I thought that I could get this from $0. But in my tests, if the script is on the PATH and I invoke it just with its name, I get just its name in return. For example:
PATH=/usr/local/bin /usr/local/bin/dd.sh contains: #!/bin/sh echo $0 I invoke via: $dd.sh result is dd.sh with no indication of where it came from. Even worse: cd /usr/local/bin mv dd.sh .. ln -s ../dd.sh temp.sh temp.sh results in: ../dd.sh I don't know that it was invoked by "temp.sh", so I can't do a which to find out where it is from. I want to know so that I can have some scripts in a subdirectory which are not on the PATH. I then have a symlink to the "driver script" which is on the PATH. The "driver script" needs to determine the directory that it actually came from (the regular file, not the symlink) so that it can change the PATH for the duration of the script in order to execute other program and scripts from that same directory. I'm likely missing something simple. I hope.
