proc/interrupts

Hi guys, my name is Daniel Brown, I am working on a CS degree, and am a complete newbie to Linux. It seems quite a bit different to someone who has only used Windows, but I kind of like it so far. My question is about the proc/interrupts command, I have tried it both from user and root, and it always says no such file exists. I have tried typing it as cat/proc/interrupts, and just proc/interrupts. Do you have to change the directory you are in to use it?

The command is cat, the file is /proc/interrupts, so the entire command line is:

Code:

cat /proc/interrupts

You need a space between a command and its arguments.

The command is cat and the argument is /proc/interrupts

Code:

cat /proc/interrupts

edit, yes as hydrurga said

Yup, that did it. Told you guys I was a beginner. Thank you!

Is there a way to post pictures on here, as far as screenshots? Trying cat proc/interrupts worked once, now when I try it I am getting the same message, no such file or directory. I've tried it from both user and root.

You need to familiarize yourself on how file path works, as a shortcut

When you type

Code:

proc/interrupts

The path resolves to a interrupts file in a proc directory that is itself in current directory (relative path)

When you type

Code:

/proc/interrupts

This is absolute path, it resolves to interrupts file in proc directory that is itself in root filesystem
