Compare whether the files on the shell online server are consistent

At work, you sometimes need to compare whether the files are consistent. You can use the following script (relatively simple): share it and hope to help friends who have the same requirements ~ #! /Bin/bash # compare whether files on the server are the same # Richard shen2012/07/08 # BLOG: http://lxsym.blog.51cto.comLC _ ALL = 'en _ US.UTF-8 'basedir = 'dirname $0'

Done
Echo "----------------------------------------------------------"
Done

Compare the IP address to the host.txt file, and compare the file (support multiple file types to the file.txt file)
Output result:
