NAME
alien - Convert or install an alien binary package
SYNOPSIS
alien [--to-deb] [--to-rpm] [--to-tgz] [--to-slp] [options] file [...]
DESCRIPTION
alien is a program that converts between Red Hat rpm, Debian deb,
Stampede slp, Slackware tgz, and Solaris pkg file formats. If you want
to use a package from another linux distribution than the one you have
installed on your system, you can use alien to convert it to your
preferred package format and install it. It also supports LSB packages.
WARNING
alien should not be used to replace important system packages, like
init, libc, or other things that are essential for the functioning of
your system. Many of these packages are set up differently by the
different distributions, and packages from the different distributions
cannot be used interchangeably. In general, if you can't remove a
package without breaking your system, don't try to replace it with an
alien version.
PACKAGE FORMAT NOTES
rpm For converting to and from rpm format the Red Hat Package Manager
must be installed.
lsb Unlike the other package formats, alien can handle the dependencies
of lsb packages if the destination package format supports
dependencies. Note that this means that the package generated from
a lsb package will depend on a package named "lsb" -- your
distribution should provide a package by that name, if it is lsb
compliant. The scripts in the lsb package will be converted by
default as well.
To generate lsb packages, the Red Hat Package Manager must be
installed, and alien will use by preference a program named lsb-
rpm, if it exists. No guarantees are made that the generated lsb
packages will be fully LSB compliant, and it's rather unlikely they
will unless you build them in the lsbdev environment.
Note that unlike other package formats, converting an LSB package
to another format will not cause its minor version number to be
changed.
deb For converting to (but not from) deb format, the gcc, make,
debhelper, dpkg-dev, and dpkg packages must be installed.
tgz Note that when converting from the tgz format, alien will simply
generate an output package that has the same files in it as are in
the tgz file. This only works well if the tgz file has precompiled
binaries in it in a standard linux directory tree. Do NOT run alien
on tar files with source code in them, unless you want this source
code to be installed in your root directory when you install the
package!
When using alien to convert a tgz package, all files in /etc in are
assumed to be configuration files.
pkg To manipulate packages in the Solaris pkg format (which is really
the SV datastream package format), you will need the Solaris
pkginfo and pkgtrans tools.
OPTIONS
alien will convert all the files you pass into it into all the output
types you specify. If no output type is specified, it defaults to
converting to deb format.
file [...]
The list of package files to convert.
-d, --to-deb
Make debian packages. This is the default.
-r, --to-rpm
Make rpm packages.
-t, --to-tgz
Make tgz packages.
--to-slp
Make slp packages.
-p, --to-pkg
Make Solaris pkg packages.
-i, --install
Automatically install each generated package, and remove the
package file after it has been installed.
-g, --generate
Generate a temporary directory suitable for building a package
from, but do not actually create the package. This is useful if you
want to move files around in the package before building it. The
package can be built from this temporary directory by running
"debian/rules binary", if you were creating a Debian package, or by
running "rpmbuild -bb <packagename>.spec" if you were creating a
Red Hat package.
-s, --single
Like -g, but do not generate the packagename.orig directory. This
is only useful when you are very low on disk space and are
generating a debian package.
-c, --scripts
Try to convert the scripts that are meant to be run when the
package is installed and removed. Use this with caution, because
these scripts might be designed to work on a system unlike your
own, and could cause problems. It is recommended that you examine
the scripts by hand and check to see what they do before using this
option.
This is enabled by default when converting from lsb packages.
--patch=patch
Specify the patch to be used instead of automatically looking the
patch up in /var/lib/alien. This has no effect unless a debian
package is being built.
--anypatch
Be less strict about which patch file is used, perhaps attempting
to use a patch file for an older version of the package. This is
not guaranteed to always work; older patches may not necessarily
work with newer packages.
--nopatch
Do not use any patch files.
--description=desc
Specify a description for the package. This only has an effect when
converting from the tgz package format, which lacks descriptions.
--version=version
Specify a version for the package. This only has an effect when
converting from the tgz package format, which may lack version
information.
Note that without an argument, this displays the version of alien
instead.
-T, --test
Test the generated packages. Currently this is only supported for
debian packages, which, if lintian is installed, will be tested
with lintian and lintian's output displayed.
-k, --keep-version
By default, alien adds one to the minor version number of each
package it converts. If this option is given, alien will not do
this.
--bump=number
Instead of incrementing the version number of the converted package
by 1, increment it by the given number.
--fixperms
Sanitize all file owners and permissions when building a deb. This
may be useful if the original package is a mess. On the other hand,
it may break some things to mess with their permissions and owners
to the degree this does, so it defaults to off. This can only be
used when converting to debian packages.
--target=architecture
Force the architecture of the generated package to the given
string.
-v, --verbose
Be verbose: Display each command alien runs in the process of
converting a package.
--veryverbose
Be verbose as with --verbose, but also display the output of each
command run. Some commands may generate a lot of output.
-h, --help
Display a short usage summary.
-V, --version
Display the version of alien.
EXAMPLES
Here are some examples of the use of alien:
alien --to-deb package.rpm
Convert the package.rpm into a package.deb
alien --to-rpm package.deb
Convert the package.deb into a package.rpm
alien -i package.rpm
Convert the package.rpm into a package.deb (converting to a .deb
package is default, so you need not specify --to-deb), and install
the generated package.
alien --to-deb --to-rpm --to-tgz --to-slp foo.deb bar.rpm baz.tgz
Creates 9 new packages. When it is done, foo bar and baz are
available in all 4 package formats.
ENVIRONMENT
alien recognizes the following environment variables:
RPMBUILDOPT
Options to pass to rpm when it is building a package.
RPMINSTALLOPT
Options to pass to rpm when it is installing a package.
EMAIL
If set, alien assumes this is your email address. Email addresses
are included in generated debian packages.
