The command sort is used to sort files line by line. Lines starting with a number go first. Lines that come next in order go alphabetical with uppercase letters appearing before lowercase ones.
Use cat to create “testsort” for the example.
~/Test>cat testsort
A line 1
a line 2
8 line 3
line 4
5 line 5~/Test>sort testsort 5 line 5 8 line 3 A line 1 a line 2 line 4
R sorts by using a random hash of keys
~/Test>sort -R testsort
a line 2
5 line 5
A line 1
8 line 3
line 4
~/Test>sort -R testsort
5 line 5
A line 1
