OS : How does "ls * > output.txt" work ?

Question

Lets assume that i have 2 OS installed, (Linux and Windows).

Both have different file system and both have different mechanism to read/write files.

Then how both OS Shares file information?

Answer 1

The symbol '>' represents output redirection. Normally "ls" outputs the result on the screen (stdout).

But "ls * > output.txt" redirects/forces the result to be stored in the file you mentioned, i.e.output.txt. So it does not display anything on the screen and stores the result in the file output.txt.

Hope this helps.

Answer 2

'ls' will provide the list of files and folders on the current directory.

'ls *' will provide the list of files and folders and subfolders on the current directory.

'ls * > output.txt` will redirect the output (files and folders and subfolders on the current directory) to the output.txt file
