string tokenizing

Shell Programming and Scripting
1

I have a string that looks like this:

blahblahblah_^substring^_blahblahblah

I need to extract substring, the bit between the ^ characters, into another string variable. This will be in a bash shell script.

Thanks.

echo "blahblahblah_^substring^_blahblahblah" | sed 's/.*_^\(.*\)^_.*/\1/'
3 
echo "$variable" | awk -F '^'  '{ print $2}'

You can also use parameter substitution.
