bak9

Creates a backup .bak copy of a file.

Usage

bak [OPTION]... FILE [DIR]

Creates a backup .bak copy of FILE.

If DIR is not specified, the copy is created in the same directory as FILE.

If multiple backups of FILE exist, the filename extension used will be: .bak.N.

With multiple backups, the most recent backup will be always bak.0. Previous copies will have their filename extension shifted by 1 (e.g., bak.1 -> bak.2).

Pruning (deletion) occurs after -n NUM backups.

If the current backup is no different than its predecessor, copying will be skipped.

Options

• -d
  Deletes all backup files for the source FILE.

• -n NUM
  Creates at most NUM backup files.
  If not specified, defaults to 10 (0-9).
