I have a need to
run a single command or script on many machines in a very large environment (>10k
hosts.) Please consider adding this option to the parallel command. Below is an example of running a simple command.
cat hostlist | parallel -j 25 "ssh -l root {} uptime"
Options we are looking for in the addition:
- New option to execute a command/script on list of hosts provided via filename or piped into the command
- Option to specify how many hosts command/script should be sent to at a time {i.e. only run on 25 hosts at a time for 1000 servers}
- Option to timeout the command after nnn seconds {i.e. Host is not responding}
- Option to specify username to use on target host
- Option to specify a “options” file – This will have one option per line
- Display status optionally while running
- Output related:
- the output from command/script should all accumulated in a single file
- Each line of output should have “hostname:” prefixed to all the lines
- Output should be sorted by hostname
- Hosts that didn’t respond should be provided in a separate file
If you need any clarification please contact me.
Thank you,
Mike Rochford.
