Question

Is there anyway you can do regex match group using sed like java regex pattern/match/group?

if i have string like

test-artifact-201251-balbal-0.1-SNAPSHOT.jar

how do I use sed just to get the result like:

test-artifact-0.1-SNASHOT.jar

I am wondering does sed allow you to do something like java regex, you define the pattern like:

([a-z]*-[a-z]*-)([0-9]*-)([a-z]*-)([.]*SNAPSHOT.jar)

and then you can get the results as an array like:

test-artifact-
201251-
balbal-
0.1-SNAPSHOT.jar

Answer 1

You have to escape parentheses to group expressions:

\([a-z]*-[a-z]*-\)\([0-9]*-\)\([a-z]*-\)\([.]*SNAPSHOT.jar\)

And use them with \1, \2, etc.

EDIT: Also note just before SNAPSHOT that [.] will not match. Inside brackets . is literal. It should be [0-9.-]*
