#### open file in new process and make the nnn not block ### Troubleshooting
The desktop file opener should take care of opening files in new processes without causing `nnn` to block. #### nnn blocks on opening files
If `nnn` does block/freeze when a file is open, then set the environment variable `NNN_NOWAIT` to any
non-zero value. Ideally nnn should not block. Unfortunately, sometimes even the same desktop opener behaves differently on different Linux desktop environments. If `nnn` does block when a file is open, set the environment variable `NNN_NOWAIT` to any non-zero value. For example,
export NNN_NOWAIT=1
