Can I send output from shell commands (with !) to a Matlab variable?

I sometimes use shell commands from within Matlab scripts by using ! myCommand. I was recently in a situation where I needed to manipulate the output of this command in my Matlab script. Thus my question: Is there any way to send the output from a shell command to a Matlab variable?
(I realize there's a workaround in writing to a file and reading that in to Matlab, something along the lines of
! myCommand > myFile.txt
myOutput = importdata('myFile.txt')
! rm myFile.txt
but I was wondering if there was a more elegant way.)

movefile() on Linux systems uses "mv" flag ('-p') that is not valid for NFS filesystems.
Someone (Jan?) demonstrated that some of the file-oriented commands are much slower than using the OS commands.
