I should have tested a bit more. |
| 14 |
|
| 15 |
chutz@lion ~ $ echo 'a -lbcd' | grep -- '-l' |
| 16 |
a -lbcd |
| 17 |
chutz@lion ~ $ echo 'a -lbcd' | grep -- '\b-l' |
| 18 |
chutz@lion ~ $ echo 'a lbcd' | grep -- '\bl' |
| 19 |
a lbcd |

It's the "-" that is not a part of a word. Any ideas? I guess the "\b" |
| 22 |
after ${libname} is fine, but the one before the "-" is not. It's down |
| 23 |
to [[:space:]]-l${libname}\b it seems. And hopefully there won't be any |
| 24 |
any lines starting with "-l", or any "-llib" being quoted which is legal |
| 25 |
but unmatchable. Ah, cannot grep be told that "-" is a valid "word" |
| 26 |
symbol. |
| 27 |

The only reason the script currently works is because: |
| 29 |
|
| 30 |
grep '\b-l[[:alnum:]].*\b' ${1} |
| 31 |
|
| 32 |
matches the "-l" in x86_64-pc-linux-gnu-gcc |
| 33 |
|
| 34 |
You also do not need the ".*\b" in the above. The ".*\b" would always |
| 35 |
match until the last word on the line (grep doesn't do greedy wildcard |
| 36 |
matching), and since it would *always* match, there is no need in |
| 37 |
matching at all. |
