Shell Programming and Scripting

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

ls $SOLHOME/internalDisk/"$fn" 2> /dev/null | wc -l > cfn

What this does is redirect stderr from the `ls` command to /dev/null (bit bucket) =p

I have done the above commands but it gave me this Error Message:
Ambiguous output redirect

I also tried the following:

ls $SOLHOME/internalDisk/"$fn" | wc -l > cfn 2>&errors and gave the same error.

Check out this site. Apparently, you cannot do that!

Why not just use something like this?

Code:

set yourfile="/path/to/yourfile"
if (-e $yourfile) then
 # do something if it exist
else
 # do something if it does not exist
endif

Check the man page for csh for other options.

Thanks a lot gentlemen! I will try that!
