Subject: bug#31816: Saved Sub String Only Saves Last
Date: Wed, 13 Jun 2018 13:03:16 -0400

[Message part 1 (text/plain, inline)]

If I use a saved substring it should capture the maximum number of
characters that fit the pattern, in this case  [0-9][0-9]*.

echo "I'm 2254 years old"|sed "s/^..*\([0-9][0-9]*\) /She's \1 /"
She's 4 years old"


She should be 2254 years old.

It does search correctly because without the substring it replaces all the
digits:

echo "I'm 2287 years old"|sed "s/^..*[0-9][0-9]*/She's many/"
She's many years old"
