Hi List,
While verifying the command grep and analysing/comparing the behavior
with GNU and busybox. I notices following
1. __-H__ and __-h__ options, we prefer -H over -h, GNU and Busybox prefer
the last one mentioned on command line.
2. links are not followed for doing grep, i.e. grep "search" <linkToFile or
Dir> -r
no results are shown. Shouldn't the link be followed.
3. searching in binary files, toybox gives very minimal or no results, e.g.
grep "toy" toybox_unstripped, reports 4-5 lines whereas GNU/BBox fills
the scroll buffer.
The spec http://pubs.opengroup.org/onlinepubs/9699919799/utilities/grep.html
doesn't mention anything for these behavior or options.
Do have a look and give your inputs on
What is the right one to be followed?
Thanks,
Ashwini
