Rewriting of the original watch linux command in order to add some new feature to it:

• Better view.
• Execute 2, 3 or 4 commands simultaneously.

I'm working on Kubernetes every single day. And my team and I are using a lot the watch tool to monitor if our last change was well applied by Flux for example. I usually need to open 2, 3 in my term/tmux to be able to monitor everything. With this tool, we will be able to monitor 2 or 3 things at once.

# basic execution
gwatch "command"

# interval selection (in seconds)
gwatch "command" -i 5

# multiple commands
gwatch "command1" "command2" "command3" "command4"
or
gwatch -c "command1" -c "command2" -c ...

Clone the repository then:

$ make build

• Multicommand support.
• Change interval support.
• Exec commands asynchronously.
• Highlight differences with -d or --differences flag
• Choose the layout when there is 2 or 3 commandes ?
• Handle command with a pipe -> "kubectl get pods | grep test"
