How can I run original command that aliased with same name?

  • 772

An alias for ls command in ~/.bashrc file aliased with this one:

alias ls='ls --color=auto'

then, when I run ls command in terminal aliased ls(ls --color=auto) runs. but my question is how can I run original ls only and only ls alone without extra argument and without solving problem with deleting aliased entry? since when I delete this entry I can run it in simple ls.

command-line

  1. Best Answer

    You can bypass aliases by the following methods:

    1. the full pathname of the command: /bin/ls

    2. command substitution: $(which ls)

    3. the command builtin: command ls

    4. double quotation marks: "ls"

    5. single quotation marks: 'ls'

    6. a backslash character: \ls

  2. Suspend alias expansion

    You could also disable alias expansion for all aliases temporarily, without deleting them:

    $ shopt -u expand_aliases
$ command -v ls
/bin/ls

    To enable them:

    shopt -s expand_aliases
$ command -v ls
alias ls='ls --color=auto'

    Note that alias expansion is disabled by default in scripts, but set by default in interactive shells.

  3. You can disable an alias using \ in front of command.

    So to run the original ls command you need to run it using \ls

    For example

    • First creating alias of ls command.

      [guru@guru-Aspire-5738 /]$ alias ls='ls -l'
[guru@guru-Aspire-5738 /]$ ls
total 96
drwxr-xr-x   2 root root  4096 Sep  3 18:31 bin
drwxr-xr-x   5 root root  4096 Sep 17 02:51 boot
drwxr-xr-x   2 root root  4096 Sep  3 22:17 cdrom
drwxr-xr-x  17 root root  4520 Sep 17 21:11 dev
drwxr-xr-x 153 root root 12288 Sep 17 21:11 etc
drwxr-xr-x   3 root root  4096 Sep  3 22:17 home
lrwxrwxrwx   1 root root    37 Sep  8 21:31 initrd.img -> /boot/initrd.img-3.2.0-68-generic-pae
lrwxrwxrwx   1 root root    36 Sep  3 22:18 initrd.img.old -> boot/initrd.img-3.2.0-

      (and many more...)

    • Output of original ls using \ which override the alias.

      [guru@guru-Aspire-5738 /]$ \ls
bin    etc         lib     opt   sbin     tmp      vmlinuz.old
boot   home        lost+found  proc  selinux  usr
cdrom  initrd.img      media       root  srv      var
dev    initrd.img.old  mnt     run   sys      vmlinuz
[guru@guru-Aspire-5738 /]$

  4. You could add command before the aliased command, e.g.

    command ls

    Or run the original executable by combining which

    which ls

    It will return /bin/ls, therefore with

    `which ls`

    or

    $(which ls)

    you could execute that file directly.

  5. You can also run the command from its original location /bin/ls instead of ls
