Hello all :)
I'm using coreutils 5.2.1 and I've noticed a weird behaviour of
'expr'. I don't know if it's my fault, but a command like:
$ expr "x" : "[:alpha:]"
returns 0 instead of 1, but a command like:
$ expr "x" : "[[:alpha:]]"
returns 1, correctly. That is, 'expr' understands character
classes but it needs that double bracket :( This is non portable
AFAIK, at least is not SUSv3 compliant regarding basic regular
expressions, and other binaries like 'tr' or 'grep' correctly use the
single bracket character classes.
Am I doing something wrong?
Thanks a lot in advance :)
