How the shell generates RPM package warehouse list file comparison results

Basic steps:

1. Switch to the warehouse directory Rpm_list_dir1 and RPM_LIST_DIR2

2. LS lists the RPM package files of the warehouse and redirects them to the output files Rpm_list_file1 and Rpm_list_file2 respectively.

3. Output the comparison results to the diff file Difff_file

Summarize:

The seemingly tricky things in code are all erased, and sometimes you are not the others, but yourself!
