Bulk Replace file contents under Linux

1. Ready-made information on the Internet

Format: Sed-i "s/lookup field/replace field/g" ' grep lookup field-rl path '

　　linux sed Bulk replaces strings in multiple files : (This command is very powerful)

sed-i "s/oldstring/newstring/g" ' grep oldstring-rl yourdir '

explain:

- I. represents inplace edit, in-place modify file

-R means recursive, searching subdirectories

-L = line number, output matching file name

For example: Replace the www.admin99.net in all files under/home to Admin99.net

Sed-i "s/www.admin99.net/admin99.net/g" ' grep www.admin99.net-rl/home '

Exp:sed-i "s/shabi/$/g" ' grep shabi-rl./'

2, self-added additional

2.1 Replace the text "garden" in file 1.txt with "Mirgarden"

# sed-i "s/garden/mirgarden/g" 1.txt//sed-i very simple

2.2 Replace "garden" in all files in the current directory with "Mirgarden"

# # Sed-i "s/garden/mirgarden/g" ' ls '//is actually the LS out of multiple filenames
