gmjosack / gsh Goto Github PK

Submitted for @timdoug

I'd like the output of a run to be aligned left against the longest hostname in a group, probably up to some reasonable max.

When I suspend gsh with ^Z and come back a minute later, all of the open SSH connections have timed out per my -t setting.

Traceback (most recent call last):

I was running a 'curl -s foo' across a number of hosts and the output file didn't have a newline, so curl faithfully only prints the output. This causes my gsh output to not have newlines, which makes it a little difficult to read.
