I'm debugging a ksh script written by someone else that does the following:
It runs a command and redirects stdout to a file called dberror that already exists using ">". This command fails with the following error:
The file access permissions do not allow the specified action.
The script continues and a couple lines later it deletes the error file like this:
rm -f dberror
The file is successfully deleted but no file permissions are changed in the script.
My question is why the ">" operator can't overwrite the file but the rm -f can delete it? I always thought that anyone who has write permissions on the file could overwrite it with ">".

times(1) User Commands times(1)NAME
times - shell built-in function to report time usages of the current shell
SYNOPSIS
sh
times
ksh
times
DESCRIPTION
sh
Print the accumulated user and system times for processes run from the shell.
ksh
Print the accumulated user and system times for the shell and for processes run from the shell.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a
variable assignment. This means that tilde substitution is performed after the = sign and word splitting and file name genera-
tion are not performed.
