Stdout

SlacUser · 06-27-2007, 06:55 PM

I want to check if my file system is alright
I run fsck /dev/sda8, and the result went to the stdout file

Now I want to check the stdout file with the cat command, but it get stuck, after several minutes and didn't show anything.

Is there a especial way to read the file or what??

I have never seen a "stdout" file.

If you run a command in a terminal, "standard output" is the terminal---ie it displays on the screen. If you have a file named "stdout", how big is it? Does it have ANY data?

To purposely put the output of fsck into a file:

fsck /dev/sda8 >filename 2>&1 (this sends (re-directs) stdout to filename, and sends stderr to the same place)

Note that there is actually a file called "stdout". It's in /dev and is a special device file.
Any text sent into this file gets printed on your shell's stdout (terminal typically).

"cat /dev/stdout" doesn't do much good, since "cat" will try to read from a device that's normally used for writing (ie writing to your terminal window) only.

Aha!!!!
If that is the file he was looking at, it all makes sense. OP--where are you??
