For example, to find the AAA string in the ABC catalogue. Grep-rn "AAA"/wwwroot/abc/the current directory. -R indicates recursive lookup-n for displaying line numbers VI How the open document displays line numbers Set:number Do not show line numbers Set:nonumber Jumps to a specified number of lines, such as 100 lines Enter 100G carriage return Example Find "hello,world!" String, you can do this:

Find Clevercode in the current directory and subdirectories, all PHP occurrences are greater than 0 times.# find-type f-name ' *.php ' | Xargs grep clevercode./*.php-rc | Awk-f ': ' $ > 0 {print $1,$2} ' | Grep-v '/.svn/' | Sort-n-K 2-r1) find-type f-name ' *.php '. Finds all PHP files in the current directory and subdirectories.2) xargs grep clevercode./*.php-rc. Finds the Clevercode keyword in each file and displays the number of occurrences.3) awk-

Max value friend out of a problem, each has a,b,c three people to do the game, record the first score, after dozens of games, the results are as follows: ID Name Score 1 a 88 2 B 76 3 C 66 4 C 90 5 B 77 6 a 56 7 B 77 8 C 67 9 a 44 ...... Of course, there's plenty. Ask for the best results for each of the three a,b,c, and list the number of the best grades, the ID number. Such as: ID Name Score 1 a 88
