## delta

    delta [options] files

Incorporate changes (add a delta) to one or more SCCS `files`. delta is used to store changes made to a text file that was retrieved by get -e and then edited. delta normally removes the text file.

### Options

-g`list`

  Ignore deltas whose SCCS IDs (version numbers) are specified in the comma-separated `list`. Use - to supply a range; e.g., 1.3,2.1-2.5.

-m[`list`]

  Supply a `list` of modification request numbers as reasons for creating new deltas. -m is useful only when admin has set the v flag for `file`. If -m is omitted, the terminal displays MRs? as an input prompt.

-n

  Do not remove the edited file (extracted by get -e) after execution of delta.

-p

  Print a diff-style listing of delta changes to `file`.

-r`SID`

  Delta version number that identifies `file`. -r is needed only when more than one version of an SCCS file is being edited simultaneously.

-s

  Suppress printing of new SID and other delta information.

-y[`string`]

  Insert `string` as a comment describing why the delta was made. If -y is omitted, the terminal displays comments? as an input prompt.
