Problem is, there are 3 files that I remove many times a day and would like this command to ignore these 3 files. In other words, prompt me on everything EXCEPT these 3 files.
Yes, it's possible. It's not exactly trivial to get right, because you could be passing in both files from the excluded set and other files at the same time. But let's just figure you usually delete only one file at a time.
This declares a function (instead of an alias) which assumes your regular rm is in /bin/rm -- if it's in /usr/bin/rm or elsewhere, you need to adapt the command. The variable ask is set to "-i" and then conditionally, if there is exactly one argument, and if that one argument is one of your three files (change the list to hold your exceptions) then set ask to the empty string. Then, unconditionally run the regular rm, with whatever value $ask has now, on the arguments.

Can I modify the color scheme? So that it only affects me, not everyone else?
The ls manual page mentions a variable LS_COLORS which you can set or modify in your own .bashrc. It won't affect anybody else; everybody have their own .bashrc. GNU file utilities has detailed documentation (for some version of GNU ls). It seems the regular documentation is what dircolors -p prints, and the manual doesn't explain it in too much detail.

Hi,
for example in this script I want both of these files to be listed with my "ls" command but it won't work, is there a way to do it like this I've tried &, ||, |, etc.
This seems so simple but I can't figure it out.
I thought with "&&" it would work but I was wrong!

When I telnet (ssh) over to my Fedora system, I find the colors horrible. For instance, regular files are white text, which is fine, but directories show up as dark blue which is virtually invisible against the black background). Additionally, when using vi, I find the colors great doing perl... (3 Replies)

shell-quote
SHELL-QUOTE(1) User Contributed Perl Documentation SHELL-QUOTE(1)NAME
shell-quote - quote arguments for safe use, unmodified in a shell command
SYNOPSIS
shell-quote [switch]... arg...
DESCRIPTION
shell-quote lets you pass arbitrary strings through the shell so that they won't be changed by the shell. This lets you process commands
or files with embedded white space or shell globbing characters safely. Here are a few examples.
EXAMPLES
ssh preserving args
When running a remote command with ssh, ssh doesn't preserve the separate arguments it receives. It just joins them with spaces and
passes them to "$SHELL -c". This doesn't work as intended:
ssh host touch 'hi there' # fails
It creates 2 files, hi and there. Instead, do this:
cmd=`shell-quote touch 'hi there'`
ssh host "$cmd"
This gives you just 1 file, hi there.
process find output
It's not ordinarily possible to process an arbitrary list of files output by find with a shell script. Anything you put in $IFS to
split up the output could legitimately be in a file's name. Here's how you can do it using shell-quote:
eval set -- `find -type f -print0 | xargs -0 shell-quote --`
debug shell scripts
shell-quote is better than echo for debugging shell scripts.
debug() {
[ -z "$debug" ] || shell-quote "debug:" "$@"
}
With echo you can't tell the difference between "debug 'foo bar'" and "debug foo bar", but with shell-quote you can.
save a command for later
shell-quote can be used to build up a shell command to run later. Say you want the user to be able to give you switches for a command
you're going to run. If you don't want the switches to be re-evaluated by the shell (which is usually a good idea, else there are
things the user can't pass through), you can do something like this:
user_switches=
while [ $# != 0 ]
do
case x$1 in
x--pass-through)
[ $# -gt 1 ] || die "need an argument for $1"
user_switches="$user_switches "`shell-quote -- "$2"`
shift;;
# process other switches
esac
shift
done
# later
eval "shell-quote some-command $user_switches my args"
OPTIONS --debug
Turn debugging on.
--help
Show the usage message and die.
--version
Show the version number and exit.
