(The "gzcat" approach in post #3 and #4 will not work because the "tar" format is also unsuitable for holding in an environment variable).

Hmm. Reading between the lines this looks like an exercise in how to read a the contents of a zipped tar file without unzipping the original file and (strangely) without using "cp".

Find out the names of files in the archive without affecting the original. Then check manually that they do not exist already.
Code:
cat sample.tar.gz | gunzip | tar -tvf -

Extract the files from the archive without affecting the original.
Be very careful that the file names you checked in the previous command do not exist already.
Code:
cat sample.tar.gz | gunzip | tar -xvf -

gzcat can avoid the gunzip pipe:
Code:
ant:/home/vbe $ ll *.gz
-rw-rw-rw-   1 vbe        bin        78273744 Jan 20  2009 AdbeRdr709_hpux_enu.tar.gz
ant:/home/vbe $ gzcat AdbeRdr709_hpux_enu.tar.gz|tar -tvf -

But gzcat is not installed by default on all UNIX and so methyl's option is more likely to work everywhere...

gzcat is a bit redundant anyway. Any gzip I've encountered lets me do this:

Code:
gunzip < filename | ...


...and on my system, gzcat is nothing but a shell script, which runs gunzip.

Hi All,

Thanks for your replies.

Requirement is as follows:

A shell script need to be written, which holds an executable(I am trying to hold that executable in a shell variable). After executing this script in any Linux machine, it need to copy that executable in a predefined path.

Any ideas, how can i implement this script?

Thanks,
Vinay

This makes no sense in English. Are you able to copy the question verbatim without any additional words of your own?
