Give an example use of the nohup command

[Mrcrysis2000]

Hi 

 

I understand what nohup command is about but im struggling to find out when it could be used? or a useful example when the parent process it terminated 

 

Any help?

so like if a script throws a error you can use it to log the error.

 

so like hohup script.pl

the nohup command is used to detach a command from the terminal's lifespan

when you launch a program from a terminal, the program is bonded to the terminal. this means that if you close the terminal, the program closes too.

nohup avoids this behaviour, allowing you to launch a program and then close the terminal

 

for example, if you want to run a program as a daemon in the background you could do it like this

nohup ./program &

where the ampersand is used to put the program in the background

 

so like if a script throws a error you can use it to log the error.

 

so like hohup script.pl

i guess that he's referring to the fact that the output of the program gets redirected to a file called "nohup.out" in the current directory

that's just a side effect, if you want to redirect the output you can just redirect stdout using the ">" operator
