I just compiled the new version and noticed a minor
error message during the build of the manpages:
GEN matches4.man
grep: invalid option -- o
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.
Looks like my grep version is too old.
I think it is ok to assume -o is always there. Nov 2001, that's linux
2.4.14 timeframe, and most of the now-ancient distros have gone at
least up to 2.4.20s, which should imply that they also updated their
greps.
Should ./configure detect that
or is it even possible to transform the grep call into something else?
I assume people would not be amused if we start requiring perl.
But you can use it as a workaround...
perl -ne 'print$&if/\b[A-Z0-9]+\b/'
What exactly is that grep supposed to do? How about sed
or awk?
