Dear All
I hava a questions as following
Write a shell script program called 'safecopy' that takes two filenames
(file1 and file2) as arguments. If file2 exists and file2 is a file that can
be written to, then the user should be warned and asked for permission to
proceed. Otherwise the file should be copied without any further interaction
with the user.

Thanks in advance

Try "man cp" and "man bash". They should help you a bit more.
To check if a file exists:
if [ -e $2 ]
To copy a file without user interaction:
cp -f $1 $2
I'm not gonna do your homework assignment. And I'm sure you can figure out the rest.
