It expects to be installed in their places -- # in other words, `basename "$0"` might be poweron-vm-default. # # Handy reference/shorthand used in this doc/scripts: # TOOLS_CONFDIR ::= Depends on platform and installation settings. Likely # "/etc/vmware-tools" or # "/Library/Application Support/VMware Tools" # powerOp ::= One of "poweron-vm", "poweroff-vm", "suspend-vm", and # "resume-vm". # vmwScriptDir ::= $TOOLS_CONFDIR/scripts/vmware # userScriptDir ::= $TOOLS_CONFDIR/scripts/${powerOp}-default.d # # End users may install scripts of their own under $userScriptDir. They # are executed in alphabetical order with "$powerOp" as the only argument. # # NB: This directory layout remains to preserve backwards compatibility. End # users are free to write a single script which uses its only parameter # (${powerOp}) as a discriminator, and then install symlinks to it in each # of the ${powerOp}-default.d directories. # # On power-on and resume, VMware's scripts execute before the end user's. On # suspend and power-off, the end user's execute before VMware's. (This way, # VMware stops services only after the user's scripts have finished their # work, and conversely restores the same services before the user's scripts # attempt to use them.) # # Should any script exit non-zero, only its value will be saved to exitCode. # (Any further non-zero exits will have no effect on exitCode.) This script # exits with $exitCode. # # XXX Consider using the available/enabled pattern for VMware's scripts. # # XXX This should be staged as a single executable whereby the desired # power operation is passed in as a parameter. (I.e., one would run # "/path/to/statechange.sh suspend-vm" rather than having to install # statechange.sh as suspend-vm-default.) # echo `date` ": Executing '$0'" # See above.
