I have had people ask for hostgroups, so you could do:
parallel --nonall -S @webservers uptime
or similar.
I am considering how that could be implemented. Maybe introduce
~/.parallel/groups:
@group sshlogin1 sep sshlogin2 sep sshlogin3
sep should be a separator, that will never be in an sshlogin - maybe ;
Maybe it should be possible to do:
parallel --nonall -S @*.example.com uptime
which would run uptime on all servers matching .example.com listed in
the default sshloginfile.
Maybe there are already tools that have the group concept with a
syntax that would easy to use?
If it was done, how would you like to see it done?
