Very basic implementation of the watch utility from Linux, but for Windows. Nothing too fancy, but it gets the job done. If this is your first time hearing about watch, it's essentially a utility that repeats a given command at a set interval and refreshes the screen as it does so.
--help (-h) | Prints This Help Page
|
--interval (-i) | Sets the command repetition interval in milliseconds. Defaults to 1000ms.
|
--verbose (-v) | Toggles the printing of additional information related to the command's execution.
| Currently only displays the return code after every execution.
|
--command (-c) | The most important argument. Everything after this will be treated as the command that
| should be watched. This should be placed at the very end of all other arguments.
| In some some cases (e.g. pipes) encapsulating the command in quotes may be necessary.
I must stress that --command (-c) should be the very last argument, as everything after it will be treated as a command, allowing for syntax such as this: watch -c ipconfig /all
where ipconfig and /all are two separate argv arguments but get treated as one as they are concatenated to form a single string ipconfig /all without the need of quotes.
In some cases, encapsulating the command you want to watch with quotes is going to be necessary, such as when using > or | as part of the command, since cmd.exe won't treat it as plain text otherwise.
watch -i 5000 -c "tasklist | find \"firefox\" /i"
