Below is a part of the script that I wrote when checking whether a file exist in the Internal Disk or not. If a file doesn't exist, how do you get rid of the error message "file or directory does not exist" to show up on screen? Instead, I wanted only the warning message "FILE DOES NOT EXIST IN INTERNAL DISK" that I have setup to appear? Please help me out. Thanks a lot!

#! /bin/csh -f
# fn = filename.
set fn = `cat fn`
#cfn = check filename if it exist in Internal disk.
set cfn = y
while ($cfn == y)
printf "\n\n\n\nEnter filename, `echo $fn` (default) or x (exit): "
set fn = $<

if ($fn == x) then
else
if ( $fn == "" ) then
set fn = `cat fn`
else
echo $fn > fn
endif

ls $SOLHOME/internalDisk/"$fn" | wc -l > cfn
clear

set cfn = `cat cfn`
if ( $cfn == 0 ) then
printf "\n\n\n\n%8s==================================================\n\n"
printf " "\""FILE "\"""$fn""\"" DOES NOT EXIST IN THE INTERNAL DISK\!"\"""
printf "\n\n%8s==================================================\n"
set cfn = y
#end1
end
else
endif
endif
