Shell Programming and Scripting

Hi,

I have an embedded Perl construct in a korn script. However, I cannot seem to access the shell variables that were declared outside this Perl section.

This is how my script is written....I have also tried back-ticks where I assign the shell variable to my local perl variable, still doesn't work.

#!/usr/ksh
shell_var1
shell_var2
..
some ksh code..
..
# perl section below...
perl <<-'EOF'
local $perl_variable1=${shell_var1}
..
some code
..
EOF
..
..

Please help. Thanks in advance!

Cheers,
Vit

Use the %ENV hash to access environment variables. Environment variables will not normally become Perl variables (unless you write some code to do so) magically. But note that, because perl is executed as a process, you cannot change the corresponding environment variable in the shell from Perl, because what you will get from Perl is just a copy:

Code:

$ ( export TEST="me"; perl -e 'print $ENV{"TEST"}, "\n"'; )
me
$ echo $0
ksh
