Subject: ShellPkg: make automatically created shells quit automatically
X-Git-Tag: edk2-stable201903~12462
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=ca79c798217775368b6c6a0d0720f221ed2a62ef;p=mirror_edk2.git

ShellPkg: make automatically created shells quit automatically

This creates a new parameter to this shell implementation “_exit” that causes the shell to automatically exit after running the initial specified command line.  This also automatically uses that command in the Execute() API.
