Shell script debugging

hi all

only the weirdest thing happened with me just now. I was debugging a shell script and I found that a step that was supposed to execute later was getting executed prior to another step for no reason. You know any ?

i mean have a look at the following command-
Code:
[if $DISPLAY xstatus | $GREP "$right...$right" ]

here it tries to grep first(and hence gives an ambiguous output) and later displays the xstatus.(It should do the opposite,right?)

also any idea what the command which frsh does ? it gives no output on my system. But it sure does something.

Your valuable inputs are always welcome

~cheers
