I just wanted to know how can I send variable that are set to bash script to Perl script. For Example
bash script
#!/bin/bash
var="bob"
perl perlscript.pl
return 0
so when the perlscript is launched I want to have bob in Perl script
#!/usr/bi/perl -w
print ""
ok after some reading the books I got this I think
#!/bin/bash
var="bob"
export var
perl perlscript.pl
and in perlscript.pl
#!/usr/bi/perl -w
my $var1 = $ENV{"var"};
print "\ $var1\n";
who knew book was actually more useful than internet
Since you want to access environment, you can use %ENV global hash,
print $ENV{var};
Might an easier way be to do the following...
Shell script
#!/bin/bash
var="bob"
perl perlscript.pl $var
Perl script
#!/usr/bin/perl
use strict;
my $var = shift; # reads first arg passed on command line
print "$var \n";
I suggest this as reading from the environment is ok but there is always a chance that you may read/write from/to an existing variable.
At least if you keep it to local shell script variables then you are in control of what is being passed into your Perl script.
