The result of "ls -k" is different between RHEL7 and earlier.

Issue

• In REHL6, the -k option sets the file size unit to 1KiB.

  # ls -l test.txt
  -rw-r--r-- 1 root root 49561027 Apr 28 11:55 test.txt
  # ls -lk test.txt
  -rw-r--r-- 1 root root    48400 Apr 28 11:55 test.txt
  

• In RHEL7, no change in file size when using the -k option

  # ls -l test.txt
  -rw-r--r-- 1 root root     1746 Apr 28 11:50 test.txt
  # ls -lk shell.log
  -rw-r--r-- 1 root root     1746 Apr 28 11:50 test.txt
