what does this command do if it was executed in my current working directory that has files in it?
ls 2> result
I think whatever ls writes will be redirected to the result file?
Is that correct and will it redirect everything for stderr and stdout? Or only stderr?
ls command does listing of given directory. Only ls lists current directory's contents. > and 2> are IO Redirection tools. > is used to redirect stdout - standard output. 2> is for stderr - standard error. So:
user@linux:~$ ls 2> result
will redirect errors of ls command to file named result. To redirect both (error and output), you need to use:
user@linux:~$ ls >>result 2>&1
It will redirect and append stdout and stderr to that file.
Good luck!
