use DateTime gives error

pgmer6809 has asked for the wisdom of the Perl Monks concerning the following question:

This simple code

#/usr/bin/perl
#
use DateTime;
print "DateTime Loaded\n";
exit 77 ;
[download]

Works if I run: perl tst_useDT.pl But if I just type: ./tst_use_DT.pl I get an error:

./tst_use_DT.pl: line 3: use: command not found

Error: no such file "DateTime Loaded\n"

What could be wrong? I did install DateTime twice; once using sudo to /usr/local and once to my own home directory. Could that be the reason? If so how would I delete the module from my homedirectory? thanks, pgmer6809

You're missing an exclamation mark in the very first line, after `#`. Update: That's causing the shell to think it's a shell script instead of a `perl` script, and the first error message you're seeing is actually from the shell trying to run a program called `use`.	[reply] [d/l] [select]

I'm an idiot. It came to me as I was on the verge of sleep last night. I was hoping I could delete this before anyone noticed. :(! Thanks for the help. pgmer6809	[reply]
