I should have tested a bit more.
[EMAIL PROTECTED] ~ $ echo 'a -lbcd' | grep -- '-l'
a -lbcd
[EMAIL PROTECTED] ~ $ echo 'a -lbcd' | grep -- '\b-l'
[EMAIL PROTECTED] ~ $ echo 'a lbcd' | grep -- '\bl'
a lbcd
It's the "-" that is not a part of a word. Any ideas? I guess the "\b"
after ${libname} is fine, but the one before the "-" is not. It's down
to [[:space:]]-l${libname}\b it seems. And hopefully there won't be any
any lines starting with "-l", or any "-llib" being quoted which is legal
but unmatchable. Ah, cannot grep be told that "-" is a valid "word"
symbol.
The only reason the script currently works is because:
grep '\b-l[[:alnum:]].*\b' ${1}
matches the "-l" in x86_64-pc-linux-gnu-gcc
You also do not need the ".*\b" in the above. The ".*\b" would always
match until the last word on the line (grep doesn't do greedy wildcard
matching), and since it would *always* match, there is no need in
matching at all.
