Read workstation list from file und run command

Hi,

how do I read in a file which includes a list of workstations and then run a command for each workstation ?
I am unclear which command to use to read in , or is this not possible ?

Thanks,

Example:
Code:
while read HOST; do
     ssh $HOST "ls -la"
done < hostlist

Also note that in a while loop ssh runs off with the stdin file descriptor, preventing read from reading anything else from it.

Use the -n switch to prevent reading from stdin:
Code:
while read HOST
do
   ssh -n "$HOST" "ls -la"
done < hostlist
