Re: Call perl script and capture values in bash.

in reply to Call perl script and capture values in bash.

If you are not able to parse the output to find the variables (which should be possible - can you show an example values?), you can save each variable to its own file and then retrieve the values from the files.

Thank you for your fast reply! The perl script generates yesterdays date, saves it in $day $month and $year and prints these 3 variables. I can use this date as one string, that is no problem. But the perl script also has the variable $counter which is also printed. The final output looks like this:

print "Backup date: $day\.$month\.$year\n";
print "$counter files have been successfully saved.\n";

I need to use the date and the $counter value in bash.

Parse output like ...


print "counter=$counter files have been successfully saved.\n";

In bash capture value assign after "counter=" string..

You can save the output to a bash array to easily access the values:

out=($(script.pl))
date=${out[2]}
counter=${out[3]}

Thank you both, finally it works! :)
