Re: GNU Parallel Bug Reports --ssh 'autossh' not working and --ssh 'autossh -M {PORT} not expanded

[Marco Tamassia]

My use case is tightly related to how autossh operates.
In autossh you specify a port that the software uses for monitoring the ssh connection (I don't know the internals).
Since I am going to have more than one connection, I need to specify different numbers for each remote call.
For example, normally you would do autossh -M 20000 HOST sleep 60, but if you wanted to have other parallel calls to the same host you would probably to call them autossh -M 20001 HOST sleep 60, autossh -M 20002 HOST sleep 60, ...

My idea was to call parallel as follows:

echo 20000 20001 20002 | parallel --ssh 'autossh -M '{} --sshlogin HOST sleep 60

I assume, you are referring to

since more of these connections will be launched in parallel, I need to
parameterize the arguments to autossh so that different ports are used
for parallel connections. The argument would look like --ssh 'autossh -M
{PORT}, but this is currently not expanded.

I don't understand what you try to achieve. Why should ssh and the
command you want to execute on the remote take the same argument(s)?
