Script to access multiple file and operate on single file
We have three files as mentioned below:
1. main_file.txt: This is the file in which all operations will be done. Which means this file will be signed by using the below two files
2. signature_file.txt: This is a status file and contains two signatures.
3. command.txt:file contains two commands which needs to be performed on main_file.txt as mentioned above.
main_file.txt looks like below:
Code:
 
 11,London,UK,Eurpoe,23
 13,Manchester,UK,Europe,21
 16,Florence, Italy, Europe, 212

signature_file.txt looks like below:

Code:
 
 C&8339334343221212134343434343223131324222242322
 D%343434343u3i4348t2233n2k4n24342131l#424342-323232



Command.txt file looks like below:

Code:
 
 Java <something something1>  main_file.txt
 Java <something something2>  main_file.txt



Now the script should do the following operation.

1. Insert a new line in the end of the main_file.txt
2. Pick the first signature (line 1) of the signature file and put it in the end of the main_file.txt
3. Insert a new line in the end of the main_file.txt
4. Pick the first command from the command.txt file and run it.
5. This command will generate a text output. Put that text output in the end of the main_file.txt.
6. Insert a new line in the end of the main_file.txt
7. Pick the second signature (line1) of the signature file and put it in the end of the main_file.txt
8. Insert a new line in the end of the main_file.txt
9. Pick the second command from the command.txt file and run it.
10. This command will generate a text output. Put that text output in the end of the main_file.txt. (No new line insertion after this point).

Can anybody help me in getting this sorted? I am at the loss as how to achieve this?

Thanks a ton.

That sounds quite intangible. How would those text outputs look like, and how the final result. Does

1. Insert a new line in the end of the main_file.txt
2. Pick the first signature (line 1) of the signature file and put it in the end of the main_file.txt

create an empty line before the signature?

Hi Rudi,

Basically it only means that insert a first line of signature in the main_file.txt file. Actually I was thinking it loud to make it simple for myself.
