My ls command is aliased to have certain options automatically applied, including --classify (same as -F) Normally this is fine and I don't want to screw around with my .bashrc file.

Just this one time, I want to turn off --classify but don't see how even after reading the info page and some googling. There's no --classify=none or --classify=off or --no-classify or anything else I could guess.

This is on Red Hat linux in a bash shell.

Check to see if you specified an alias for ls in your .profile ? Perhaps you set alias ls="ls --classify" in there. – rlb.usa Dec 9 '10 at 22:36

You can turn off --classify selectively by using --indicator-style=none:

$ alias  lc='ls --classify --color=auto'
$ lc -ld foo bar baz
drwxr-xr-x 6 user group  4096 2010-07-19 09:09 foo/
-rwxr--r-- 1 user group 19035 2010-09-30 17:39 bar*
-rw-r--r-- 1 user group    26 2010-11-29 00:44 baz
$ lc -ld --indicator-style=none foo bar baz
drwxr-xr-x 6 user group  4096 2010-07-19 09:09 foo
-rwxr--r-- 1 user group 19035 2010-09-30 17:39 bar
-rw-r--r-- 1 user group    26 2010-11-29 00:44 baz

Where Unix is, there is always a clean solution: Thanks for providing it! – Eureka Dec 10 '10 at 17:25
Changed this to the best answer, the one true way. The backslash or single-quotes does work, but remove all the options in the alias, some of which I continue to want. This --indicator-style option, assuming I will remember it, neatly turns off just the one thing I want off. Very nice! – DarenW Dec 17 '10 at 2:10

You could re-alias it with whatever options you want, and it would be reset to whatever is in your .bashrc file on your next session.

I don't want the one-time (or three-time, since I make mistakes) modification to the options to last beyond the immediate use. – DarenW Dec 17 '10 at 2:08

After defining an alias, it remains possible to ask bash to use the unaliased command when necessary, using one of the following syntaxes:

$ 'ls'
$ \ls 

Others tips (howto remove it, etc) about the alias command are available in the dedicated "alias" Wikipedia article.

This solves my immediate problem, thanks! But it would still be nice to know how to turn off only one of several options set by the alias. – DarenW Dec 9 '10 at 22:58
If you know that the ls command is an alias, you can remove unwanted option temporarly by dynamicaly generating the "cleaned" ls command using the return of a sed: $(alias ls | cut -f2 -d'=' | sed 's/-l//') myrep to remove a -l, for example. – Eureka Dec 10 '10 at 9:24

You can temporarily disable aliases by using a \ with the command.
