Hello all,
Hello,
Any time I run a unix command where I initiate a variable > use the

---------------------------------------
./test.1.pl
Use of uninitialized value in concatenation (.) or string at ./test.
1.pl line 8.
sh: syntax error at line 1: `|' unexpected

-----Here is the contents of the perl script--------
#!/usr/bin/perl -w
The first three lines *should* be:
#!/usr/bin/perl
use warnings;
use strict;
check_LANon () ;
You call the subroutine check_LANon() but you haven't assigned anything
to $utadm_l yet.
$utadm_l = "/opt/SUNWut/sbin/utadm -l" ;
sub check_LANon {
$LANstat = system(" $utadm_l | grep On") ;
What information did you expect that system() would return?
print "$LANstat\n" ;
}
------------------------------------------------------------
How can I run this succesfuly? I have other scripts that I need to do
this with as well, but I can't since I always get this error. If I
substitute $utadm_l with the actual command, it works fine. Only
barfs when I use a variable.
