I got "if: Expression syntax" error when I executed this simple
script. I have no idea what went wrong. please help. thanks!!

#!/bin/csh

I suggest

#!/bin/csh -f

This protected your script from interacting with the user's ~/.cshrc file


setenv SRCPATH /home/test
if (/usr/bin/ls $SRCPATH | wc -l > 0) then

You should always put spaces after brackets with csh.
And you can't use pipes where csh wants an expression.

And if you want to test for the existance of files in a directory, I'd use

if ( -d "$SRCPATH" ) then
set count = ( `ls "$SRCPATH" | wc -l` )
else
echo directory $SRCPATH missing
exit
endif

if ( $count > 0 ) then
echo great 0
else
echo less 0
endif
.
