Hi ,

I am running this script

#!/usr/local/bin/perl
#
$day =`cat /tmp/currentape | grep "Media Label"`; # Cats the file and
searches it for Monday
if ($day = ~m/ MON /ix){ #if the day contains monday
print "Mondays tape\n $day\n"; #print it is mondays tape
} else {
print "Some other days tape\n"; #if the file does not conatin the label
monday, print some other days tape
}


But the output is :

> ./tapetest.sh
Mondays tape
4294967295


! first issue is its not the moday tape cause when i do the cat
/tmp/currentape | grep "Media Label" the output contains no MON
!! second is that the output of variable $day is in numbers ??

what am i doing wrong.. Thanks !

^^^

You've misplaced a space here. The result is that the = and ~ are taken as
two separate operators, as if you'd written this:

if ($day = ~($_ =~ m/ MON /ix)) { # do stuff...
}

The above takes the return value of the match, performs a bitwise complement
on it, then assigns the result to $day.

What you *meant* to write is this:

if ($day =~ m/ MON /ix) { # do stuff
}
