Bug while running a Shell Command remotely from another server

Question

I have 2 servers both ubuntu say serverA and serverB

I am running a shell command from serverA on the shell of serverB but it seems I need to do some escaping for the exact command to reach serverB. The command on serverB doesnt have & and anything after that. Is there anyways I can make sure exact command reaches the serverB:

I am doing this on serverA

ssh root@serverB 'processthis -a example.com/?a=1,2,3&m=a,b,c'

the actual command that needs to reach serverB is:

processthis -a example.com/?a=1,2,3&m=a,b,c

but the command that reaches there is

processthis -a example.com/?a=1,2,3

Thanks

Answer 1

Try putting a double quote around the argument to processthis.

ssh root@serverB 'processthis -a "example.com/?a=1,2,3&m=a,b,c"'

Answer 2

You should escape the & with an \ as it gets treated by bash. Try this:

sh root@serverB 'processthis -a example.com/?a=1,2,3\&m=a,b,c'
