multiplex is a simple utility in python that pipes a input to a shell command.

multiplex reads all the lines it receives from from the standard inout and applies then the bash shell command, that you specified as parameter.

Provide some list via stdin, and pass the command that you wish to apply for each of that list as a input parameter to the command.

Example:

    cat list_of_ips.txt | multiplex "whois"

If the list passed via stdin has multiple parameters, you can specify their order in the following manner:

    cat list_of_lines_with_multiple_params.txt | multiplex "somecommand --in={0} --out={1}"

Outputs the result of applying the command to each line

# cat domains.txt                        
google.com
apple.com
microsoft.com

# cat domains.txt | python3 multiplex.py "digg +short"
