** Bug fixes grep -i '^$' could exit 0 (i.e., report a match) in a multi-byte locale, even though there was no match, and the command generated no output. E.g., seq 2 | LC_ALL=en_US.utf8 grep -il '^$' would mistakenly print "(standard input)". Related, seq 9 | LC_ALL=en_US.utf8 grep -in '^$' would print "2:4:6:8:10:12:14:16" and exit 0. Now it prints nothing and exits with status of 1. [bug introduced in grep-2.6] 'grep' no longer falsely reports text files as being binary on file systems that compress contents or that store tiny contents in metadata. |
