DESCRIPTION
The get utility retrieves a working copy from the SCCS his-
tory file, according to the specified options.For each s.filename argument, get displays the SCCS delta
ID (SID) and number of lines retrieved.If a directory name is used in place of the s.filename argu-
ment, the get command applies to all s.files in that direc-
tory. Unreadable s.files produce an error; processing con-
tinues with the next file (if any). The use of `-' as the
s.filename argument indicates that the names of files are to be read from the standard input, one s.file per line. The retrieved file normally has the same filename base asthe s.file, less the prefix, and is referred to as the g-
file.For each file processed, get responds (on the standard out-
put) with the SID being accessed, and with the number of lines retrieved from the s.file. OPTIONS The following options are supported:-asequence Retrieves the version
corresponding to the indicated delta sequence number. This option is used primarily by the SCCS comb command (seesccs-comb(1)). For users, -r
is an easier way to specify aSunOS 5.11 Last change: 2 Jul 2007 1

version. The -a option super-
sedes the -r option when both
are used.-b Creates a new branch. Used
with the -e option to indicate
that the new delta should have a SID in a new branch. Instead of incrementing the level forversion to be checked in, get
indicates in the p.file that the delta to be checked in should either initialize a new branch and sequence (if there is no existing branch at the current level), or increment the branch component of the SID. If the b flag is not set in the s.file, this option is ignored.-c date-time | -cdate-time Retrieves the latest version
checked in prior to the date and time indicated by thedate-time argument. date-time
takes the form: yy[mm[dd[ hh[mm[ss]]]]]Units omitted from the indi-
cated 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. Valuesin the range 00-68 refer to
the twenty-first century. Any
number of non-numeric charac-
ters can separate the various2 digit components. If white-
space characters occur, thedate-time specification must
be quoted.-e Retrieves a version for edit-
ing. With this option, get
places a lock on the s.file, so that no one else can checkSunOS 5.11 Last change: 2 Jul 2007 2

in changes to the version you have checked out. If the j flag is set in the s.file, thelock is advisory: get issues a
warning message. Concurrentuse of `get -e' for different
SIDs is allowed. However, get
does not check out a versionof the file if a writable ver-
sion is present in the direc-
tory. All SCCS file protec-
tions stored in the s.file, including the release ceiling, floor, and authorized userlist, are honored by `get -e'.
-g Gets the SCCS version ID,
without retrieving the version itself. Used to verify the existence of a particular SID.-Gnewname Uses newname as the name of
the retrieved version.-i sid-list | -isid-list Specifies a list of deltas to
include in the retrieved ver-
sion. The included deltas are noted in the standard outputmessage. sid-list is a comma-
separated list of SIDs. To specify a range of deltas, usea `-' separator instead of a
comma, between two SIDs in the list.-k Suppresses expansion of ID
keywords. -k is implied by the
-e.
-l[p] Retrieves a summary of the
delta table (version log) and write it to a listing file, with the `l.' prefix (called`l.file'). When -lp is used,
write the summary onto the standard output.SunOS 5.11 Last change: 2 Jul 2007 3
User Commands sccs-get(1)
-m Precedes each retrieved line
with the SID of the delta in which it was added to the file. The SID is separated from the line with a TAB.-n Precedes each line with the
%M% ID keyword and a TAB. When
both the -m and -n options are
used, the ID keyword precedes the SID, and the line of text.-p Writes the text of the
retrieved version to the stan-
dard output. All messages that normally go to the standard output are written to the standard error instead.-s Suppresses all output normally
written on the standard out-
put. However, fatal error mes-
sages (which always go to thestandard error) remain unaf-
fected.-t Retrieves the most recently
created (top) delta in a givenrelease (for example: -r1).
/usr/bin/get
-r[sid] Retrieves the version corresponding to the indi-
cated 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 del-
tas, 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 aversion with get. When you omit -r altogether, or
when you omit both release and level, get nor-
mally retrieves the highest release and level.SunOS 5.11 Last change: 2 Jul 2007 4
User Commands sccs-get(1)
If the d flag is set to an SID in the s.file andyou omit the SID, get retrieves the default ver-
sion 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 arelease, level and branch, get retrieves the
highest sequence in that branch./usr/xpg4/bin/get
-r sid | -rsid Same as for /usr/bin/get except
that SID is mandatory.-x sid-list | -xsid-list Excludes the indicated deltas
from the retrieved version. The excluded deltas are noted in thestandard output message. sid-
list is a comma-separated list
of SIDs. To specify a range ofdeltas, use a `-' separator
instead of a comma, between two SIDs in the list.OUTPUT

(1) `R', `L', `B', and `S' are the `release', `level', `branch', and `sequence' components of the SID, respectively; `m' means `maximum'. Thus, for example, `R.mL' means `the maximum level number within release R'; `R.L.(mB+1).1' means `the first sequence number on the new branch (that is, maximum branch number plus one) of level L within release R'. Note: If the SID specified is of the form `R.L', `R.L.B', or `R.L.B.S', each of the specified components must exist.(2) The -b option is effective only if the b flag is
present in the file. An entry of `-' means
`irrelevant'.SunOS 5.11 Last change: 2 Jul 2007 8

(3) This case applies if the d (default SID) flag is not present in the file. If the d flag is present in the file, the SID obtained from the d flag is interpreted as if it had been specified on the command line. Thus, one of the other cases in this table applies. (4) Forces creation of the first delta in a new release. (5) `hR' is the highest existing release that is lower than the specified, nonexistent, release R. (6) Successor.
