In Linux, replace the strings-sed and grep in a certain type of files in batches.

When I modified the spec configuration file packaged by rpm today, I encountered a problem:You need to set around 100Source codeThe version number in the release row in the spec configuration file is replaced with the macro variable % {_ release }..

If you want to manually modify it, you need to modify it more than 100 times, but using the SED and grep commands is simple:

 
Sed-I "s/release: 1/release: % {_ release}/g" 'grep release: 1-rl -- include = "*. spec "./'
 

The above command is to be verified. I have written it for the time being. I will confirm it tomorrow and try again.

A simple method to replace strings in multiple files in batches in Linux.

You can use the SED command to replace strings in multiple files in batches.

Sed-I "s/original string/New String/g" 'grep original string-rl directory'
For example, if you want to replace mahuinan with huinanma, run the following command: sed-I "s/mahuinan/huinanma/g" 'grep mahuinan-RL/WWW'
This is the simplest string replacement command in Linux!
The specific format is as follows:
Sed-I "s/oldstring/newstring/g" 'grep oldstring-RL/Path'
InstanceCode: Sed-I "s/size/Sun/month/g" 'grep size-RL/usr/'
Sed-I "s/size/Sun/month/g" 'grep size-rl ./'
