CodeLite IDE

In CodeLite and GDB, how would I debug a process that expects input from stdin as would typically be re-directed from the command line?
In my case I've captured the output from "ls -l" to file.txt, and would like to do something like... ...so the results are reproducible over and over during testing. I can write my own code to read from the file rather than stdin, but if there's a way to read stdin that way I'd prefer it.

Ordinarily it would be: Thank you in advance.

Best regards,

You can't do this with codelite
