eclean - A cleaning tool for Gentoo distfiles and binary packages.
SYNOPSIS
eclean [global-options] ... <actions> [action-options] ...
eclean-dist [global-options, distfiles-options] ...
eclean-pkg [global-options, packages-options] ...
eclean((-dist,-pkg)) [--help, --version]
DESCRIPTION
eclean is small tool to remove obsolete portage sources files and
binary packages. Used on a regular basis, it prevents your DISTDIR and
PKGDIR directories to infinitely grow, while not deleting files which
may still be useful.
By default, eclean will protect all distfiles or binary packages corre-
sponding to some ebuilds available in the Portage tree. This is the
safest mode, since it will protect whatever may still be useful, for
instance to downgrade a package without downloading its sources for the
second time, or to reinstall a package you unmerge by mistake without
recompiling it. Sure, it's also a mode in which your DISTDIR and
PKGDIR will stay rather big (although still not growing infinitly).
For the 'distfiles', this mode is also quit slow mode because it
requiries some access to the whole Portage tree.
If you use the --destructive option, eclean will only protect files
corresponding to some currently installed package (taking their exact
version into account). It will save much more space, while still pre-
serving sources files around for minor revision bumps, and binaries for
reinstallation of corrupted packages. But it won't keep files for less
usual operations like downgrading or reinstalling an unmerged package.
This is also the fastest execution mode (big difference for distfiles),
and the one used by most other cleaning scripts around like yacleaner
(at least in its version 0.3).
Somewhere in the middle, adding the --package-names option when using
--destructive will protect files corresponding to all existing versions
of installed packages. It will allow easy downgrading without recompi-
lation or redownloading in case of trouble, but won't protect you
against package uninstallation.
In addition to this main modes, some options allow to declare a few
special cases file protection rules:
o --time-limit is useful to protect files which are more recent
than a given amount of time.
o --size-limit (for distfiles only) is useful if you want to pro-
tect files bigger than a given size.
o --fetch-restricted (for distfiles only) is useful to protect
manually downloaded files. But it's also very slow (again, it's
a reading of the whole Portage tree data)...
o Finally, you can list some categories or package names to pro-
tect in exclusion files (see EXCLUSION FILES below).
PARAMETERS
Global options
-C, --nocolor turn off colors on output
-d, --destructive only keep the minimum for a reinstalla-
tion
-e, --exclude-file=<<path>> path to the exclusion file
<<path>> is the absolute path to the exclusion file you want to
use. When this option is not used, default paths are
/etc/eclean/{packages,distfiles}.exclude (if they exist). Use
/dev/null if you have such a file at it standard location and
you want to temporary ignore it.
-i, --interactive ask confirmation before deleting
-n, --package-names protect all versions (--destructive only)
-p, --pretend only display what would be cleaned
-q, --quiet be as quiet as possible, only display errors
-t, --time-limit=<<time>> don't delete files modified since <time>
<<time>> is an amount of time: "1y" is "one year", "2w" is "two
weeks", etc.
Units are: y (years), m (months), w (weeks), d (days) and h
(hours).
-h, --help display the help screen
-V, --version display version informations
Actions
distfiles
Clean files from /usr/portage/distfiles (or whatever else is
your DISTDIR in /etc/make.conf). This action should be useful
to almost any Gentoo user, we all have to big DISTDIRs some-
time...
eclean-dist is a shortcut to call eclean with the "distfiles"
action, for simplified command-line.
packages
Clean files from /usr/portage/packages (or whatever else is your
PKGDIR in /etc/make.conf). This action is in particular useful
for people who use the "buildpkg" or "buildsyspkg" FEATURES
flags.
eclean-pkg is a shortcut to call eclean with the "packages"
action, for simplified command-line.
Options for the ''distfiles'' action
-f, --fetch-restricted protect fetch-restricted files
(--destructive only)
-s, --size-limit=<<size>> don't delete disfiles bigger than <size>
<size> is a size specification: "10M" is "ten megabytes", "200K"
is "two hundreds kilobytes", etc.
Units are: G, M, K and B.
Options for the ''packages'' action
There is no specific option for this action.
EXCLUSION FILES
Exclusions files are lists of packages names or categories you want to
protect in particular. This may be useful to protect more binary pack-
ages for some system related packages for instance. Syntax is the fol-
lowing:
o blank lines and lines starting with a "#" (comments) are
ignored.
o only one entry per line is allowed.
o if a line contains a category name, like "sys-apps", then all
packages from this category will be protected. "sys-apps/*" is
also allowed for aesthetic reasons, but that does NOT mean that
wildcard are supported in any way for any other usage.
o if a line contains a package name ("app-shells/bash"), then this
package will be protected. Versioned atoms like
">=app-shells/bash-3" are NOT supported. Also, the full package
name (with category) is mandatory.
o if a line contains a package name with an exclamation mark in
front ("!sys-apps/portage"), then this package will be excluded
from protection. This is only useful if the category itself was
protected.
o for distfiles protection, a line can also a filename to protect.
This is useful if you have there some files which are not regis-
tered by the ebuilds, like OpenOffice.org i18n files ("helpcon-
tent_33_unix.tgz" for instance).
By default, if it exists, /etc/eclean/packages.exclude (resp. dist-
files.exclude) will be use when action is "packages" (resp. "dist-
files"). This can be overide with the --exclude-file option.
EXAMPLES
Clean distfiles only, with per file confirmation prompt:
## eclean -i distfiles
Check which binary packages could be removed, with a no-color display:
## eclean -Cp packages
Clean binary packages of uninstalled packages, but keep all versions of
installed ones:
## eclean-pkg -d -n
Clean all distfiles except for installed packages (exact version),
those which are less than one month old, bigger than 50MB, or fetch-
restricted:
## eclean-dist -d -t1m -s50M -f
From a crontab, silently clean packages in the safest mode, and then
distfiles in destructive mode but protecting files less than a week
old, every sunday at 1am:
0 1 ** ** sun eclean -C -q packages ;; eclean -C -q -d -t1w distfiles
