Bugs that need fixing as of Mon May 8 17:22:06 MDT 2000
|
||||
|
||||
- zcat option parsing broke (maybe replace zcat binary with a shell script?)
|
||||
- cp -fa doesn't work (-a option parsing probably overrides everything)
|
||||
- 'grep foo$ file' doesn't work
|
||||
- 'grep *foo file' segfaults
|
||||
- ps dirent race bug (need to stat the file before attempting chdir)
