Linux command-command grep for searching strings

grep [Options] string file name

#在文件中匹配符合条件的字符串

Options:

-I ignores case

-V excludes the specified string

The difference between the Find command and the grep command

1. Find command: Search the system for eligible file names, and if you need to match wildcard characters, wildcards are exact matches

2, grep command: In the file to search for a qualifying string, if you need to match, use regular expressions to match, regular expression is to contain matching
