code

This is less than 100 lines of code, including the rules.

interactive

User input can match the regex of a rule, and the statements for Windows or Linux are executed.

rules

It is a yaml structure. It has a list of rules (names) that are just a handle. Per rule it defines match, desc, Windows_NT and Linux. User input is compared per rule if it matches the match. If so it executes the Windows_NT or Linux statements. And desc is just a description. A match can include parameters, like an IP address.

example rules

When the user input is pwd, then on Windows, the cd and on Linux, the pwd is executed.

pwd:
    match: ^pwd$
    desc: Print Working Directory
    Windows_NT: cd
    Linux: pwd

When the user input is info then it executes multiple statements, and these don't need to be the same.

info:
    match: ^info$
    desc: Info on the system
    Windows_NT: |
        cd
        whoami
        dir .
    Linux: |
        pwd
        whoami
        id
        ls -al

This id rule includes a comment.

id:
    match: ^id$
    desc: Id of user
    Windows_NT: whoami  # for windows
    Linux: id

ls:
    match: ^ls$
    desc: Dir
    Windows_NT: dir
    Linux: ls -al

Here a ping to localhost shows a difference in an script argument on two operating systems.

ping:
    match: ^ping$
    desc: Ping
    Windows_NT: ping -n 1 127.0.0.1
    Linux: ping -c 1 127.0.0.1

This rule has a regex that can take a parameter that is then used in the scripts. In this case after a ping it accepts a pattern like 127.0.0.1 and names it ip, using ?P<ip> as named capturing group. That parameter is then used in the script as {ip}.

pingip:
    match: ^ping (?P<ip>[.0-9]*)$
    desc: Ping address
    Windows_NT: ping -n 1 {ip}
    Linux: ping -c 1 {ip}
