ftar - extract tar files using classes
ftar [options] SOURCE
Extract an archive from SOURCE to its target directory using classes.
SOURCE is a directory which contains one or more template files for the
source archive to extract. Depending on the list of defined classes,
one or more archives of the source directory are selected and extracted
to the target. The base target directory is the name of the source
directory. Template file must have suffix .tar, .tar.gz, or
The exit code returned by ftar is mostly 0. For every successfully
extracted tar file, a log message is printed to standard output.
Options -c, -s, -t (or their analog variables) and a SOURCE are
-1 Use only one archive file matching a class name.
Define classes. Multiple classes must be space separated. The
first class has the lowest priority. If not specified, use the
classes from the file /tmp/FAI_CLASES.
-d Delete all files in target directory before extracting the
-D Create debugging output.
-h Show help, version and summary of options.
-r Recursively remove files in target directory before extracting

Suppose the source directory /files/etc/alternatives consists of the
Each file is a compressed archive. If only class DATALESS is defined,
the following command
# ftar -s /files -t /tmp/target /etc/alternatives
is equal to
# tar -C /tmp/target -zxf /files/etc/alternatives/DATALESS.tar.gz
If additionally class ant01 is defined, the following command is also
# tar -C /tmp/target -jxf /files/etc/alternatives/ant01.tar.bz2
If only one archive should be extracted, the class with highest
priority is used.
Do not create a file DEFAULT if no reasonable default configuration
file can be used. It’s better to exit with an error than to extract a
This command can also be used to maintain your complete directory trees
on a huge number of hosts.
