Extract root basedir name from a *.tar.gz file

I am working on a script to install a software distribution which ships as a *.tar.gz file. The company doesn't name the dist consistently, but the resulting directory out of the *.tar.gz file (ie: XXX_X_X_X) is consistent and shows the software version.

I'm writing this with BASH-3.25.x (RHEL).

I'm trying to determine how to reliably grab that root directory name for use inside a script.

I have hacked this:
Code:
tar ztvf $DISTFILE | head -1 | sed -e "s/.*F/F/g" | cut -f1 -d"/"

(the dir always starts with F)

This is a crappy hack, but it works. I looked at the manpage for pax and tar and I didn't see anything obvious that accomplishes what I require.

Anyone have a more elegant/reliable way to do this?


Thanks.

NAME
CPAN::DistnameInfo - Extract distribution name and version from a distribution filename SYNOPSIS
my $pathname = "authors/id/G/GB/GBARR/CPAN-DistnameInfo-0.02.tar.gz"; my $d = CPAN::DistnameInfo->new($pathname); my $dist = $d->dist; # "CPAN-DistnameInfo" my $version = $d->version; # "0.02" my $maturity = $d->maturity; # "released" my $filename = $d->filename; # "CPAN-DistnameInfo-0.02.tar.gz" my $cpanid = $d->cpanid; # "GBARR" my $distvname = $d->distvname; # "CPAN-DistnameInfo-0.02" my $extension = $d->extension; # "tar.gz" my $pathname = $d->pathname; # "authors/id/G/GB/GBARR/..." my %prop = $d->properties; DESCRIPTION
Many online services that are centered around CPAN attempt to associate multiple uploads by extracting a distribution name from the filename of the upload. For most distributions this is easy as they have used ExtUtils::MakeMaker or Module::Build to create the distribution, which results in a uniform name. But sadly not all uploads are created in this way. "CPAN::DistnameInfo" uses heuristics that have been learnt by <http://search.cpan.org/> to extract the distribution name and version from filenames and also report if the version is to be treated as a developer release The constructor takes a single pathname, returning an object with the following methods cpanid If the path given looked like a CPAN authors directory path, then this will be the the CPAN id of the author. dist The name of the distribution distvname The file name with any suffix and leading directory names removed filename If the path given looked like a CPAN authors directory path, then this will be the path to the file relative to the detected CPAN author directory. Otherwise it is the path that was passed in. maturity The maturity of the distribution. This will be either "released" or "developer" extension The extension of the distribution, often used to denote the archive type (e.g. 'tar.gz') pathname The pathname that was passed to the constructor when creating the object. properties This will return a list of key-value pairs, suitable for assigning to a hash, for the known properties. version The extracted version AUTHOR
