1. Find the file size from 50KB to 60KB under/etc, and list the permissions in full

The answer is Find/etc-size +50k-size-60k-exec ls-l {} \;

or write find/etc \ (-size +50k-and-size-60k \)-exec ls-l {} \;

2. Find the file size greater than 50KB and the file owner is not the root file name, and the permissions are fully listed

The answer is Find/etc-size +50k! -user root-exec ls-l {} \;

3. Find files with capacity greater than 1500KB and capacity equal to 0 under/etc

As the complete output is not required, the simplest answer to this question is

Find/etc-size +1500k; Find/etc-size 0k

To display the output completely, you can also write this

Find/etc-size +1500k-exec ls-l {} \;; Find/etc-size 0k-exec ls-l {} \;

But it is too cumbersome, but this command can be seen, add not escape the different meanings
