name or location. rename is used to make bulk naming changes. Say you had a thousand files, foo000.log through foo999.log and you wanted to change them to bar000.log through bar999.log. With mv you'd have to do mv foo000.log bar000.log, mv foo001 bar001.log, etc. or else write a script. With rename you simply do rename foo bar foo*.log, and voila, a thousand files are changed in an instant! Pretty cool. Check out the man rename page again for details.

    mv moves or renames files and directories and will back them up; rename just renames files.



    mv has more capabilities and options. Look at the switches in the man pages for each to see the differences in capabilities. Let's take a look using man in Ubuntu 18.04LTS (your mileage may vary depending on the version of each package):



    mv options (omitting help and version)



     --backup[=CONTROL] 
    make a backup of each existing destination file

    -b like --backup but does not accept an argument

    -f, --force
    do not prompt before overwriting

    -i, --interactive
    prompt before overwrite

    -n, --no-clobber
    do not overwrite an existing file

    If you specify more than one of -i, -f, -n, only the final one takes effect.

    --strip-trailing-slashes
    remove any trailing slashes from each SOURCE argument

    -S, --suffix=SUFFIX
    override the usual backup suffix

    -t, --target-directory=DIRECTORY
    move all SOURCE arguments into DIRECTORY

    -T, --no-target-directory
    treat DEST as a normal file

    -u, --update
    move only when the SOURCE file is newer than the destination file or when the destination file is missing

    -v, --verbose
    explain what is being done

    -Z, --context
    set SELinux security context of destination file to default type


    rename options (omitting help and version)



     -s, --symlink 
    Do not rename a symlink but its target.

    -v, --verbose
    Show which files where renamed, if any.

    -n, --no-act
    Do not make any changes.

    -o, --no-overwrite
    Do not overwrite existing files.

    You can hack STDOUT & STDIN¹ to modify on the fly the destination string, but it's just not a smart hack



    rename (Perl's one)



    warningThere are other tools with the same name which may or may not be able to do this, so be careful.



    When people talk about rename, we think about this one, not the ELF one, less powerful (magic?).



    It's not basic, it's Perl. You can pass some Perl's functions inside, and it's extremely powerful.



    Consider this example :



    You want to rename a bunch of files like



    foobar_1.txt
    foobar_2.txt
    foobar_3.txt


    You can prepend zeros to the digits with sprintf() like this (using regex, heh, it's Perl :D ) :



    rename 's/(d+)/sprintf("%04d", $1)/e' foobar_*.txt


    Now you have :



    foobar_0001.txt
    foobar_0002.txt
    foobar_0003.txt


    Not really a basic command, isn't it ?



    rename is not really designed to move file(s) and dir(s), but it can do it :



    $ mkdir -p /tmp/foo/bar/base
    $ touch /tmp/foo/bar/base/file
    $ rename 's!/tmp/foo/bar/base/file!/tmp/file!' /tmp/foo/bar/base/file


    The moved file



    /tmp/file



    ¹ some code we see on .stackexchange. websites



    enter image description here



    for FILE in `ls *.txt`
    do
    mv $FILE `echo $FILE | sed 's/anything_ugly/anything_still_ugly/'`
    done


    It's not the way to go, it's plain buggy, just to explain why to use the right tool at the right moment

    mv simply changes the name of the file (it can also move it to another filesystem or path). You give it an old name and a new name, and it changes the file to the new name or location. rename is used to make bulk naming changes. Say you had a thousand files, foo000.log through foo999.log and you wanted to change them to bar000.log through bar999.log. With mv you'd have to do mv foo000.log bar000.log, mv foo001 bar001.log, etc. or else write a script. With rename you simply do rename foo bar foo*.log, and voila, a thousand files are changed in an instant! Pretty cool. Check out the man rename page again for details.

            mv moves or renames files and directories and will back them up; rename just renames files.



            mv has more capabilities and options. Look at the switches in the man pages for each to see the differences in capabilities. Let's take a look using man in Ubuntu 18.04LTS (your mileage may vary depending on the version of each package):



            mv options (omitting help and version)



             --backup[=CONTROL] 
            make a backup of each existing destination file

            -b like --backup but does not accept an argument

            -f, --force
            do not prompt before overwriting

            -i, --interactive
            prompt before overwrite

            -n, --no-clobber
            do not overwrite an existing file

            If you specify more than one of -i, -f, -n, only the final one takes effect.

            --strip-trailing-slashes
            remove any trailing slashes from each SOURCE argument

            -S, --suffix=SUFFIX
            override the usual backup suffix

            -t, --target-directory=DIRECTORY
            move all SOURCE arguments into DIRECTORY

            -T, --no-target-directory
            treat DEST as a normal file

            -u, --update
            move only when the SOURCE file is newer than the destination file or when the destination file is missing

            -v, --verbose
            explain what is being done

            -Z, --context
            set SELinux security context of destination file to default type


            rename options (omitting help and version)



             -s, --symlink 
            Do not rename a symlink but its target.

            -v, --verbose
            Show which files where renamed, if any.

            -n, --no-act
            Do not make any changes.

            -o, --no-overwrite
            Do not overwrite existing files.
