Given a filename in the form
someletters_12345_moreleters.ext, I want to extract the 5 digits and put them into a variable.
So to emphasize the point, I have a filename with x number of characters then a five digit sequence surrounded by a single underscore on either side then another set of x number of characters. I want to take the 5 digit number and put that into a variable.
I am very interested in the number of different ways that this can be accomplished.
echo 'someletters_12345_moreleters.ext' | cut -d'_' -f 2
INPUT='someletters_12345_moreleters.ext' SUBSTRING=$(echo $INPUT| cut -d'_' -f 2) echo $SUBSTRING
