Conundrum - Flexible way to strip extension
Hi,

First post here. I have something that may prove to be difficult.

I have the following files:

Code:
Example1.0.0.tar.gz
Example2.tar
Example3.zip
Example4.0.0.0.0.0.bzip2

I need to remove the file extensions and store as a variable so they look like this:

Code:
Example1.0.0
Example2
Example3
Example4.0.0.0.0.0

The way I see it, there are only two ways of doing it. First, is to check the name for certain terms, say ".tar",".gz",".zip" and then have it removed from the name. If this is the best way, is there an efficient and clean way to do this?

The second way I see, is that I get the name without the extension after I unzip it, then store as a variable. So, with my command: tar xzf $FILE_VAR, is there a way to grab the folder that is spat out?

Code:
$File_VAR = Example1.0.0.tar.gz
tar xzf $FILE_VAR 
<code to find out resulting folder name and store as variable>

Output = Example1.0.0

I would really appreciate any help and advice you can give,

Thanks,

James

Sorry, second post. The whole reason I want to do this is because I need to CD into the untarred directory without knowing what it is actually called.

Thing is because I cant get the name without the extension, I dont know the name of the folder that will be output from the untar operation, then I cant CD into it.

I dont want to specify the folder name that it will be untarred into because I have thousands of these to do.

git-tar-tree

GIT-TAR-TREE(1) 						    Git Manual							   GIT-TAR-TREE(1)

NAME

       git-tar-tree - Create a tar archive of the files in the named tree object

SYNOPSIS

       git tar-tree [--remote=<repo>] <tree-ish> [ <base> ]

DESCRIPTION

       THIS COMMAND IS DEPRECATED. Use git archive with --format=tar option instead (and move the <base> argument to --prefix=base/).

       Creates a tar archive containing the tree structure for the named tree. When <base> is specified it is added as a leading path to the files
       in the generated tar archive.

       git tar-tree behaves differently when given a tree ID versus when given a commit ID or tag ID. In the first case the current time is used
       as modification time of each file in the archive. In the latter case the commit time as recorded in the referenced commit object is used
       instead. Additionally the commit ID is stored in a global extended pax header. It can be extracted using git get-tar-commit-id.

OPTIONS

       <tree-ish>
	   The tree or commit to produce tar archive for. If it is the object name of a commit object.

       <base>
	   Leading path to the files in the resulting tar archive.

       --remote=<repo>
	   Instead of making a tar archive from local repository, retrieve a tar archive from a remote repository.

CONFIGURATION

       tar.umask
	   This variable can be used to restrict the permission bits of tar archive entries. The default is 0002, which turns off the world write
	   bit. The special value "user" indicates that the archiving user's umask will be used instead. See umask(2) for details.

EXAMPLES

       git tar-tree HEAD junk | (cd /var/tmp/ && tar xf -)
	   Create a tar archive that contains the contents of the latest commit on the current branch, and extracts it in /var/tmp/junk directory.

       git tar-tree v1.4.0 git-1.4.0 | gzip >git-1.4.0.tar.gz
	   Create a tarball for v1.4.0 release.

       git tar-tree v1.4.0^{tree} git-1.4.0 | gzip >git-1.4.0.tar.gz
	   Create a tarball for v1.4.0 release, but without a global extended pax header.

       git tar-tree --remote=example.com:git.git v1.4.0 >git-1.4.0.tar
	   Get a tarball v1.4.0 from example.com.

       git tar-tree HEAD:Documentation/ git-docs > git-1.4.0-docs.tar
	   Put everything in the current head's Documentation/ directory into git-1.4.0-docs.tar, with the prefix git-docs/.
