Re: Finding out how you were called...

$0 stores the name that the program was run as..

Either I completely misread the question or you added the bit about $0 after I wrote this :)

$0 (for me, on RH 7.1) contains the full path even if the script is in the path. The only time it doesn't is if I specify a relative path from the command line. An option could be to check, if it doesn't match the full path, if $0 and the pwd eq what you're looking for.

Since I can't edit SOPW posts... :) what I need is the command that was called, including the directory of it... - Ant - Some of my best work - Fish Dinner	[reply]

I assume that $0 is set by the shell, not by the OS... I have RH 7.1 with bash and I get exactly what was typed to run the command... i.e. foo ./foo /usr/bin/foo etc... - Ant - Some of my best work - Fish Dinner	[reply]

wierd.. I have RH 7.1 with bash (perl 5.61). Here's my test `#!/usr/bin/perl -w print " I was called as $0\n";` [download] results as follows. tt is the original file. rr is a symlink in /usr/local/bin `[xxxx@yyy:/home/xxxx]$ tt I was called as ./tt [xxxx@yyy:/home/xxxx]$ rr I was called as /usr/local/bin/rr [xxxx@yyy:/home/xxxx]$` [download]	[reply] [d/l] [select]

My bad... I was assuming perl's $0 and c's `argv[0]` were the same, which they are not... $0 does have exactly what I want, thanks... - Ant - Some of my best work - Fish Dinner	[reply] [d/l]
