In linux, replace strings in multiple files in batches.

In linux, replace strings in multiple files in batches.

1. linux sed replaces strings in multiple files in batches

Sed-I "s/oldstring/newstring/g" 'grep oldstring-rl yourdir'

For example, replace log.txt in all files in the current directory with test. log.

Sed-I "s/log.txt/test. log/g" 'grep log.txt-rl/home'

2. the following command:
Find./-type f
This command displays all files in the current directory

The above "s | ABCD | Linux | g" is the script to be executed by perl, that is, replacing all ABCD with Linux
If you do not write the last g, "s | ABCD | Linux |" will only replace the ABCD starting with each line.
