Original diff by and OK naddy@
2018-12-10correct inaccurate and misplaced information in CAVEATSIngo Schwarze
and move it in part to the DESCRIPTION, in part to STANDARDS; triggered by a loosely related bug report from Lars dot Nooden at gmail dot com; OK jmc@, and no opposition when shown on bugs@
2018-12-08revert previous, it breaks regress and the llvm, gtk+2, and gtk+3 portsIngo Schwarze
because it changes the behaviour for empty input files; revert requested by naddy@ and sthen@
2018-12-07As an extension to POSIX, for consistency with our behaviour forIngo Schwarze
the "b" and "t" commands with a label, and for compatibility with GNU sed, also accept ";" followed by another command after "b" and "t" commands without a label: branch to the end of the script instead of erroring out. Parsing is unchanged. Missing feature reported by Lars dot Nooden at gmail dot com on bugs@. OK martijn@ millert@
2018-12-06Add support for "-" as an input file for stdin as per POSIX.Martijn van Duren
Simplify the code by allowing usage of stdin with the -i flag by pushing the result to stdout, so filters and in place editing can be combined. OK millert@
2018-11-14Make sed's -i flag more compatible with what gsed does.Martijn van Duren
- Reset the hold-space in between files - quit the editor as soon as a 'q' command is found - Make sure the temp-file is written back to the original file if we quit the editor temp-file not written back issue found by Time Chase. Lots of feedback from millert@ and schwarze@ OK millert@
2018-08-14Improve consistency of the substitution command further.Ingo Schwarze
When the opening square bracket ('[') is abused as the delimiter, the regular expression contains a bracket expression, and the bracket expression contains another opening square bracket (sick! - i mean, sic!), then do not require escaping that innermost bracket and treat a preceding backslash as a literal backslash character, in accordance with POSIX: $ printf 'x[x\\x\n' | sed 's[\[[][R[g' xRx\x $ printf 'x[x\\x\n' | sed 's[\[\[][R[g' xRxRx While here, also make the implementation more readable and insert some comments. Joint work with martijn@ (started during g2k18) and OK martijn@.
2018-07-11Make the output of the list command more sensible for the output device.Martijn van Duren
We now output $COLUMNS - 8 characters of the string and a newline. This is similar to the behaviour in ed(1). Discussed with and OK schwarze@
2018-07-11Rephrase the wording on the replacement string of the substitute command.Martijn van Duren
Cover more cases with less wording. Joint work with schwarze@ OK millert@
2018-07-10Disentangle the "SED ADDRESSES", "SED REGULAR EXPRESSIONS",Ingo Schwarze
and "s/// command" sections and clarify what an escaped delimiter does inside regular expressions and inside character classes. Joint work with martijn@, no objection from jmc@.
2018-07-09When using '[' as the delimiter in sed(1) s/// (don't do that, of course)Ingo Schwarze
and then including '[' in the regular expression by prepending a backslash to it, remove the backslash before feeding the RE to the RE engine, just like we already do it for other special characters like .^$*+?{(|. This makes sed 's[\[xy][...[' treat the xy thingy as a char class. Joint work with martijn@, OK guenther@ martijn@
2017-12-19Remove EXAMPLES section.Martijn van Duren
The example itself was taken directly from the POSIX specification by jmc@, who doesn't remember adding it. This example isn't very clear about what it actually does, so just remove it. If someone can come up with one or more examples that give a more clear introduction to the workings of sed feel free to send them in. Prompted by a diff by kshe59 <at> zoho <dot> eu OK jmc@

2017-12-12Fix 2 bugs introduced by previous.Martijn van Duren
Pointed out by kshe59 <at> zoho <dot> eu OK millert@
2017-12-11Fix and change y command in the following ways:Martijn van Duren
- When 'n' is used as a delimiter escaping 'n' will remain a newline instead of becoming a 'n' character. This is how POSIX specifies how this should work. Other implementations tested also do this wrong. - '[' and maybe other characters are not special during the parsing of the y command and don't need to be matched or treated special in any way. - POSIX specifies that a backslash followed by anything other than the delimiter, 'n', and another backslash, as well as repeating characters in string1 are unspecified. Since the various implementations handle these situations in opposing ways choose to error out on them to prevent people falling into the pitfall of expecting identical behaviour on various implementations. Inspired by the sed.1 patch by kshe59 <at> zoho <dot> eu Feedback and OK millert@ Manpage bits OK jmc@
2017-12-08Make the r command filename obligatory, similar to what FreeBSD and NetBSDMartijn van Duren
do for several years. While here make corresponding error message for missing read and write file consistent between commands/flag, and shrink the the code of the w flag of the s command by making it use the same code as the w command. Prompted by a larger diff by kshe59 <at> zoho <dot> eu OK millert@
2017-12-07Make the command formatting more consistent.Martijn van Duren
s/with/width type-O fix while here. From kshe59 <at> zoho <dot> eu OK jmc@
2017-08-01Apply stricter pledge rules if possible. These are based on the usage ofMartijn van Duren
the 'w' and 'r' functions and the 'w' flag to the 's' function. If non of the above is used and input is being read from stdin, we drop all the way down to stdio! Original inspiration by benno@. OK millert@

2016-03-17Switch (non-curses, non-ksh) programs that use COLUMNS to a single idiom.Anthony J. Bentley

2015-10-10normalize the ordering of tame requests (particularily, "rpath wpath cpath",Theo de Raadt
which i have put in that order). this is not important, but helps look for outliers which might be strange. it hints that "ioctl" should be reassessed in a few places, to see if "tty" is better; that "unix" may be used in some places where "route" could now work.
2015-10-09Change all tame callers to namechange to pledge(2).Theo de Raadt
2015-10-03sed only works on files, so the obvious goal is to remove it's networkTheo de Raadt
access in case it is exploited. tame with "stdio wpath rpath cpath" seesms to covers all usage cases, except -i performs a fchmod() on the in-place file, so conditionally also needs "fattr". ok sthen
