wiz 5739c48f68 Punctuation nits, drop unnecessary .Pps, sort sections. 2001-12-20 20:07:40 +00:00
wiz 242b959069 Don't xref set(1) and case(1), since they are builtins and we don't 
have separate man pages for them.
Xref passwd 5 instead of 4, environ 7 instead of 5, and comment out xref
to profile(4), which we don't have.
Improve markup of SYNOPSIS.
Some whitespace fixes while I'm here.

toddpw e08886d505 Correct {list;} example and fix formatting/typo in the operator lists. 2001-04-01 02:15:45 +00:00
wulf 8d23cb0373 Extended functionality of the trap builtin, which now closely follows 
POSIX recommendations.

	- trap now accepts signal names and signal numbers
	  e.g. INT, SIGINT, 2
	- added option -l that outputs a list of valid signals
	- added signal EXIT to list of valid signals
	- a `-' in the action part will reset specified signal to their
	  default behaviour
	- changed standard output format to make it suitable as an input
	  to another shell that achieves the same trapping results

garbled f33f4be925 Massive fixup: 
Rewrite man page in mandoc format rather than nasty man format.
Fix a ton of parsing errors, and generate proper .Xr's.
document all known environment variables.
suggest ksh rather than bash.

The last two fix PR #1966.  Wheee!

Somebody with access to the POSIX spec needs to go in here, and document
our adherence, or lack thereof.

kleink 3780e6aa5d Per 1003.2, the (builtin) read utility shall treat the backslash as an 
escape character (including line continuation), unless the `-r' option
is specified:
* adopt to this behaviour, add the `-r' option to disable it;
* remove the `-e' option, which was previously necessary to get this behaviour.
