I have downloaded the following file on my Linux computer:
wget https://github.com/tomwhite/hadoop-book/blob/master/input/ncdc/all/1901.gz
I tried to unzip the file using gunzip 1901.gz but it did not work. I check the file format using 'file' command and it says:
1901.gz: HTML document, UTF-8 Unicode text, with very long lines
I am quite new to Linux. May I know how can I successfully extract the data for usage?
You have downloaded a regular HTML file and you called it something.gz, hoping that that would turn it into a zipped file, but this is not how it works: your file is not a zipped file, so there's no reason trying to unzip it.

When I try to cat in one file, for exemple cert.pem I receive ab error: No such file or directory
These are symbolic links - special files that just contain the path to another file. When you cat them, they essentially redirect to the file they link to. However, as evident by the red color in the ls output, these links are broken - they point to files that do not exist, and thus you get that error when you try to cat them.

Using gedit, I want to create a config.env file, how do I change the extension as simply naming it config.env doesn't work.
THanks in advance
It really doesn't matter what the file extension is, as long as it is in a linux machine.
Just execute file <filename> to know the file type.
However you could try this:
Save the file as it is like config.txt or other and execute the below command
mv config.txt config.env

I there any unix command which will convert xls file into xlsx file?
Also i have tried using mv command, it is changing the extension as well. But then i am not able to open the xlsx file.
mv .xls .xlsx
Any suggestion will be really appreciate.
As far as I know, this is not something you can easily do with standard unix tools.
You can use LibreOffice:
libreoffice --convert-to xlsx my.xls --headless
Or maybe find an online converter and submit your file to it.

I have a script witch use lpr to print the output to a PDF file.
I would like to change the location or even the file name of the saved file.
I read several forums about lpr and did not find anything on how to specify the name and the directory of the printed pdf.
Instead I always get a standard name in my PDF directory.
Thank you!
Take a look at cups-pdf, https://help.ubuntu.com/community/PDFPrinting . You can configure the output directory and filename with it. The configuration file is /etc/cups/cups-pdf.conf.
