Support forwarding stdin in pdsh about pdsh

[GoogleCodeExporter]

Mark,

I vote for this, too ( presuming i wasn't the sf.net user ;) ). (i'm not just 
+1 Me Too... i have a use case here that may be of more real use than the 
md5sum example above)

Right now, i'm trying to do a simplistic encrypted password changer for the 
root account that doesn't end up putting the encrypted password onto the 
arglist for the process.

$ UMASK=077 echo "root:ENCRYPTEDPASSWD" > ${HOME}/pw.txt
$ pdsh -Rexec HOST-SPEC /bin/sh -c 'ssh root@%h /usr/sbin/chpasswd -e < 
${HOME}/pw.txt'

is the closest thing to doing this.

It'd be desireable to:

echo "root:ENCRYPTEDPASSWD" | pdsh HOST-SPEC --dup-stdin '/usr/sbin/chpasswd -e'
(presuming 'echo' is a shell builtin, or client machine is secured 
single-user...)

But, yeah, it's definitely a LOW priority item.

thanks,
--stephen

Thanks for the added use case. It is on my TODO list, but pdsh doesn't get too 
much attention lately.
