问题 I am trying to run a code using "nohup" command with Anaconda IPython. My code runs fine (for hours) if I run it inside ipython environment like; irsacf00-debian:~/WISE_AP> ipython Python 3.6.4 |Anaconda, Inc.| (default, Jan 16 2018, 18:10:19) Type 'copyright', 'credits' or 'license' for more information IPython 6.2.1 -- An enhanced Interactive Python.

Telling nohup to write output in real-time

阅读更多关于 Telling nohup to write output in real-time

问题 When using nohup the output of a script is buffered and only gets dumped to the log file (nohup.out) after the script has finished executing. It would be really useful to see the script output in something close to real-time, to know how it is progressing. Is there a way to make nohup write the output whenever it is produced by the script? Or, since such frequent file access operations are slow, to dump the output periodically during execution? 回答1: There's a special program for this:

问题 I have a bash script that will run in both Linux and Mac OS X. One particular line of the script works as is in Linux, but not in OS X. nohup <utility> <arg> > output.txt 2> error.txt </dev/null & When the bash script runs in Linux, it works like a charm. However, running the bash script in OS X, I get the error nohup: can't detach from console: Inappropriate ioctl for device I've done a lot of searching and haven't found a suitable answer as to why this is behaving as such.

微信公众号： 51码农网专业编程问答社区 www.51manong.com 查看huponexit对应的值，通过下面查询 [root@ky35z etc]# shopt | grep onexit 你的结果应该会返回 huponexit on。会导致nohup失效，将其设置为off [root@ky35z etc]# shopt -u huponexit session 退出的时候，不会把SIGHUP信号发给”后台任务” 来源： CSDN 作者： 51码农链接： https://blog.csdn.net/yunxiaoxiehou/article/details/103463673

在我们日常工作中, 总是不可避免的需要将进程放置后台运行, 于是我们就会使用& 或者nohup ... &, 我们有时会疑虑, 其实为什么多余添加一个nohup, 于是就是谷歌/百度, 然后就会得出一个答案: nohup 能够避免在终端断开时, 后台进程被杀掉. 但为什么nohup能够实现这个? 我们先来看下bash 对& 和nohup的解析吧: & If a command is terminated by the control operator &, the shell executes the command in the background in a subshell. The shell does not wait for the command to finish, and the return status is 0. Commands separated by a ; are executed sequentially; the shell waits for each command to terminate in turn. The return status is the exit status of the last command executed. nohup Run COMMAND, ignoring hangup signals

问题 Why doesn't the following work? $ alias sayHello='/bin/echo "Hello world!"' $ sayHello Hello world! $ nohup sayHello nohup: appending output to `nohup.out' nohup: cannot run command `sayHello': No such file or directory (the reason I ask this question is because I've aliased my perl and python to different perl/python binaries which were optimized for my own purposes; however, nohup gives me troubles if I don't supply full path to my perl/python binaries) 回答1: Because the shell doesn't pass
