What happens after i ctr+c during a nohup through ssh?

Question

I've some questions about nohup. Below shows the commands and results i've tried. If i have to use nohup ... & and then disown, then what's the use of the nohup? I could have simply use ... & and then disown.

Run a command with nohup and then ctr+c , the command didn't continue

$ nohup somecommand -option inputfile > outputfile
nohup: ignoring input and appending output to `nohup.out'
^C

Run command with nohup ... & and then ctr+c, the command continues but stops after exit

$ nohup somecommand -option inputfile > outputfile &
nohup: ignoring input and appending output to `nohup.out'
^C
$ exit

Run command with nohup ... & and then ctr+c, the command continues even after exit

$ nohup somecommand -option inputfile > outputfile &
nohup: ignoring input and appending output to `nohup.out'
^C
$ disown
$ exit

Run command with without nohup and then ctr+c, the command continues even after exit

$ somecommand -option inputfile > outputfile &
nohup: ignoring input and appending output to `nohup.out'
^C
$ disown
$ exit

Answer 1

Make sure you redirect stdout and stderr both using nohup and &

nohup somecommand -option inputfile > outputfile 2>&1 &
exit

command would still be running.
