Shows a list of running virtual machines on a vmware host (workstation/server/esx/etc.)
Again, this command is vmware-specific.
There are also other things you can do with `vmrun`. Just simply type vmrun by itself (no arguments) to get a readout of other things you can do with it.
There is no output from this command. The command boots a virtual machine and you will have to wait for the boot sequence to complete before you can ping or connect to the virtual machine via ssh/rdp/vnc/nx/etc.
To check if the table-of-content in a LaTeX document is up-to-date, copy it to a backup before running LaTeX and compare the new .toc to the backup. If they are identical, it is updated. If not, you need to run LaTeX again.

This command make portage keep all files that ar allready built
If you want a visual representation of the parent/child relationships between processes, this is one easy way to do it. It's useful in debugging collections of shell scripts, because it provides something like a call traceback.
