Ok, well incorporating those couple of things (I'm still using cat. I like cat. I have one!) does make a difference, it now loops for two nodes, it resets at least one of them, them closes my ssh to the header machine.
Just before my session is closed the error tcserror: Input/output error is thrown.
I have since tried nohup and disown, these do similar, they run for a couple of loops then just end.
I should add at this point I've checked and checked, there is no problem with my nodes file. So I continue to be confused.
The problem surely is I want to explicitly ignore "Connection lost', not an error. Connection lost isn't an error, is a loss of connection, it's not a return from the command.
So, now I'm very confused.
EDIT: pssh manages fine which is a python script, so it must be possible with bash surely?

Hi all
I have a while read loop that I use to process a file line by line. The reason I am using this is due the fact that I have spaces in the line and a for loop treats the space as a delimeter for the next record.
