getcwd() is a rather expensive operation...are you sure you want to do
this?

Considering the alternatives (and without actually doing any time
studies), yes I think it ITRTD. The alternatives (as I see
them) are as follows:
1) use getcwd(3)
2) hack together sh(1)'s own version of getcwd()
3) use the fork/exec/pipe cruft of /bin/pwd that was there
I prefer option #1, since I don't have to reinvent the wheel as
I would have to in option #2. Option #3 is IMHO wrong since /bin/pwd
essentially calls getcwd(3) and option #1 does this without the
overhead of fork/exec and reading the results from a pipe. Perhaps
if our version of getcwd(3) is sooooo slow, we should look into
improving it so that all programs that use it can benefit from it. :)

Sorry, I had thought that you were calling getcwd() twice. Now that I have
the changes here, I see that my assumption was wrong. So nevermind...

steve 96/12/24 15:59:54
Modified: bin/sh trap.c
Log:
With these changes sh(1)'s trap command should be POSIX-compliant,
while remaining (becoming :) compatible with other popular shells.
Specifically these changes include:
1) Implement 'trap -l' to get a list of valid signals names. This
is useful if you wanted to do something like reset all signal
handlers to there defaults values, in which case something like
this will do the trick.
trap `trap -l`
2) Reformat the output of 'trap' so it can be saved and later eval'd
to restore the saved settings.
3) Allow the use of signal names as well as signal numbers.
4) Fix trap handling of SIGCHLD so that commands like the following
(albeit, contrived) won't cause sh(1) to recurse ad infinitum.
trap uname 0 20
5) Make variables static that are used only in trap.c.
6) Minor 'style(9) police' mods.
