This is now fixed by the less-392. man page now states that: The pattern is a regular expression, as recognized by the regular expression library supplied by your system. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040506 Epiphany/1.2.4 Description of problem: Less(1) claims to be ed(1) compatible in the man page, as one would expect from most Unix utilites except for Awk, Egrep, Perl, etc., but in Less + is used as a metacharacter unescaped, so matching a literal + requires the pattern be \+. This is the opposite of ed, and is rather confusing. Version-Release number of selected component (if applicable): less-382-3 How reproducible: Always Steps to Reproduce: 1. man bash 2. /:+ Actual Results: Taken to the first instance of the literal ":" in the bash(1) manual page (the "OPTIONS" section). Expected Results: Taken to the first instance of the literal ":+" in the bash(1) manual page (the "Use Alternate Value" section). Additional info: A quick look at the Less home page suggests it plugs into many different regex libraries. It looks like the version of Less distributed with Red Hat/Fedora uses enhanced regular expressions rather than basic regular expressions. If this is the case, the manual page must be updated to reflect this.
