Shell Programming and Scripting

All,

Objective : Extract the correct format of a file name.

Please share the script command which will extract the correct format of the file after untarring.
Example : If the file is of .csv format then extract filename.csv
if the file is having .CSV then extract the same.CSV
if the file is .txt then extract .txt
if the file is .TXT then extract .TXT
if the file is .SEQ the extract .SEQ

the tar file can consist of format of the file. ie.txt or .TXT or .csv or .CSV or .SEQ.


Thanks

Please give a much clearer description of what you are trying to do giving sample input, sample output, and a description of what logic is to be used to transform the input(s) you have to the output(s) you want.

Untarring a file extracts all of the files in that archive unless you specify operands telling tar or pax to only process of subset of the archived files. So, after you have untarred a tar archive, why do you need to extract a file from itself???
