[LTP] [PATCH 1/1] tst_test.sh: Add test cmd helper tst_test_cmds()

[Petr Vorel <pvorel@suse.cz>]

Hi,

> + tst_cmd_available()

> tst_test_cmds() is meant to be a check just for a particular test.
> Works like tst_check_cmds(), but instead of tst_brk() calls tst_res().

> tst_cmd_available() helper can handle cases when command shell builtin
> is not available (e.g. Busybox).

Pedantic version would check $? for 127 (indicating which itself it's not found).
Probably worth of adding it.

Kind regards,
Petr
