https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=223524 Bug ID: 223524 Summary: whatis 'c++' fails with regex error Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: wosch@FreeBSD.org The manual page of whatis(1) claims that the search is by default “case-insensitive substring matching” By default, apropos searches for makewhatis(8) databases in the default paths stipulated by man(1) and uses case-insensitive substring matching (the = operator) over manual names and descriptions whatis is a synonym for apropos -f. -f Search for all words in expression in manual page names only. The search is case insensitive and matches whole words only. In this mode, macro keys, comparison operators, and logical operators are not available. But when I tried to search for the term “c++” I get an regcomp error: $ whatis 'c++' whatis: regcomp /[[:<:]]c++[[:>:]]/: repetition-operator operand invalid whatis: ignoring trailing c++ usage: whatis [-afk] [-C file] [-M path] [-m path] [-O outkey] [-S arch] [-s section] name ... Quoting the plus character returns zero results: $ whatis 'c\+\+' whatis: nothing appropriate Using a single plus gives some results: $ whatis 'c+' c++filt(1) - decode C++ symbols -- You are receiving this mail because: You are the assignee for the bug.help
