see man page, or here: http://www.qnx.com/developers/docs/q...g_chkfsys.html
chkfsys will return nonzero in case of problems.

you need to use $ in your test command:
if test $STATUS -ne 0

If you know how to use the chkfsys utility, then you should know what it returns...especially since the man page TELLS YOU.
This is your script...YOU made the decisions however you'd like. Check the return code, and act on whatever you find.
You know by CHECKING THE OUTPUT of the command you ran
...which is VERY similar to your other thread:
http://www.linuxquestions.org/questi...em-4175511911/

You're getting "not found", because you just put "chkfsys" in your script, probably. Try putting the whole path into the script...and again, reading the bash scripting tutorials wouldn't be a bad idea.

hi ,
i have one question,

can mount the corrupted filesystem partition?

Since it's CORRUPTED, obviously not. Please see any of your other numerous threads about partitions for more hints to help you get going.
