.TH PKG_CUTLEAVES 1 "Jul 2003" FreeBSD
|
||||
.SH NAME
|
||||
pkg_cutleaves \- deinstall 'leaf' packages
|
||||
.SH SYNOPSIS
|
||||
.B pkg_cutleaves [-c] [-F] [-l] [-R] [-x]
|
||||
.SH DESCRIPTION
|
||||
.B pkg_cutleaves
|
||||
finds installed 'leaf' packages, i.e. packages that are not referenced
|
||||
by any other installed package, and lets you decide for each one if you
|
||||
want to keep or deinstall it (via pkg_deinstall(1)).
|
||||
Once the packages marked for removal have been flushed/deinstalled,
|
||||
you'll be asked if you want to do another run (to see packages that have
|
||||
become 'leaves' now because you've deinstalled the package(s) that
|
||||
depended on them). In every run you will be shown only packages that you
|
||||
haven't marked for keeping, yet.
|
||||
|
||||
Note that your package registry database should be up to date for this
|
||||
to work properly, so it might be a good idea to run pkgdb(1) before
|
||||
running pkg_cutleaves.
|
||||
.SH OPTIONS
|
||||
.IP -c
|
||||
When listing leaf packages, also print their comments/short
|
||||
descriptions. Will be ignored unless the '-l' parameter is given, too.
|
||||
.IP -F
|
||||
Run 'pkgdb -F' after each deinstallation run, to make sure the package
|
||||
registry database is up to date. (Note: This is mostly for convenience;
|
||||
it shouldn't be necessary to run 'pkgdb -F' after each run, but it
|
||||
doesn't hurt, either.)
|
||||
.IP -l
|
||||
List leaf packages only, one per line, and don't ask for anything to be
|
||||
deinstalled.
|
||||
.IP -R
|
||||
Run 'pkg_deinstall -R' instead of plain 'pkg_deinstall', so packages the
|
||||
removed leaf packages depend(ed) on will be deinstalled, too.
|
||||
.IP -x
|
||||
Exclude packages matching expressions given in the exclude file.
|
||||
.SH FILES
|
||||
.I /usr/local/etc/pkg_leaves.exclude
|
||||
.RS
|
||||
An optional list for excluding packages when the '-x' option is given.
|
||||
If the beginning of a package's name matches any line (except comment or
|
||||
empty lines) in this file, the package will not be listed/offered for
|
||||
removal (e.g., a line saying just 'XFree86' (without the 's) will
|
||||
exclude all packages with names starting with 'XFree86').

.TH PKG_CUTLEAVES 1 "Jul 2003" FreeBSD
|
||||
.SH NAME
|
||||
pkg_cutleaves \- deinstall 'leaf' packages
|
||||
.SH SYNOPSIS
|
||||
.B pkg_cutleaves [-c] [-F] [-l] [-R] [-x]
|
||||
.SH DESCRIPTION
|
||||
.B pkg_cutleaves
|
||||
finds installed 'leaf' packages, i.e. packages that are not referenced
|
||||
by any other installed package, and lets you decide for each one if you
|
||||
want to keep or deinstall it (via pkg_deinstall(1)).
|
||||
Once the packages marked for removal have been flushed/deinstalled,
|
||||
you'll be asked if you want to do another run (to see packages that have
|
||||
become 'leaves' now because you've deinstalled the package(s) that
|
||||
depended on them). In every run you will be shown only packages that you
|
||||
haven't marked for keeping, yet.
|
||||
|
||||
Note that your package registry database should be up to date for this
|
||||
to work properly, so it might be a good idea to run pkgdb(1) before
|
||||
running pkg_cutleaves.
|
||||
.SH OPTIONS
|
||||
.IP -c
|
||||
When listing leaf packages, also print their comments/short
|
||||
descriptions. Will be ignored unless the '-l' parameter is given, too.
|
||||
.IP -F
|
||||
Run 'pkgdb -F' after each deinstallation run, to make sure the package
|
||||
registry database is up to date. (Note: This is mostly for convenience;
|
||||
it shouldn't be necessary to run 'pkgdb -F' after each run, but it
|
||||
doesn't hurt, either.)
|
||||
.IP -l
|
||||
List leaf packages only, one per line, and don't ask for anything to be
|
||||
deinstalled.
|
||||
.IP -R
|
||||
Run 'pkg_deinstall -R' instead of plain 'pkg_deinstall', so packages the
|
||||
removed leaf packages depend(ed) on will be deinstalled, too.
|
||||
.IP -x
|
||||
Exclude packages matching expressions given in the exclude file.
|
||||
.SH FILES
|
||||
.I /usr/local/etc/pkg_leaves.exclude
|
||||
.RS
|
||||
An optional list for excluding packages when the '-x' option is given.
|
||||
If the beginning of a package's name matches any line (except comment or
|
||||
empty lines) in this file, the package will not be listed/offered for
|
||||
removal (e.g., a line saying just 'XFree86' (without the 's) will
|
||||
exclude all packages with names starting with 'XFree86').
