How to batch replace file contents in Linux

Method 1

Use perl, the command is as follows:

find -name '要查找的文件名' | xargs perl -pi -e 's|被替换的字符串|替换后的字符串|g'

The following example is to Replace ”http://repo1.maven.org/maven2“ in all pom.xml files in the current directory and all subdirectories with ”http://localhost:8081/nexus/content /groups/public“.

find -name 'pom.xml' | xargs perl -pi -e 's|http://repo1.maven.org/maven2|http://localhost:8081/nexus/content /groups/public|g'

The Perl language is used here,

perl -pi -e Add the -e option to the Perl command, followed by a line of code, then it will Run this code like a normal Perl script.

Using Perl from the command line can help achieve some powerful, real-time transformations. Studying regular expressions carefully and using them correctly will save you a lot of manual editing work.

find -name 'pom.xml' | xargs perl -pi -e 's|http://repo1.maven.org/maven2|http://localhost:8081/nexus/content/groups/public|g'

Method 2

Use the sed command as follows:

sed -i "s/原字符串/新字符串/g" `grep 原字符串 -rl 所在目录`

A simple method to batch replace strings in multiple files under Linux. Use the sed command to batch replace strings in multiple files.

For example: I want to replace mahuinan with huinanma, execute the command:

sed -i "s/mahuinan/huinanma/g" 'grep mahuinan -rl /www'

This is currently the simplest batch replacement string command in Linux!

The specific format is as follows:

sed -i "s/oldString/newString/g"  `grep oldString -rl /path`

Example code:

sed -i "s/大小多少/日月水火/g" `grep 大小多少 -rl /usr/aa`
sed -i "s/大小多少/日月水火/g" `grep 大小多少 -rl ./`

How to make PHP container support automatic construction? Continuously integrated CI configuration method of PHP environment How to make PHP container support automatic construction? Continuously integrated CI configuration method of PHP environment Jul 25, 2025 pm 08:54 PM

To enable PHP containers to support automatic construction, the core lies in configuring the continuous integration (CI) process. 1. Use Dockerfile to define the PHP environment, including basic image, extension installation, dependency management and permission settings; 2. Configure CI/CD tools such as GitLabCI, and define the build, test and deployment stages through the .gitlab-ci.yml file to achieve automatic construction, testing and deployment; 3. Integrate test frameworks such as PHPUnit to ensure that tests are automatically run after code changes; 4. Use automated deployment strategies such as Kubernetes to define deployment configuration through the deployment.yaml file; 5. Optimize Dockerfile and adopt multi-stage construction

Building an independent PHP task container environment can be implemented through Docker. The specific steps are as follows: 1. Install Docker and DockerCompose as the basis; 2. Create an independent directory to store Dockerfile and crontab files; 3. Write Dockerfile to define the PHPCLI environment and install cron and necessary extensions; 4. Write a crontab file to define timing tasks; 5. Write a docker-compose.yml mount script directory and configure environment variables; 6. Start the container and verify the log. Compared with performing timing tasks in web containers, independent containers have the advantages of resource isolation, pure environment, strong stability, and easy expansion. To ensure logging and error capture

Linux is suitable for old hardware, has high security and is customizable, but has weak software compatibility; Windows software is rich and easy to use, but has high resource utilization. 1. In terms of performance, Linux is lightweight and efficient, suitable for old devices; Windows has high hardware requirements. 2. In terms of software, Windows has wider compatibility, especially professional tools and games; Linux needs to use tools to run some software. 3. In terms of security, Linux permission management is stricter and updates are convenient; although Windows is protected, it is still vulnerable to attacks. 4. In terms of difficulty of use, the Linux learning curve is steep; Windows operation is intuitive. Choose according to requirements: choose Linux with performance and security, and choose Windows with compatibility and ease of use.
