How to simply remove everything from a directory on Linux

  • 772

How to simply remove everything from a current or specified directory on Linux?

Several approaches:

  1. rm -fr *
    rm -fr dirname/*
    Does not work — it will leave hidden files — the one's that start with a dot, and files starting with a dash in current dir, and will not work with too many files

  2. rm -fr -- *
    rm -fr -- dirname/*
    Does not work — it will leave hidden files and will not work with too many files

  3. rm -fr -- * .*
    rm -fr -- dirname/* dirname/.*
    Don't try this — it will also remove a parent directory, because ".." also starts with a "."

  4. rm -fr * .??*
    rm -fr dirname/* dirname/.??*
    Does not work — it will leave files like ".a", ".b" etc., and will not work with too many files

  5. find -mindepth 1 -maxdepth 1 -print0 | xargs -0 rm -fr
    find dirname -mindepth 1 -maxdepth 1 -print0 | xargs -0 rm -fr
    As far as I know correct but not simple.

  6. find -delete
    find dirname -delete
    AFAIK correct for current directory, but used with specified directory will delete that directory also.

  7. find -mindepth 1 -delete
    find dirname -mindeph 1 -delete
    AFAIK correct, but is it the simplest way?

    rm -fr * .*
    Will work fine with at least GNU rm as it has special code to exclude "." and ".."

    $ id
uid=65534(nobody) gid=65534(nogroup) groups=65534(nogroup)
$ cd /tmp
$ mkdir rmtest
$ cd rmtest
$ touch .test
$ ls -la
total 8
drwxr-xr-x 2 nobody nogroup 4096 2009-08-19 15:37 .
drwxrwxrwt 7 root   root    4096 2009-08-19 15:37 ..
-rw-r--r-- 1 nobody nogroup    0 2009-08-19 15:37 .test
$ rm -rf .*
rm: cannot remove `.' or `..'
rm: cannot remove `.' or `..'
$ ls -la
total 8
drwxr-xr-x 2 nobody nogroup 4096 2009-08-19 15:37 .
drwxrwxrwt 7 root   root    4096 2009-08-19 15:37 ..

    FreeBSD rm man page says "It is an error to attempt to remove the files /, . or ..", so it probably works there too if you specify the force flag to ignore the error.

  2. To add to your list, lets say you want to delete everything in the directory foo and all sub directories (that is what your find command does). I always found the simplest was:

    #for dir foo with /home/kbrandt/foo
rm -rf /home/kbrandt/foo && mkdir /home/kbrandt/foo

    If you don't want to delete the sub directories, modify your find command to include -type f

  3.  rm -rf directory

    It'll effectively nuke everything, including the directory itself.

  4. Why not a simple 

    ls -la <selected dir>| xargs rm -Rf

    ?

    It will generate errors for "." & ".." but it will drop everything else.

  5. Here's something that just worked for me:

    zip -rm foo *
rm foo.zip

    It may not be the most efficient method, but it worked.
