Network setting environment variables ???

Hello,

I want to set some environment variables with this script:

ip=$@
echo Remote Computer: $ip
PERLDB_OPTS="CallKomodo=$ip:9000 RemotePort=$ip:9010 PrintRet=0"
export PERLDB_OPTS
PERL5LIB=/opt/komodo
export PERL5LIB
echo PERLDB_OPTS: $PERLDB_OPTS
echo PERL5LIB: $PERL5LIB

But it does not work. For example "echo $PERL5LIB" just does return nothing (after executing the script, of course). What am I doing wrong???

You are executing the script which creates a child process - the child process has the variable set.

To get it in the Parent do the following for the appropriate shell subsitute myscript with the appropriate name of your script

sh and ksh
% . ./myscript

csh
$ source ./myscript

Data

yes this works, thank you. But there is another problem: the argument to the script (value of $ip) does not appear in the environment variable. What could the reason for this be?

Data script argument

Hello,

I want to execute a script which set some environment variables: ". ./script argument1". The environment variables are being set, but argument1 is being ignored. Why is this???


#!/bin/sh
ip=$1
echo Remote Computer: $ip
PERLDB_OPTS="CallKomodo=$ip:9000 RemotePort=$ip:9010 PrintRet=0"
export PERLDB_OPTS
PERL5LIB=/opt/komodo
export PERL5LIB
echo PERLDB_OPTS: $PERLDB_OPTS
echo PERL5LIB: $PERL5LIB

You are using the old Bourne shell and that's just the way it works. I guess that only Steve Bourne himself could tell you why.

ksh will work the way you want. Maybe you should switch shells?
