Bug ID: 282143
Summary: grep -v does nothing
Product: Base System
Version: 13.4-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
grep(1) mentions -v to print only non-matching lines, but this seems not to be
implemented (with a quick look ath the source)
i.e: tail -F /var/log/maillog | grep manylines | grep -v without_this_pattern
doesn't print anything at all.
best regards
Daniel
