Capture the output with a script

[zombie_]

Hello every one,

I got a program that i run and get an output from it -> ./prog -i file-name

However I want to write a script to capture its output and write it in the output-file.txt.

How I can write the script (the-script) such that the 'file-name' treated a a variable?

Thanks in advance,

[Iowan]
