https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D226112 Warner Losh <imp@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Assignee|bugs@FreeBSD.org |imp@FreeBSD.org Status|Open |In Progress CC| |imp@FreeBSD.org --- Comment #5 from Warner Losh <imp@FreeBSD.org> --- This change isn't technically correct. Space is special, and that's not documented. What is done when a single character is not well documented. An input line is normally made up of fields separated by whitespace, or by the extended regular expression FS as described below. The fields = are denoted $1, $2, ..., while $0 refers to the entire line. If FS is nul= l, the input line is split into one field per character. However, this behavior is unspecified in the IEEE Std 1003.1 ("POSIX.1") standard. = If FS is a single space, then leading and trailing blank and newline characters are skipped. Fields are delimited by one or more blank or newline characters. A blank character is a space or a tab. If FS is a single character, other than space, fields are delimited by each single occurrence of that character. The FS variable defaults to a single space. is what I have in my tree to fix this paragraph. I'll commit it shortly aft= er waiting a week for feedback. --=20 You are receiving this mail because: You are the assignee for the bug.=
