NAME¶

sccs-branch - create a new branch and retrieve a version for editing

SYNOPSIS¶

sccs branch [options] [file1 .. filen]

DESCRIPTION¶

The branch subcommand creates a new branch and retrieve a version for editing. Except for creating a new branch, this is equivalent to the edit subcommand.

sccs branch is equivalent to ``get -b -e'' followed by ``delta -s -n'' followed by ``get -e -t -g''.

OPTIONS¶

-asequence

Retrieves the version corresponding to the indicated delta sequence number. This option is used primarily by the SCCS comb command (see sccs-comb(1)). For users, -r is an easier way to specify a version. The -a option supersedes the -r option when both are used.

-c date-time

-cdate-time

Retrieves the latest version checked in prior to the date and time indicated by the date-time argument. date-time takes the form:

yy[mm[dd[ hh[mm[ss]]]]]

Units omitted from the indicated date and time default to their maximum possible values; that is -c7502 is equivalent to -c750228235959. Values of yy in the range 69−99 refer to the twentieth century. Values in the range 00−68 refer to the twenty-first century. Any number of non-numeric characters may separate the various 2 digit components. If white-space characters occur, the date-time specification must be quoted.

A date-time specification in the form:

yyyy/[mm[dd[hh[mm[ss]]]]]

refers to a 4-digit year and allows one to specify a year outside the range 1969−2068.

-i sid-list

-isid-list

Specifies a list of deltas to include in the retrieved version. The included deltas are noted in the standard output message. sid-list is a comma-separated list of SIDs. To specify a range of deltas, use a `−' separator instead of a comma, between two SIDs in the list.

-l

Retrieve a summary of the delta table as l.file.

-p

Writes the retrieved version to stdout.

-s

Suppresses all output normally written on the standard output. However, fatal error messages (which always go to the standard error) remain unaffected.

-r[sid]

Retrieves the version corresponding to the indicated SID (delta).

The SID for a given delta is a number, in Dewey decimal format, composed of two or four fields: the release and level fields, and for branch deltas, the branch and sequence fields. For instance, if 1.2 is the SID, 1 is the release, and 2 is the level number. If 1.2.3.4 is the SID, 3 is the branch and 4 is the sequence number.

You need not specify the entire SID to retrieve a version with get. When you omit -r altogether, or when you omit both release and level, get normally retrieves the highest release and level. If the d flag is set to an SID in the s.file and you omit the SID, get retrieves the default version indicated by that flag.

When you specify a release but omit the level, get retrieves the highest level in that release. If that release does not exist, get retrieves highest level from the next-highest existing release.

Similarly with branches, if you specify a release, level and branch, get retrieves the highest sequence in that branch.

-x sid-list

-x[sid-list]

Excludes the indicated deltas from the retrieved version. The excluded deltas are noted in the standard output message. sid-list is a comma-separated list of SIDs. To specify a range of deltas, use a `−' separator instead of a comma, between two SIDs in the list.

EXAMPLES¶

To create a new branch for the file xec.c in the current directory, call:

sccs branch xec.c

ENVIRONMENT VARIABLES¶

See environ(7) for descriptions of the following environment variables that affect the execution of sccs-branch(1): LANG, LC_ALL, LC_CTYPE, LC_MESSAGES, and NLSPATH.

SCCS_NO_HELP

If set, sccs branch will not automatically call help(1) with the SCCS error code in order to print a more helpful error message. Scripts that depend on the exact error messages of SCCS commands should set the environment variable SCCS_NO_HELP and set LC_ALL=C.
