Reading a column from excel using shell script in Linux environment

Shell Programming and Scripting

Hi all

I am new to shell scripting. I need to read the 1st column and last of the excel file in linux environment.

Can some one help me with examples

What internal format is the excel file? Comma or tab delimited is probably the only format that is
reasonable to do with shell scripting.

In other words what is the filetype:

.xls .xlsx .csv

?

3

Internal format is comma.
File Type: .csv

May I presume you want to do more than just read those columns? Mayhap reformat or calculate something, or at least output them? Then, a desired output, and,say, a preferred tool to achieve that were helpful to put together a proposal.
