I don't understand what point they're making either.

All you need to be is "professional". That is, before you edit a file, copy it (backup).

Quote:
cp existing existing.bck
That way if you make a lot of (bad) changes and you want to see what it was like before you started, no problem.

Also, never delete any file that you're not sure about. Yes, this is where mv comes in (as they suggest).
I think that I need to delete this configuration file..............

mv existing existing.old

Whoops......shouldn't have deleted that? No problem, mv it back.
NEVER delete anything you're not sure about.

If the system crashes whilst you're editing a file, no problem, you've got an original copy.

Just be professional and you won't go wrong.

edit-pr(1)                                                     GNATS User Utilities                                                     edit-pr(1)

NAME
edit-pr - edit a problem report in the GNATS database SYNOPSIS
edit-pr [ -h | --help ] [ -V | --version ] [ -d databasename | --database=databasename ] [ -H host | --host=host ] [ -P port | --port=port ] [ -v user | --user=user ] [ -w password | --passwd=password ] PR DESCRIPTION
edit-pr is used to make changes to existing PRs in a GNATS database. edit-pr first examines the PR and locks it if it is not already locked. This is to prevent a PR from being edited by two users simultane- ously. If the PR is already in the process of being edited, edit-pr displays the name of the person who owns the lock. edit-pr then calls $EDITOR on PR. After the PR has been edited, it is resubmitted to the database, and the index is updated. If you change a field that requires a reason for the change, edit-pr prompts you to supply a reason for the change. A message is then ap- pended to the Audit-Trail field of PR with the changed values and the change reason. Depending on how the database is configured, editing various fields in the PR may also cause mail to be sent concerning these changes. In the default configuration, any fields that generate Audit-Trail entries will cause a copy of the new Audit-Trail message to be sent. OPTIONS
-h, --help Prints a brief usage message for edit-pr. -V, --version Prints the version number for edit-pr. -d, --database Specifies the database containing the PR to be edited; if no database is specified, the database named default is assumed. This option overrides the database specified in the GNATSDB environment variable. GNATS network options: -H, --host Hostname of the GNATS server. -P, --port The port that the GNATS server runs on. -v, --username Username used to log into the GNATS server. -w, --passwd Password used to log into the GNATS server. ENVIRONMENT VARIABLES
The environment variable EDITOR specifies the editor to invoke on the PR. Default is vi(1). The GNATSDB environment variable is used to determine which database to use. For a local database, it contains the name of the database to access. For network access via gnatsd, it contains a colon-separated list of strings that describe the remote database, in the form server:port:databasename:username:password Any of the fields may be omitted, but at least one colon must appear; otherwise, the value is assumed to be the name of a local database. If GNATSDB is not set, it is assumed that the database is local and that its name is default. FILES
/tmp/ep$$ Temporary file for PR being edited. /tmp/ed_pr_ch$$ Holds Audit-Trail change message, if needed. /tmp/u$$ Holds output of lock function. SEE ALSO
