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.

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.
	      Please notice this option isn't related to the terminal length as in a "80 culums terminal".

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do right to left (RTL) layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter and A4. Default is A4.

       Postscript points
	      Each postscript point equals to 1/72 of an inch. 36 points are 1/2 of an inch.

       --bottom-margin=bm
	      Set bottom margin. Default is 36 postscript points.

       --top-margin=tm
	      Set top margin. Default is 36 postscript points.

       --left-margin=lm
	      Set left margin. Default is 36 postscript points.

       --right-margin=rm
	      Set right margin. Default is 36 postscript points.

       --gutter-width=gw
	      Set gutter width. Default is 40 postscript points.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
