Good evening everybody,
I have to find the user owner of the most recently file in the system
How can I do? :confused:

Use the search function, there are a lot of threads regarding this topic:

Google Search Results for most recent file | The UNIX and Linux Forums

I have solved in this way:

find / -type f | xargs ls -alrt | cut -f 2 | tail -n 1

The output is:

-rw------- 1 root  operator    7111  Jun 18 22:01 /root/.viminfo

How can I obtain from this output only the owner of this file?[COLOR="\#738fbf"]

find / -type f | xargs ls -alt |  tail -n 1 | awk '{print $3}'

Hi, that would work as long as there are no spaces in the filenames, otherwise you could use something like this if your find supports print0:

find / -type f -print0 | xargs -0 ls -alt | awk 'NR==1{print $3}'

(my ls -alt has the owner in the third column)

or this if it supports printf:

find / -type f -printf "%A@ %u\n" | sort -rn | awk 'NR==1{print $2}'

Ok but the problem is to find user owner most recently file in the system

If this user is "bin" ?

My solution find it!

find / -type f -user bin -print0 | xargs -0 ls -art1 | tail -1

or

find / -type f -user bin -printf "%A@ %p\n" | sort -rn | awk 'NR==1{print $2}'
