cmd chaining in -cmd flag or run scripts

[kynrai]

Im looking for a way to chain commands with the templ generate proxy watch. Im considering altering https://github.com/a-h/templ/blob/main/cmd/templ/generatecmd/run/run_unix.go#L55 if it makes sense to do so, or maybe allow multiple commands to be specified,

Im ultimately just looking for a clean way to have templ run al the tools i need instead of relying on extra tools

Lets say I have a script in scripts/build.sh which runs something like tailwind and a bundler

something like the following as a makefile command should in theory work

templ generate -watch -proxy="http://localhost:8080" \
		-watch-pattern="(.+\\.go$$)|(.+\\.templ$$)|(.+_templ\\.txt$$)|(.+\\.css$$)|(.+\\.ts$$)" \
		-cmd="scripts/build.sh" -v

I will always get Error executing command [ error=fork/exec scripts/build.sh: no such file or directory ]

I could also try something like

templ generate -watch -proxy="http://localhost:8080" \
		-watch-pattern="(.+\\.go$$)|(.+\\.templ$$)|(.+_templ\\.txt$$)|(.+\\.css$$)|(.+\\.ts$$)" \
		-cmd="cmd1 && cmd2" -v

Or

templ generate -watch -proxy="http://localhost:8080" \
		-watch-pattern="(.+\\.go$$)|(.+\\.templ$$)|(.+_templ\\.txt$$)|(.+\\.css$$)|(.+\\.ts$$)" \
		-cmd="cmd1; cmd2;" -v

But i think this fails due to the way go executes commands,

possibly similar to this issue

even trying simple commands in the -cmd input causes odd outputs, like pwd; pwd; or pwd && pwd

side note, my original code, the commands are run in a Makefile hence the regex has $$ escapes
