sccs-log(1) Schily´s USER COMMANDS sccs-log(1)

sccs-log, sccslog - create changelog from SCCS history files

sccslog [options] s.file1 .. s.filen

Sccslog creates a Changelog file from SCCS history files.

If a file argument refers to a directory, the directory is scanned for file names that start with ``s.'' and examines all these files.

This program is a SCHILY extension that does not exist in historic sccs implementations.

-a
sccslog normally collects all deltas with the same delta comment and prints them as one log table entry in case the related delta time for the files differs no more than one day. With -a, sccslog collects only those deltas that have been created within 60 seconds.
-aa
With -aa, sccslog collects only deltas that have been created in the same second.
-Cdir
Use dir as base directory for printed file names in the output. This option is used by sccs -R to tell sccslog to print filenames that are suitable for complete project changelog files.
maxdelta=time-spec
Set up a dedicated time delta while collecting deltas with the same delta comment to prints them as one log table entry.

If n is a simple number, the delta is set to the number of seconds.

If n is a number like 3h10m then it is representing a number of seconds that is evaluated as a human readable time spec. The letters that are recognised in the time spec are taken from smhdwy with the following meaning for time units:

s
seconds
m
minutes (60 seconds)
h
hours (60 minutes)
d
days (24 hours)
w
weeks (7 days)
y
years (365 days - a non-leap year)

If neither maxdelta=time-spec nor -a are specified, the default time delta is one day.

-multfile
Allow multiple versions of the same file in a commit. By default, when bundling SCCS deltas with the same delta comment, each file can only appear once. When -multfile has been specified, the same file can appear multiple times if the delta comment is the same.
-p subdir
Tell sccslog to use subdir when dealing with file names.
-R
Inverts the order of the output. This prints older entries first.
usermap=file
Use file instead of the default user map file. This allowd to create dedicated user map files for projects, e.g. to convert the CSRG BSD source code history. See FILES section for the format of the file.
-x
Print all comment lines, even those lines that start with ^Ac_ and thus are no real comment but represent SCCS v6 metadata that has been wrapped as comment to survive modifications by SCCS v4 programs. Such wrapped data is file specific and will prevent to find more files with the same delta comment.
-help
Prints a short summary of the sccslog options and exists.

-Nbulk-spec
Processes a bulk of SCCS history files. This option allows to do an efficient mass processing of SCCS history files.

The bulk-spec parameter is composed from an optional list of flag parameters followed by an optional path specifier.

The following flag types are supported:

none

The following path specifier types are supported:

-N
The file name parameters to the sccslog command are not s.filename files but the names of the g-files. The s.filename names are automatically derived from the g-file names by prepending s. to the last path name component. Both, s.filename and the g-file are in the same directory.
-Ns.
The file name parameters to the sccslog command are s.filename files. The the g-files names are automatically derived by removing s. from the beginning of last path name component of the s.filename. Both, s.filename and the g-file are in the same directory.
-Ndir
The file name parameters to the sccslog command are not s.filename files but the names of the g-files. The s.filename names are put into directory dir, the names are automatically derived from the g-file names by prepending dir/s. to the last path name component.
-Ndir/s.
The file name parameters to the sccslog command are s.filename files in directory dir. The the g-files names are automatically derived by removing dir/s. from the beginning of last path name component of the s.filename.

A typical value for dir is SCCS.

In order to overcome the limited number of exec(2) arguments, it is recommended to use `−' as the file name parameter for sccslog(1) and to send a list of path names to stdin.

-Xextended-options
Specify extended options. The argument extended-options may be a comma separated list of extended option names.

The following extended options are supported, they may be abbreviated as long ad the abbreviation is still unique. Options with parameter may not be abbreviated.

0
When reading filenames from stdin, triggered by a file name argument `-', the filename separator is a null byte instead of a newline. This allows to use long lists with arbitrary filenames.
help
Print a short online help for available options.

The -X option is a SCHILY extension that does not exist in historic sccs implementations.

-V
-version
--version
Prints the sccslog version number string and exists.

To creates a changelog for all SCCS history files in directory SCCS call:
sccslog SCCS/s.*

See environ(5) for descriptions of the following environment variables that affect the execution of val(1): LANG, LC_ALL, LC_CTYPE, LC_MESSAGES, and NLSPATH.

SCCS_NO_HELP
If set, admin(1) 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.

$HOME/.sccs/usermap
This file contains a map list from user names to user descriptions. It consists of a list of lines (each for one user) that start with a user name, followed by white space and a user description. It may e.g. look like: 

joerg   Joerg Schilling <schily@somewhere.com>
ronnie  Ronnie Nowhere <ronnie@nowhere.com>
