#!/bin/bash
export FILE_NAME=$1
echo "$FILE_NAME">> cash_out
date >> /xyz/cash_out.out
gpg -e -u "622455DE" -r "44B6A97D" $FILE_NAME >> cash_out


Could you please explain the above script please.

Thanks

It seems pretty straight forward, outputting every line to the file cash_out, including the first argument ($1), the date, and the file (specified as $1) encrypted to the GPG key 44B6A97D and signed with the key 622455DE.

Thanks a lot matir.

I am new to linux. Could please explain me one more time in detail. I would greatly appreciate your help.

Thanks again

Is there any part about which you are confused?

Is this homework? What books on BASH and scripting have you read.
The point is that we need to know where to start....

For example
The first line tells the system to run this script using the program "bash" which is found in /bin.
The second line sets a variable (FILE_NAME) to the value of the first argument passed to the script when it is called.
The third line gets the value of FILE_NAME and redirects it to a file named "cash_out". It is appended to this file.
In the fourth line, there may be an error. It is appending the output of the date command to a different file (cash_out.out) Also the /xyz/ path tells me that this is an example script and not a real one.

Do you know what the script is supposed to do??

One more tip: when learning bash scripting, try the commands one at a time to get a feel for how they work

Thanks a lot Pixallany.

I need to get a file from a Mainframe system and this file needs to be encrypted before we send it to our supplier.

You have educated me everything, except the last line

gpg -e -u "622455DE" -r "44B6A97D" $FILE_NAME >> /xyz/cash_out



could you please walk me thru what exactly is happening in the above statement

Thanks a lot.

But you didn't answer MY questions!!!
Matir already explained the last line:
For the details of the gpg command, do "man gpg"

The script is suppose to get a file from the Mainframe system and then encrypt that file and send it to our supplier, thats the objective of the script.

Thanks again.
