What's behind a file descriptor in Linux? Also, i/o redirection with dup2.

[@thaianle4623]

I like your teaching style, super detailed with hand-on example

[@devmahad]

For my own reference: File descriptor is a int that store the id of file, so that we can access that later. This is store in a vnode table, that we can access using ulimit -a command. Now, we can use the output of one program, from standard input and send it to standard output. Or we can do vice versa.

May Allah bless you, I've been thinking about doing some system programming for a while now. Thanks to you, I think I'm motivated enough to jump in. I hope you will publish more videos like this in near future :) Thank you

@Chris Thanks for this video. I need a help, So, I want to see the output of a running process (a .sh script with echo statement). When I went inside the /proc//fd, and run tail -f 1, no output were seen, then I tried ls -l, I see file discriptor is linked to pipe :[XXXXXX]. Not sure what it means? And how I can see the output of fd 1 of this process

[@pranavsingh1081]

very helpful

[@edgarcalochcampos1930]

great!

[@dawnwatching6382]

But if you spawn a process on the output side of the pipe, what if it tries to read before the process on the input side of the pipe finishes? I assume it waits until there's something to read?

[@aboalesaad]

Could anyone find these slides?
