* Usually, -width Fl (which is 10n) is too wide and hence ugly.schwarze2020-01-161-3/+3
| | | | Change several instances, most of them to the usual -width Ds.
* Do not perform top-level sort when -c is used with a -k field.millert2019-12-301-2/+3
| | | | From Richard Ipsum
* More Version 1 AT&T UNIX history.schwarze2019-09-061-3/+3
| | | | | | This became possible because copies of the original v1 manuals have shown up on the Internet some time ago. Reminded by Sevan Janiyan <venture37 at geeklan dot co dot uk>.
* When system calls indicate an error they return -1, not some arbitraryderaadt2019-06-281-3/+3
| | | | | | value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.
* In manpages, don't escape apostrophes as \'; it's rarely what you want.bentley2019-06-021-5/+9
| | | | | Most of these are correct just as '. A few benefit from Ql or \(aq. But if in doubt, just use '.

* Cleanup:schwarze2019-05-155-144/+21
| | | | | | | | | | | | | | | Delete handling of LC_COLLATE (which has no effect) and delete support for non-ASCII single-byte encodings, allowing to replace the condition byte_sort == 1 with sort_mb_cur_max == 1. Since none of our single-byte character and string functions are locale dependent, also zap inspection of LC_CTYPE while here. For know, keep the code supporting multi-byte encodings even though it is very ugly, it cannot be reached right now, and we have no plans to enable it any time soon. OK millert@ tb@
* Delete tentacles of LC_NUMERIC support.schwarze2019-05-134-106/+9
| | | | | | Our libc doesn't support that now and won't in the future. Minus ~90 lines of code, no functional change. OK tb@

|
* For the -g flag, treat non-floating point keys as 0, similar to -n.millert2015-04-051-6/+18
| | | | | This makes "sort -gu" and "sort -nu" behave similarly and passes our sort regress tests.
* The -b flag should only apply when key fields are specified.millert2015-04-053-13/+24

| | | | | | | | | | | | | "sort -o file -c file" has unspecified behavior and would leave an empty file behind if it was sorted, the original file it was not. If -c (or -C) has been specified, only perform that action and ignore -o among other arguments. While at it, clean up check() internals. with input by and ok millert@
* If -S has been supplied multiple times, only take last one into account.tobias2015-04-031-4/+7

| | | | | | | Also make sure that the parsed memory amount, stored in a long long, won't be larger than SIZE_MAX to properly support 32 bit systems. with input by and ok millert@

* Block signals during tmp_files insertion, so that the signal handlerderaadt2015-04-011-1/+7
| | | | | | cannot encounter an incoherent list. It was an absolutely tiny signal race. ok millert

|
* Remove some unneeded NULL checks that don't really help anything.millert2015-04-011-130/+111
