How do you script ssh commands then background the session? -


i trying create single script starts ssh session, , execute commands on remote machine, backgrounds session. far i've been playing -f or -f -n options, don't know how bring session foreground verify commands executed correctly.

or there way single script can start ssh session , continue inputting commands newly opened session? , background session? if none of work thinking way of doing script starts ssh session, upload , execute commands via script.

any ideas on how this.

it not clear trying do. i'll try helpful.

a series of commands can issued sequentially in single ssh session using single quoted string commands separated semicolons.

$ ssh user@remotehost 'ls; echo  foo > bar; cat bar; rm bar'

it return result of last command run.

i'm confused why want background session.

if need can start long running process on remote machine nohup , close session.

if need series of commands run each depend on result of last one, don't need background process, put logic command sequence.

$ ssh user@remotehost 'if ![ -f bar ];then echo  foo > bar && cat bar && rm bar; fi'

no harm in multiple sequential ssh , scp connections if there lot of things done.
