[LTP] [PATCH 1/2] tst_rod: Use args[0] as the command name

[Martin Doucha]

Using argv[1] as the command name might fail if the first argument happens
to be I/O redirection. Use args[0] which is always the first argument not
processed by tst_rod.

[LTP] [PATCH 2/2] tst_rod: Fail on directory change commands

[Martin Doucha]

Using tst_rod to check directory change success doesn't work. The command
gets executed in a subprocess and will have no effect on the parent
shell where the directory change is desired.

Beware that this patch will cause a lot of broken shell tests to fail.
Another patchset fixing the incorrect ROD usage in shell tests is needed
before merging this patch.

The only broken test I've found is du01.sh that does
"ROD_SILENT cd basedir" are there actually any other tests that does so?

I also wonder if we should care for pushd/popd which are bashism and should not
be used in LTP tests which use new shell API.

So far they are used in testcases/realtime/run.sh testscripts/test_realtime.sh,
which does not use shell API (and realtime should be removed after porting
anything useful to rt-tests).

Indeed it looks just du01.sh.

Kind regards,
Petr
