Hi,

  you can pass commands to the ROOT prompt directly from your shell (or a shell script) by doing, following your example:

$ root -l <<EOC

.x myCScript.C
.x mySecondCScript.C
.q

EOC You can of course use environment variables between "<<EOC" and "EOC" (and you can use the string you want instead of "EOC").

Cheers,
