是shell的命令,若是咱們執行python test_nohup.py
,就會直接返回shell給用戶,且用戶不能再進行輸入。python
& puts the job in the background, that is, makes it block on attempting to read input, and makes the shell not wait for its completion.shell
但若是咱們關閉terminal,process將被關閉。只是失去了process從terminal得到輸入的能力。ubuntu
(jd) ubuntu@vmXXX:~$ python3 test_nohup.py & [1] 11698
nohup test_nohup.py
是segmentfault
nohup disconnects the process from the terminal, redirects its output to nohup.out and shields it from SIGHUP.unix
咱們仍然能夠使用ctrl+c將進程(process)殺死,但若是咱們關閉terminal,process仍然在後臺進行。但咱們沒法馬上得到shell的交互能力。code
將二者結合起來,就能讓程序在後臺運行的同時,咱們也能得到交互shell的能力。進程
