Hi All; I've been trying to write a sed function to return only a numeric portion of a string, but can't seem to get it working. The input is a single string of letters and numbers, with the numbers always consecutive. For example: BUILD-AM005-a
I want to get the 005 out of this string.
echo BUILD-AM005-a | sed 's/.*([[:digit:]]).*/\1/g'
will return the digit 5. This is good!
So I add an asterisk to try to match multiple digits like: echo BUILD-AM005-a | sed 's/.*([[:digit:]]*).*/\1/g'
and instead of returning 005, it doesn't match anything, so returns nothing.
Can any of you RE maters help me out?
