* misc: update --help content againRuediger Meier2017-06-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We change -h, --help display this help and exit -V, --version output version information and exit to -h, --help display this help -V, --version print version Some thoughts about this: * use "display" for --help because it matches better if we would add pager support (like git --help) * "print" for --version to be different * "this" for --help is important to make clear that running --help would not give you any better information than the one you see already * remove "information and exit" because it's bloat for the short-help, everybody knows what it does if it exists In the manpages we should use the old, longer but more correct descriptions, inclusive a reminder if --help/--version are only working when used as the only option. Note the term "version information" indicates that we don't only print a single version number. CC: J William Piggott <elseifthen@gmx.com> Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>
* misc: introduce print_usage_help_options()Ruediger Meier2017-06-271-2/+12
| | | | | | | | | | | | Consolidate --help and --version descriptions. We are now able to align them to the other options. We changed include/c.h. The rest of this patch was generated by sed, plus manually setting the right alignment numbers. We do not change anything but white spaces in the --help output.

* misc: revert to the old USAGE_HELP stringsRuediger Meier2017-06-261-2/+2
| | | | | | | | | | | | | | This reverts the include/c.h part of cc7cb070. As discussed on ml. Our current strings are imported from coreutils and not too bad. Also the old strings are still hardcoded at many places. So let's revert the change, then consolidate these strings really everywhere and then think again whether and how we should change them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no eloquent way to exclude/include arch dependent arguments from the ul_excl_t array. So when an arch dependent argument is left undefined err_exclusive_options() was printing out-of-bounds values. This commit cause them to be skipped instead. err_exclusive_options() shouldn't be printing out-of-bounds values in any case. Also change the error massage from 'options' to 'arguments' as some programs, like hwclock, distinguish between options and functions. Signed-off-by: J William Piggott <elseifthen@gmx.com>
* | libfdisk: fix NLS supportKarel Zak2017-04-251-2/+12
|/ | | | | | | | | | | | | | | | | | | The current libfdisk code uses gettext() to translate strings. It means it follows the default text domain (as set by textdomain(3) usually in the main program). This is useless for public shared library. We have call private bindtextdomain() and use dgettext() with private domain name to be independent on the main program. For this purpose include/nls.h supports UL_TEXTDOMAIN_EXPLICIT to use dgettext(). Note that libfdisk will continue to use util-linux.po, rather than keep the texts in the separate file. The nls.h has to be included only from fdiskP.h to be sure that nls.h works as expected for the library. Signed-off-by: Karel Zak <kzak@redhat.com>
* agetty: fix characters reorder in login promptKarel Zak2017-03-271-0/+4
| | | | | | | | | | | | | | The current agetty uses TIOCSTI ioctl to return already read chars from login name back to the terminal (without read() before tcsetattr() we will lost data already written by user). The ioctl based solution is fragile due to race -- we can return chars when terminal already contains another new chars. The result is reordered chars in login name. The solution is to use extra buffer for already read data. Reported-by: Michael Tretter <m.tretter@pengutronix.de> Signed-off-by: Karel Zak <kzak@redhat.com>
