Package: mawk
Version: 1.3.4.20240905-1
Severity: normal
X-Debbugs-Cc: [email protected]
Hello,
following up on a thread in #debian-devel:
mawk(1) claims to support the same regex syntax as grep -E, however the
behaviour of regexes involving {n,m} is different/strange.
$ printf '%s\n' 'x' 'xxx' 'xx' 'xxxx'| mawk '/^x{2,3}$/'
xx
$ printf '%s\n' 'x' 'xxx' 'xx' 'xxxx'| grep -E '^x{2,3}$'
xxx
xx
I would have expected that the output of both commands is identical (and
includes "xxx" as grep does).
Best regards
Uwe

This bug is fixed since mawk/1.3.4.20250131-1.
