* regularize format of source file headers, no code changesDenys Vlasenko2017-09-181-6/+6

* make 17 state-changing execing applets (ex: "nice PROG ARGS") noexecDenys Vlasenko2017-08-041-1/+1
| | | | | | | | | | | | | | | | | | | | The applets with "<applet> [opts] PROG ARGS" API very quickly exec another program, noexec is okay for them: chpst/envdir/envuidgid/softlimit/setuidgid chroot chrt ionice nice nohup setarch/linux32/linux64 taskset cttyhack "reset" and "sulogin" applets don't have this form, but also exec another program at once, thus made noexec too.

* cttyhack: handle multiple consoles found in sysfsAaro Koskinen2012-02-041-3/+10
| | | | | | | | | | | | If multiple consoles are found from the sysfs file, cttyhack fails: cttyhack: can't open '/dev/tty0 ttyS0': No such file or directory In such cases take the last one as the kernel will use that one for /dev/console.

* cttyhack: print detected ctty name when called without parametersAlexander Shishkin2011-10-311-34/+42
| | | | | | | | | | | | | Sometimes there's a need to figure out the controlling tty from a shell script, for example, to obtain a line for getty. In this case it's easier to call cttyhack than trying to repeat some of the cttyhack's logic. function old new delta cttyhack_main 283 327 +44 packed_usage 28911 28915 +4 Signed-off-by: Alexander Shishkin <virtuoso@slind.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
