Use shell to monitor whether the files in the site directory have been modified

#! / bin/bash#check_file_md5 find / application/nginx/html/test1/-type f | xargs md5sum > / tmp/web_md5_f.txt#check_file_num tree-I / application/nginx/html/test1 | grep-v "^ $" > / tmp/web_md5_num.txt.defaultMD5= `/ usr/bin/md5sum-c / tmp/web_md5_f.txt | grep-v "OK" | wc-l`TREE = `tree-I / application/nginx/html/test1 | grep-v "^ $" > / tmp/web_md5_ num.txt`if ["$MD5"-ne 0] Then echo "At $(date +% F) / application/nginx/html/test1 has been changeable Please make sure!" else echo "Everything is OK!" fidiff / tmp/web_md5_num.txt / tmp/web_md5_num.txt.default

The principle of implementation is as follows

1. Monitor whether the MD5 value of the file is the same before and after. If it is different, an error will be reported when comparing md5sum.

two。 Use the tree command to output to the specified file, and use diff to compare whether the two generated contents are the same. If there are more or less files, you will be prompted.

Knowledge points:

Md5sum-c: the MD5 value can be compared before and after. If the comparison fails, it will prompt FAILED.

Tree-I: remove the tree structure and display it directly as a column
