Run Application using Command without blocking Terminal
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I have made some command (at /usr/bin) to Run Application like Matlab, Weka etc in Ubuntu 18.04 LTS. While using Matlab command, it holds the Terminal until I close Matlab or Terminal (if I close Terminal, Matlab also closed). How can I avoid this problem, that means Matlab command will not hold terminal while working? Thank You.
The Following Format has worked before but suddenly not working.
#!/bin/bash
setsid /usr/local/MATLAB/R2018a/bin/matlab </dev/null >/dev/null 2>&1 & disown
Now Matlab just open the logo but no further work going on....

In this case nohup [CMD] & is a good alternative. nohup frees the command from the terminal running it and makes it immune to terminal hangups.
Also, the command you posted opens a new session and immediately sends EOF with </dev/null which forces matlab to not accept any input from terminal. This might be an issue depending on how a given program executes upon opening. I also do not think disown serves any purpose here, as the & runs it in the background and setsid should free it from the terminal. disown does not disconnect the program from the terminal, it only removes it from the job list. In any case, I'd use nohup [CMD] & as it does
1) separate the program from the terminal running it
2) closes standard input
3) redirects stdout and stderr to a separate file for examination instead of just sending it into the /dev/null abyss
4) & at the end puts it in the background
