Run script in background
nohup [./script.sh] &

说明
nohup runs _command_ while ignoring the SIGHUP signal, so the process keeps running after the controlling terminal is closed or the user logs out. If standard output is a terminal, it is appended to nohup.out in the current directory, or to $HOME/nohup.out if that is not writable. If standard error is a terminal, it is redirected to standard output. If standard input is a terminal, it is redirected from an unreadable file. Note: nohup does not itself put the process in the background; combine with & (or a shell job-control facility) to detach.
