.Dt PKG_VERSION 1
|
|
.Os FreeBSD
|
|
.Sh NAME
|
|
.Nm pkg_version
|
|
.Nd summarize installed versions of packages
|
|
.Sh SYNOPSIS
|
|
.Nm pkg_version
|
|
.Op Fl cdhv
|
|
.Op Fl l Ar limchar
|
|
.Op Ar index
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
command is used to produce a report of non-base software packages
|
|
installed using the
|
|
.Xr pkg_add 1
|
|
command. Version numbers are compared against an
|
|
index file, to see which packages might need updating.
|
|
.Pp
|
|
Each package name is printed, along with a one-character status flag:
|
|
.Bl -tag -width indent
|
|
.It Li =
|
|
The installed version of the package matches the index.
|
|
.It Li <
|
|
The installed version of the package is older than the version listed
|
|
in the index.
|
|
.It Li >
|
|
The installed version of the package is newer than listed in the
|
|
index.
|
|
.It Li ?
|
|
The relationship between the installed version of a package and the
|
|
index file could not be determined. A common reason for this message
|
|
is that there are multiple versions of a particular software package
|
|
installed, or that multiple versions are listed in the index file.
|
|
Examples from the
|
|
.Fx
|
|
ports collection are the Tcl toolkit or the
|
|
.Tn EMACS
|
|
editor.
|
|
.Sh OPTIONS
|
|
.Nm
|
|
supports several command-line arguments:
|
|
.Bl -tag -width indent
|
|
.It Fl c
|
|
Enable commands output. Commands output includes the commands you should
|
|
type to update your installed packages to the latest versions in the ports
|
|
system.
|
|
.It Fl d
|
|
Enable debugging output.
|
|
.It Fl h
|
|
Print help message.
|
|
.It Fl l
|
|
Limit the output to those packages whose status flag matches
|
|
.Ar limchar .
|
|
You may specify more than one character to match in
|
|
.Ar limchar .
|
|
Note that because some of the status flag characters are also special
|
|
to the shell, it is best to quote
|
|
.Ar limchar
|
|
with single quotes.
|
|
.It Fl v
|
|
Enable verbose output. Verbose output includes some English-text
|
|
interpretations of the version number comparisons, as well as the
|
|
version numbers compared for each package. Non-verbose output is
|
|
probably easier for programs or scripts to parse.
|
|
.It Ar index
|
|
Specify the index to be used as a basis of comparison. This index can
|
|
be specified as a filename (in the local filesystem) or a URL. Any
|
|
URL understandable by
|
|
.Xr fetch 1
|
|
can be used here. If no
|
|
.Ar index
|
|
file is specified on the command line,
|
|
.Pa /usr/ports/INDEX
|
|
is used.

|
.Sh EXAMPLES
|
|
The following is a typical invocation of the
|
|
.Nm
|
|
command, which checks the installed packages against the local ports
|
|
index file:
|
|
.Pp
|
|
.Dl % pkg_version -v
|
|
.Pp
|
|
The command below generates a report against
|
|
the version numbers in the on-line ports collection:
|
|
.Pp
|
|
.Dl % pkg_version ftp://ftp.FreeBSD.org/pub/FreeBSD/branches/-current/ports/INDEX
|
|
.Pp
|
|
The command below generates a file of commands to run to update the installed
|
|
files.
|
|
It is
|
|
.Bf Em
|
|
not
|
|
.Ef
|
|
suggested that you run these commands automatically.
|
|
Always review the
|
|
suggestions, and then cut-and-paste (or retype) the commands you want to run.

.Sh BUGS
|
|
There should be a better way of dealing with packages that
|
|
can have more than one installed version.
|
|
.Pp
|
|
Patch levels aren't handled
|
|
very well (i.e. version numbers of the form 1.2p3 or 1.2pl3).
|
|
.Pp
|
|
Updates to packages
|
|
that don't change the version number (e.g. small delta bugfixes in the
|
|
package/port itself) aren't detected.
|
|
.Pp
|
|
Commands output doesn't know about dependencies between packages.
|
|
For
|
|
example, you might have two versions of Tcl installed because two other
|
|
packages require the different versions.
|
|
.Nm
|
|
will suggest removing the out-of-date version.
|
|
.Pp
|
|
Commands output assumes you install new software using the ports system,
|
|
rather than using
|
|
.Xr pkg_add 1 .
