I believe your program will be indispensible to all unix users. First of
all, i use tcsh instead of bash. after changing my sh to bash, I put the
function d into .bashrc and source it. the dirstack.sh is placed into
/usr/local/bin then I type "d"

ok

a
b
c
etc prints out, but they are all empty.

Finally, what should i modify if i want your prog to run under tcsh?

The code I posted is for bash; I don't use tcsh as it's not
recommended for scripting, and there's no point to learning an
entirely different shell language for interactive use.

Thanks. I find it incredibly useful. It's part of a small suite
of scripts that greatly facilitate running Linux from the
commandline. I tried all the file managers and didn't like them.

Could be that you use a different version of awk.

See comp.lang.awk for help if that turns out to
be the case.

Putting "set -x" at the top will aid in troubleshooting the
script.

Might be a copying error. "cat -A" will show the non-printing
characters.

Don't know, See comp.unix.shell.

OT: I suggest use a more conventional alias. I almost killfiled
you and dumped your posts because you looked like a stinking
troll. If you do change it, indicate that fact in your next
post.

well, cd with no argument goes to your home directory.

Since you are using tcsh, you should use the built-ins pushd and popd.

pushd remembers your current directory, and goes to a new one.

popd returns you to your old directory.

If you type pushd with no arguments, it changes place with the last directory.

Also - when you do this - it shows you the current directory stack.
You can pop back several directories by using a number.

if your directory stack is
/dir1 /dir2 /dir3
Then
pushd +2
will take you to /dir3 instead of /dir1


You might also want to use this in your .cshrc file

alias = 'set \!:1="$cwd"'

This lets you "remember" a directory by a name. That is

= Here
then when you want to go to that directory, just type

cd Here
No $ is necessary.
