Is there any way to see all the owners from current directory and file name in huge concurrent logs (without ls)

Question

For my current issue I require listing all the files which have a different owner than the current owner. We have almost 600 000 files in current directory and ls -l or any other ls command will give us trouble.

[system@support forms]$ pwd
/u01/system/reports/foms
[system@support forms]$ ls -ltr|more 
total 22066 
-rwxrwxrwx 1 system sys 94208 Feb 5 2016 UTIL_COGS.rdf 
-rwxrwxrwx 1 system sys 417792 Feb 5 2016 UTIL_AL.rdf 
-rwxrwxrwx 1 system sys 212992 Feb 10 2016 UTIL_PE_BATCH.rdf

What do we need to show the files which do not have the expected owner?

Answer 1

You can use the find command:

 find . ! -user system

It will show all files not owned by system in the current directory.

You can also choose to see recent files: -mtime -10 will show only files modified less than 10 days ago.

 find . -mtime -10 ! -user system

You can also restrict to files only, avoiding to display directories with -type f:

 find . -mtime -10 -type f ! -user system
