Help with Copy Shell Script
Hello,

I am currently learning UNIX scripting and have written a simple copy program.

However, upon execution, it returns an error despite debugging correctly.

Can anyone assist in explaining this?

Attached screenshots illustrating a test execution.

Many thanks.

Replace the following
Code:
if [ -e "$to" ]
.........
fi
cp $from $to

with
Code:
if [ -e "$to" ]; then
   echo "$to aready exists: overwrite (yes/no)?"
      read answer
         if [ $answer = yes ]; then
            echo "1"
            cp "$from" "$to"
         else
            echo "2"
            echo "Copy not performed"
         fi
else
   echo "3"
   cp "$from" "$to"
fi

Remove the echo statements if it works for you

Copy Shell Script still not functioning as expected
Hi Xbin,

Many thanks for the suggested code amendment.

I tried it but the existence test still seems to require an argument for some unknown reason.

Attached the test against the amended code.

Any further ideas much appreciated.

cp command should be like this..

Code:
cp /soucre_path/file /destination_path/

And what prevents one from doing that? You can always copy a file to another and cp allows that. That's the most basic usage of cp. Consult your man page.
