[SOLVED] How to extract jira ticket number with sed?

Issue

I want to extract Jira ticket number from the branch name with sed. This is what I have

echo "PTW-123-branch-name" | sed 's/.*\([A-Z]+-[0-9]+[^-]\).*/\1/'

expected result: PTW-123

What is wrong with the regexp?

Solution

You may use this sed:

echo "PTW-123-branch-name" | sed 's/\([0-9]\)-.*$/\1/'

PTW-123

Details:

• \([0-9]\)-: Matches a digit and captures it in group #1 followed by hyphen
• .*$: Match remaining string until end
• \1: Is replacement that puts captured digit back in output

Alternatively you can use cut also:

echo "PTW-123-branch-name" | cut -d- -f1,2

PTW-123
