Shell Programming and Scripting

Hi All
I got stuck in an issue, and i want help from you guys. The issue is-:
I have two scripts one is call.sh(written in Unix) and another one is called.pl(written in Perl). What i do is i invoke the script call.sh and inside of call.sh the Perl script is called called.pl.

There is some calculations takes place in Unix script (call.sh) when it is executed and result of the calculations is assigned to a variable x (the value assigned to x is of integer type), I want to use this value(x) in my Perl script(called.pl), How can i export the value from Unix to Perl.

Please help me about this matter.

It can be achieved by passing as argument or by exporting the variable. Below is the example.
Passing as an argument:
call.sh:

Code:

x="argument"
# pass your value as argument to perl script
perl called.pl $x

called.pl:

Code:

#Here you can read the passed argument values.
#ARGV[0] for first argument
$x=$ARGV[0];
print "Passed value $x";

Exporting the variable:
code.csh

Code:

#export the variable u needed in perl script. I believe it should be set not export in csh.
export x="argument"
perl called.pl

called.pl:
Here you can read the exported variables.

Code:

print "Exported variable $ENV{x}";

Thanks,
Kalai

Code:

 
/path/of/called.pl "$x"

inside the perl script, you can get the $x by

Code:

 
my $x = $ARGV[0];

@parthmittal2007: Why don't you write the whole thing in Perl?

That i have to think earlier. I recently started to learn Perl
