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

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.
alias ls="ls --classify"in there.
