sccs-prt(1)

📦 version 2022.10.16, in opensuse-leap 16.0

Okay bestie, welcome to sccs-prt(1) — aka prt — from the User Commands section. This one prints selected parts of an SCCS file, and by default it gives you the delta table (the version log). The output is directly based on text data from the s.files without conversion. It’s giving “archive lore, but make it readable” 💅

🌸 NAME 🌸

sccs-prt, prt — display delta table information from an SCCS file.

✨ SYNOPSIS ✨

/usr/ccs/bin/prt [-abdefistu] [-cdate-time] [-rdate-time]
    [-ysid] [-Xextended-options] [-Nbulk-spec] s.filename...

💖 DESCRIPTION 💖

prt prints selected portions of an SCCS file. By default, it prints the delta table (version log).

The output is directly based on text data from the s.files without conversion.

If a directory name is used in place of the s.filename argument, the prt command applies to all s.files in that directory. Unreadable s.files produce an error; processing continues 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.

🎀 OPTIONS 🎀

If any option other than -y, -c, or -r is supplied, the name of each file being processed (preceded by one NEWLINE and followed by two NEWLINE characters) appears above its contents.

If none of the -u, -f, -t, or -b options are used, -d is assumed. -s, -i are mutually exclusive, as are -c and -r.

  • -a — Display log entries for all deltas, including those marked as removed.
  • -b — Print the body of the s.file.
  • -d — Print delta table entries. This is the default.
  • -e — Everything. This option implies -d, -i, -u, -f, and -t.
  • -f — Print the flags of each named s.file.
  • -i — Print the serial numbers of included, excluded, and ignored deltas.
  • -s — Print only the first line of the delta table entries; that is, only up to the statistics.
  • -t — Print the descriptive text contained in the s.file.
  • -u — Print the user-names and/or numerical group IDs of users allowed to make deltas.
  • -cdate-time — Exclude delta table entries that are specified cutoff date and time. Each entry is printed as a single line, preceded by the name of the SCCS file. This format (also produced by -r, and -y) makes it easy to sort multiple delta tables in chronological order. When both -y and -c, or -y and -r are supplied, prt stops printing when the first of the two conditions is met.
  • -rdate-time — Exclude delta table entries that are newer than the specified cutoff date and time.
  • -ysid — Exclude delta table entries made prior to the SID specified. If no delta in the table has the specified SID, the entire table is printed. If no SID is specified, the most recent delta is printed.
  • -Nbulk-spec — Processes a bulk of SCCS history files. This option allows one 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 prt 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 prt command are s.filename files. 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 prt 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 prt command are s.filename files in directory dir. 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 prt(1) and to send a list of path names to stdin.

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

  • -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 as 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 one 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 prt version number string and exists.

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

🌈 USAGE 🌈

🦋 Output Format 🦋

The following format is used to print those portions of the s.file that are specified by the various options.

  • NEWLINE
  • Type of delta (D or R)
  • SPACE
  • SCCS delta ID (SID)
  • TAB
  • Date and time of creation in the form: yy/mm/dd hh/mm/ss
  • SPACE
  • Username the delta's creator
  • TAB
  • Serial number of the delta
  • SPACE
  • Predecessor delta's serial number
  • TAB
  • Line-by-line change statistics in the form: inserted/deleted/unchanged
  • NEWLINE
  • List of included deltas, followed by a NEWLINE (only if there were any such deltas and the -i option was used)
  • List of excluded deltas, followed by a NEWLINE (only if there were any such deltas and the -i option was used)
  • List of ignored deltas, followed by a NEWLINE (only if there were any such deltas and the -i option was used)
  • List of modification requests (MRs), followed by a NEWLINE (only if any MR numbers were supplied).
  • Lines of the delta commentary (if any), followed by a NEWLINE.

🍓 EXAMPLES 🍓

🌟 Example 1 Examples of prt 🌟

The following command:

example% /usr/ccs/bin/prt -y program.c

produces a one-line display of the delta table entry for the most recent version:

s.program.c:

D 1.6   88/07/06 21:39:39 username 5 4   00159/00080/00636
...

💜 ENVIRONMENT VARIABLES 💜

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

  • SCCS_NO_HELP — If set, prt(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.

⭐ EXIT STATUS ⭐

The following exit values are returned:

  • 0 — Successful completion.
  • 1 — An error occurred.

🎀 FILES 🎀

  • s.file — SCCS history file, see sccsfile(5).
  • dump.core — If the file dump.core exists in the current directory and a fatal signal is received, a coredump is initiated via abort(3).

👑 ATTRIBUTES 👑

See attributes(7) for descriptions of the following attributes:

  • ATTRIBUTE TYPE: Availability
  • ATTRIBUTE VALUE: SUNWsprot

💖 AUTHORS 💖

Okay so history lesson, but make it cute: the SCCS suite was originally written by Marc J. Rochkind at Bell Labs in 1972. Literally a legend.

Release 4.0 of SCCS — which introduced new versions of the programs admin(1), get(1), prt(1), and delta(1) — was published on February 18, 1977. And bestie, this release was a big deal because it introduced the new text based SCCS v4 history file format. Previous SCCS releases used a binary history file format. The way they switched formats and changed the game? Iconic.

The SCCS suite was later maintained by various people at AT&T and Sun Microsystems. Since 2006, the SCCS suite has been maintained by Joerg Schilling and the schilytools project authors. Slay, thank you for your service 🫶.
