When this script runs, it backs up the current $profile_target to
$profile_target$PROFILE_BACKUP_SUFFIX. This backup file already exists, though.
I back up shell profile/rc scripts before I add Nix to them.
I need to back up $profile_target to $profile_target$PROFILE_BACKUP_SUFFIX,
but the latter already exists.
Please follow these instructions to clean up the old backup file:
Here's how to clean up the old backup file:
1. Copy $profile_target and $profile_target$PROFILE_BACKUP_SUFFIX to another place, just
in case.
1. Back up (copy) $profile_target and $profile_target$PROFILE_BACKUP_SUFFIX
to another location, just in case.
2. Take care to make sure that $profile_target$PROFILE_BACKUP_SUFFIX doesn't look like
it has anything nix-related in it. If it does, something is probably
quite wrong. Please open an issue or get in touch immediately.
2. Ensure $profile_target$PROFILE_BACKUP_SUFFIX does not have anything
Nix-related in it. If it does, something is probably quite
wrong. Please open an issue or get in touch immediately.
3. Once you confirm $profile_target is backed up and doesn't already
mention Nix, replace it with $profile_target$PROFILE_BACKUP_SUFFIX.
