I tried to run the below command in order to procede to install a program:
$ . configure
but after few second the Ubuntu terminal close, without any message. What happened?
Thanks for your time about my issue
By doing that you're running the configure script in the current shell similar to exec bash -e ./configure or simply source ./configure .
Dot followed by a space is equivalent to the source command , but if you want to execute the configure script in the current directory , you have to add a slash between the dot and configure :
./configure
The bash first spawns a new shell then executes it in the child shell.But if you use the source command or . configure , you're actually executing it instead of the current bash process.So your terminal will get closed after that since there's no shell to give you a prompt.
