How can I redirect nohup output to a specified file?
Your problem lies in the file permissions (or a read-only filesystem). Prepending sudo to your command can’t fix this, because only nohup dotnet application.dll is executed as root by sudo, the output redirection is done by bash with your normal user privileges.
What happens when you run nohup in shell?
So, your nohup.out will contain both standard output and error messages from the script that you’ve executed using nohup command. Instead of using nohup.out, you can also redirect the output to a file using the normal shell redirections.
How can I Save my nohup command as a file?
If standard output is a terminal, append output to ‘nohup.out’ if possible, ‘$HOME/nohup.out’ otherwise. If standard error is a terminal, redirect it to standard output. To save output to FILE, use ‘nohup COMMAND > FILE’.
Where does the standard output go in nohup?
By default, the standard output will be redirected to nohup.out file in the current directory. And the standard error will be redirected to stdout, thus it will also go to nohup.out.
How to redirect stderr to a file in Ubuntu?
Redirect stdout to one file and stderr to another file: command > out 2>error Redirect stdout to a file (>out), and then redirect stderr to stdout (2>&1): command >out 2>&1
How to redirect stdout to another file in terminal?
The classic redirection operator ( command > file) only redirects standard output, so standard error is still shown on the terminal. To redirect stderr as well, you have a few choices: Redirect stdout to one file and stderr to another file: command > out 2>error.
Can You redirect output from strace to stderr?
Commands such as time and strace write their output to stderr by default. In case of time command, the only viable alternative is to redirect output of whole command , that is alternatively, synchronous list or subshell could be redirected if you want to separate the output ( as shown in related post ):
How to get sudo and nohup to work together?
You must use sudo first, nohup second. First of all, you should switch sudo and nohup . And then: The echo Starting can be replaced by any command that does not do much. I only use it as dummy command for the sudo. By this the sudo in the if-condition triggers the password-check.
Can you run a nohup command over SSH?
It does start remote process with nohup and exits ssh session immediately. It appears, that bash itself performs detaching from terminal, so no nohup needed. I run Ubuntu 14.04 x86_64, bash 4.3.11. Thanks for contributing an answer to Ask Ubuntu!
Is the ECHO command the same as Sudo?
Thus, the echo command you usually run and the echo command you run with sudo are probably two different, but similar commands. – kojiro Dec 19 ’12 at 13:48 If that is the case, why did the answers to this question suggest echo? askubuntu.com/questions/840431/… – Harsha Feb 26 ’17 at 13:12
Why do you use ” nohup ” rather than ” exec & “?
The shell built in command exec replaces the shell with , no new process, no new PID is created. After completion of normally your terminal will close. By running it in the background first a subshell is created, which then similarly is immediately replaced by .
Is it safe to close input in nohup?
While closing input has no effect on the creation or not of nohup.out, it avoids another problem: if a background process tries to read anything from standard input, it will pause, waiting for you to bring it back to the foreground and type something. So the extra-safe version looks like this:
