Subject: substring extractionOS: Unix Bourne shellCPU/Ram: ?Model/Manufacturer: ?
Comment: I am trying to extract information from a string that is surrounded by parentheses:line="blahblah(important)" #no spaces
I thought something like echo ${line##(*)} would work but it doesn't. It just prints out the comlpete string.
Could anyone please help?

Reply: (edit )Probably, some regex expert can come up with a better solution, but this one works:#!/bin/ksh
line="blahblah(important) #no spaces"
newline=$(echo "$line" | cut -d\) -f1 | cut -d\( -f2) echo $newline

Reply: (edit )I don't do much shell scripting so I'll show the perl syntax...the key part is the regex.#!/usr/bin/perl -w
$line = q("blahblah(important) #no spaces");
print $1 if $line =~ /"(.+?)"/;
