Try it out, place these lines in your script:

and call your script with 4 parameters like:
./scriptname par1 par2 par3 par4

Note that test -f file is successful only if file is a regular file, not a symbolic link.

Also, test -e file is successful for any file, even a symbolic link.

Also, test -s file is sometimes more helpful because it fails for empty (zero-length) files (but succeeds for symbolic links).

Rather than put the result in a variable with $?, the code might be easier to read if you do it in a structured way, like this:
if [ -s /usr/dat/xmit/file ]; then
    # Do your processing here

Note that the bracket, [, is the same as test.

Relates to FTP

Thnks to all.
I have one problem in my script.
in my script, i have below line of FTP code:
ftp -nv $server > $logfile <<END
 user $id $pwd
 put $fil1 $fil2

While i try to execute my script, it showing error like:
220  FTP server ready.
331 Password required for admin.
530 Login incorrect.
Login failed.
530 Please login with USER and PASS.
530 Please login with USER and PASS.
221 Goodbye.

If i give each line individually lik below,

$ user $id $pwd

then FTP is happening corectly. Can anyone plz tel me wats wrong in my first FTp step by which im unable to connect?
