Re: passing a variable from shell script to the main perl

Just use backticks.

my $results = `shell.sh`;

Changes to your %ENV made by the shell script will not persist when you return to the perl script. Similarly, changes to the %ENV by your perl script will not stay when it ends either. Although there are "tricks" one can do in theory.

How are you calling your shell script? Are you using system? `system("shell.sh");` [download] Any changes that your shell.sh script makes to the `%ENV` will not stay after the system command is finished. Instead, simply have your shell.sh script echo some text that your perl script can capture when using backticks. my $results = `shell.sh`; if ($results =~ /Hello World/) { print "tada!"; } [download] shell.sh `echo "Hello world";` [download]	[reply] [d/l] [select]

<text>when I do this </test> $xx=`sh $translationscript $filename $source_dir $file 2>&1`; <text> the value $xx has the log from the shell script and the STDOUT. Also, in the shell, I am checking for some errors and based on the error - I have a variable defined and I want that variable need in perl and then I will have to continue my script based upon the type of error I get from the shell. How do I do this? </text> thx	[reply] [d/l]
