* misc: consolidate version printing and close_stdout()Karel Zak2019-04-161-3/+3
| | | | Signed-off-by: Karel Zak <kzak@redhat.com>
* setterm: fix --hbcolor descriptionJakub Wilk2019-03-081-1/+1
| | | | | | | --hbcolor is for half-bright characters, which is sort of opposite of bold. Signed-off-by: Jakub Wilk <jwilk@jwilk.net>
* setterm: update comments about -ulcolor/-hbcolor syntaxJakub Wilk2019-03-071-2/+2
| | | | Signed-off-by: Jakub Wilk <jwilk@jwilk.net>
* setterm: fix bright colors for --ulcolor/--hbcolorJakub Wilk2019-03-071-0/+3
| | | | | | | The "bright" keyword was parsed, but it didn't actually affect the color that was set. Signed-off-by: Jakub Wilk <jwilk@jwilk.net>
* setterm: disallow "default" for --ulcolor/--hbcolorJakub Wilk2019-03-071-1/+1
| | | | | | | Passing "default" to --ulcolor or --hbcolor worked, but it set the color to bright red. This was not a documented syntax, so let's forbid it. Signed-off-by: Jakub Wilk <jwilk@jwilk.net>

| | | | | | | | | changed in include/c.h and applied via sed: sed -i 's/fprintf.*\(USAGE_MAN_TAIL.*\)/printf(\1/' $(git ls-files -- "*.c") sed -i 's/print_usage_help_options\(.*\);/printf(USAGE_HELP_OPTIONS\1);/' $(git ls-files -- "*.c") Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>
* misc: consolidate all --help option descriptionsRuediger Meier2017-06-271-2/+3
| | | | | | | | Now we are always using the same text also for commands which had still hardcoded descriptions or where we can't use the standard print_usage_help_options macro. Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>

| | | | | | | | | | text-utils/tailf.c:69:21: warning: Using plain integer as NULL pointer Since many 'struct option' has used zero as NULL make them more readable in same go by reindenting, and using named argument requirements.

* Use --help suggestion on invalid optionKarel Zak2016-12-191-1/+1
| | | | | | | | The current default is to print all usage() output. This is overkill in many case. Addresses: https://github.com/karelzak/util-linux/issues/338 Signed-off-by: Karel Zak <kzak@redhat.com>

* setterm: correct usage() bright color argumentSami Kerola2014-05-191-14/+12Star
| | | | | | | This has been wrong since commit 2dc8716. The bright is a prefix attribute to other colors. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* setterm: make -msglevel 0 to work as is did earlierSami Kerola2014-05-191-5/+7
| | | | | | | | Commit 3393c136 caused regression. The klogctl() logging range is 1-8, but the value 0 is special according to setterm.1 manual page. It turns on loging, same way as '-msg on' option. Signed-off-by: Sami Kerola <kerolasa@iki.fi>

* setterm: remove usage comment segmentSami Kerola2014-05-191-46/+0Star
| | | | | | | | It is enough trouble to keep usage output aligned with getopt() parsing, manual page, and bash-completion, so get rid of the unnecessary effort duplication. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* setterm: move show_tabs() and screendump() functionsSami Kerola2014-05-191-95/+92Star
| | | | | | | Earlier the function was in the middle of option parsing code segment, and screendump() required function prototype. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* setterm: use string utils to numeric parsingSami Kerola2014-05-191-36/+25Star
| | | | | | | Check the input numbers are numbers, which makes also the code shorter, and user experience better as half invalid imputs will error. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* setterm: recommend long options with double hyphenSami Kerola2014-05-191-37/+37
| | | | | | | | While the -version style options will work for next unknown number of years start moving towards user interface that has way of invoking long options as most of the other commands. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* setterm: use getopt_long_only() for option parsingSami Kerola2014-05-191-490/+426Star
| | | | | | | | | | | | | | The getopt_long_only() has advantage of allowing one and two hyphen versions of options, for example -help and --help. Secondly the getopt function family from libc can ensure some options requiring arguments, while other are optional, and some should not accept argument at all. That makes option parsing more robust. Unfortunately retiring the old option parsing makes this change greater than preferred. Assuming not mistakes happen the new code works functionally exactly as the old did.

| | | | | | | Use klogctl(2) from sys/klog.h just like dmesg(1). The rest is just reordering, and indenting. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
