I have two files with me file1.txt and file2.txt
ccc is related to 333 only, bbb is related to 222 only and aaa is related to 111 only.
I have to get the values from each of the file and pass them in the URL like:
I wrote a nested for reading each of them line by line but obviously, the inner loop for file2 runs 3 times for processing first record of the first loop.
Please become accustomed to provide decent context info of your problem.
It is always helpful to support a request with system info like OS and shell, related environment (variables, options), preferred tools, adequate (representative) sample input and desired output data and the logics connecting the two, and, if existent, system (error) messages verbatim, to avoid ambiguities and keep people from guessing.
Should your desire be to solve above in shell, and yours is bourne compatible, there are many threads dealing with and presenting solutions to your problem. A very simplified approach would be to use redirection from extra file descriptors:
Have you tried the paste command?
The output will be from the same line number from each file separated with a tab unless you choose some other character. The output can be piped or redirected like other unix commands.
