Editing a ksh script > Please assist!
I am trying to edit a script that contains the following:

/DBA/general/sh/rman_backup.ksh -d PROD2 -l 1

I am trying to add a logic in the script such that if /DBA/general/sh/rman_backup.ksh does not exists, then the script would return an error code of 1. Otherwise, the script continues on.

Please assist.

Thanks!

Use the -e option of test to check the existance of the file, something like:

Code:
if [ -e /DBA/general/sh/rman_backup.ksh ]; then
  /DBA/general/sh/rman_backup.ksh -d PROD2 -l 1
else
  return 1
fi

Read the manpage of test.

I would test that the file exists and is executable i.e.
Code:
if [[ -x /DBA/general/sh/rman_backup.ksh ]]; then
    /DBA/general/sh/rman_backup.ksh -d PROD2 -l 1
else
    return 1
fi
