vl prints various information about an AtFS object repository. While
its main operation is to list the contents of an object repository in a
manner similar to ls(1), vl knows about many options that extract
additional information about individual versions or version histories.
If vl is invoked without any name arguments, it simply prints the
contents of the object repository, including files (busy versions) and
directories in the current directory. Version objects in the object
repository are represented as filenames with a bracketed version
identification extension. Generally, vl tries to give the illusion, as
were all the versions in the object repository regular files in the
current directory. While busy versions - which are regular files - may
be manipulated by all commands and tools that operate on files, version
objects can only be manipulated by special tools (ShapeTools) that
operate on the object repository. The tools that operate on the object
repository, however, can also access regular files because these are
also part of the object repository.
With the -h option given, vl prints out one information item per
history rather than per version. Default output in this case is a list
of history and directory names with the range(s) of available versions
following in brackets.
If filenames are given as arguments to vl, similarly to ls(1) only
information about these object histories will be printed. Object names
may also be given in bound version notation, i.e. a notation that
identifies a particular version of an object (e.g. mkattr.c[2.4]). It
is also possible to use a previously assigned symbolic name rather than
a numerical version identification (e.g. mkattr.c[tools-V4R3]). Make
sure to escape the bracket symbols as these usually have meaning to the
shell. For further version binding possibilities (the version binding
options) see the vbind(1) manual page.
The program vlog prints the log-entry for specified objects. Log-
entries usually describe the reason for a particular change to the
design object that led to the creation of the specified revision(s).
All options also available in the ls(1) programs are marked on the
Print short information about usage of this command.
Force single column output.
List all entries, even those with a name beginning with a '.'
and the 'AtFS' entry. This option is default when vl is called
by the super user.
-all List all available information.
Print only information about objects that have the specified
attribute with the given values. The attribute value match is
done without attribute expansion, even if -expand is set.
attribute may also be a standard attribute. For a complete list
of standard attributes names see the vadm(1) manual page.
Same as -a, but '.', '..', and 'AtFS' are not listed.
Sort the list of printed entries by the time of last status
-cache List entries from the derived object cache too.
Force multi column output. This is default when printing just
the entry names (no -l and no -p option) and output goes to a
With a directory name given as argument, list the directory
itself rather than its contents.
Expand attribute values before printing. Attribute values may
contain citations of other attributes, or they may start with a
special character ('^', '!' or '*') indicating that they need
some kind of processing to determine the real attribute value
(see vattr(1) for details). With the -expand option given, all
citations will be evaluated and the attribute will be evaluated
-fast Fast operation. Suppresses reader/writer synchronisation on
AtFS archive files and ignores non-standard attributes. In
combination with -h (histories), a short output is generated,
that lists only the names of all histories and not their
-format format string
Specify custom-format for information printed about objects.
This is a simple report generation facility for the shapeTools
toolkit. The format string can be any string, but typically
contains attribute citations (see retrv). As shapeTools
attribute citations use a syntax that contains dollar-
characters, it is advisable, to specify format strings in
single-quotes to prevent shell from trying to apply variable
Format strings can contain simple layout specifications (`
for newline characters, and ` ' for tabs. `\' is a single
The format of the output of vl -l could for example be
specified as follows:
vl -format ´$__mode$ $__state$$__author$ \
$__size$ $__mtime$ $__self$
While the example only illustrates use of standard attributes,
it is in fact possible to use any object attribute (i.e. user-
defined attributes) in the format specification.
Append a symbolic file type character to each name. Directories
are marked with a `/', sockets with a `=', symbolic links with
a `@', executable files with `*', and derived objects with a
`$'. If the file is locked a `^' is additionally appended.
Print the group of the entry owner (...) .
-h Print histories instead of versions. All versions with the same
name are folded together to one printed entry. All version
binding options (see vbind(1)) are ignored, when displaying
Print message of intention for change. An intention message can
be set while retrieving a version using retrv with option
List in long format, giving mode, version state, author, size
in bytes, the save date, and version identification. For busy
versions the date field will contain the time of last
modification rather than the save date. The status of a version
is printed as: b for busy, s for saved, p for proposed, P for
published, a for accessed, f for frozen, and $ for derived.
-lll Same as -l -locked -locker.
Print only locked versions.
Print the locker instead of the author and last locking date
instead of last modification or save date.
-log Print the log entry for each version.
Follow symbolic links. If a given name is a symbolic link, list
the object referenced by the link rather than the link itself.
Do not expand attribute values. This is the default, except
when the -format option is set. Check -expand or vattr(1) for
more information on attribute expansion.
-O Print the version owner instead of the author.
-p "all" | attribute name
Print the value of the given attribute. With the string 'all'
given as argument to the -p option, print all non standard
Replace all non graphic character by '?' before printing. This
is the default when output goes to a terminal.
-Q Quiet Flag. Suppress any output to standard output. Only error
messages will be printed to standard error.
Reverse the order of the entries printed.
Operate recursively visiting all subdirectories encountered.
-S Print version states verbosely.
Sort the list of printed entries by the modification time.
Sort the list of printed entries by time of last access.
-U Show user identifications as user@domain rather than just the
-v Print versions. This is the default (counterpart to
Print only the version identification of this program.
Do multi-column output with the entries sorted across rather
than down the page.
When using the version binding options -since and -before, the vl
output may look confusing. -since and -before define a time interval
for save dates but vl displays the date of last modification, which may
be older than the save date.
'.' and '..' are always ignored when displaying versions.
Several Options are not available when displaying histories (-h
option). These are: -all, -attr, -c, -format, -intent, -locked, -log,
-n, -p, -R, -t, and -u.
The displayed group name (-g option) may be wrong for busy versions.
-noexpand does not work together with -format.
-q, and -F are not implemented.
