delta(1)

LC_MESSAGES determines the language in which messages are displayed.

If LC_CTYPE or LC_MESSAGES is not speci®ed in the environment or is set to the empty string, the value of LANG is used as a default for each unspeci®ed or empty variable. If LANG is not speci®ed or is set to the empty string, a default of "C" (see lang(5)) is used instead of LANG. If any internationalization variable contains an invalid setting, delta behaves as if all internationalization variables are set to "C". See environ(5).

International Code Set Support

Single- and multi-byte character code sets are supported.

DIAGNOSTICS

Use sccshelp(1) for explanations.

WARNINGS

SCCS ®les can be any length, but the number of lines in the text ®le itself cannot exceed 99 999 lines.

Lines beginning with an ASCII SOH character (octal 001) cannot be placed in the SCCS ®le unless the SOH is escaped. This character has special meaning to SCCS (see sccs®le(4)) and will cause an error.

A get of many SCCS ®les, followed by a delta of those ®les, should be avoided when the get generates a large amount of data. Instead, multiple get/delta sequences should be used.

If the standard input (-) is speci®ed on the delta command line, the -m(if necessary) and -yoptions must also be present. Omission of these options causes an error.

Comments can be of multiple lines. The maximum length of the comment (total length of all comment lines) cannot exceed 1024 bytes. No line in a comment should have a length of more than 1000 bytes.

FILES

All of the auxiliary ®les listed below, except for the g-®le, are created in the same directory as the s-®le(see get(1)). The g-®leis created in the user's working directory.

g-file

Existed before the execution of delta; removed after completion of delta

 

(unless -nwas speci®ed).

p-file

Existed before the execution of delta; may exist after completion of delta.

q-file

Created during the execution of delta; removed after completion of delta.

x-file

Created during the execution of delta; renamed to SCCS ®le after completion of

 

delta.

z-file

Created during the execution of delta; removed during the execution of delta.

d-file

Created during the execution of delta; removed after completion of delta.

/usr/bin/bdiff

Program to compute differences between the ®le retrieved by get and the g-®le.
