An standalone executable works, but I can't see why would you
want to set your CWD to /usr/bin. It happens many times to me to
create /usr/local/myapp, and do ln -s /usr/local/myapp/bin/*
/usr/local/bin/, which is when my script works (to find
/usr/local/myapp perhaps).

What do you do when redhat does that? BTW, it seems to me like
a bug in which(1), either in code, or documentation:
####
[EMAIL PROTECTED] behdad]$ man which | tail -54 | head -2
--tty-only
Stop processing options on the right if not on tty.
[EMAIL PROTECTED] behdad]$ alias | grep which
alias which='alias | /usr/bin/which --tty-only --read-alias
--show-dot --show-tilde'
[EMAIL PROTECTED] behdad]$ which giveaway
~/bin/giveaway
[EMAIL PROTECTED] behdad]$ echo "`which giveaway`"
/home/behdad/bin/giveaway
[EMAIL PROTECTED] behdad]$ which ls
alias ls='ls --color=tty'
/bin/ls
[EMAIL PROTECTED] behdad]$ echo "`which ls`"
alias ls='ls --color=tty'
/bin/ls
[EMAIL PROTECTED] behdad]$ echo "`\which ls`"
/bin/ls
[EMAIL PROTECTED] behdad]$
###
But isn't it supposed to ignore --read-alias like it ignoring
--show-tilde??

The clean way of setting home dirs etc is perhaps through
configure (no runtime then :( ).

PS. Perhaps it's too soon, but: "Everybody, come to Ottawa Linux
