Please ignore my bug report. I forgot that I was using the nonstandard
version of grep that was installed on the vice packs. My bug report
was this, for the sake of the people who didn't see it:
grep -i doesn't match upper-case letters in pattern to lower-case
letters in the input.
**=> soup:/mit/qjb <=**
% echo "This line contains the letter Q." | grep -i q
This line contains the letter Q.
**=> soup:/mit/qjb <=**
% echo "This line contains the letter q." | grep -i Q
Done echo This line contains the letter q. |
Exit 1 grep -i Q
Exact matches work correctly.
This feature works file on /usr/ucb/grep that is on the 6.0B packs
for both the RT and the VAX, but /bin/grep does not. Why do we
have two versions of grep in the standard execute path? /bin/grep
(according to the sources) does not even support the -i option.
All it does is increment the variable yflag which is not referenced
anywhere else in the program.
The NOTE file on vice does mention that /usr/ucb/grep is a symlink to
/bin/grep because of a different error that occured. Perhaps this
shouldn't have been done.
