Do PHP programmers want to learn Linuxshell programming?

Php Chinese network (www.php.cn) provides the most comprehensive basic tutorial on programming technology, introducing HTML, CSS, Javascript, Python, Java, Ruby, C, PHP, basic knowledge of MySQL and other programming languages. At the same time, this site also provides a large number of online instances, through which you can better learn programming... Reply content: learn, why not.
The problem is what it has to do with php programmers. if you like to learn it, do you have to give me a story similar to "ten benefits of shell programming for php programmers?

A programmer is so utilitarian that he likes to learn it. it may not be easy to use shell, but it does not take much time to learn a syntax. if you learn more, you will not get pregnant. When using php to write scripts, there are often some bottlenecks (you can write, but some things are more efficient with shell), such as file operations, using php to process 2. I often use some mixed processing methods. in php, popen some commands and execute a php in shell. In linux, shell or python is a very common scripting language.
There is only one reason to learn the script: Don't Repeat Yourself. you can solve the problem without learning shell. After learning shell, you don't need to solve the problem repeatedly. It is necessary not to be confined to one language. Bash shell is odd. you can learn python, which is relatively simple and easy to use. it is also a more common scripting language. Linux Shell can be understood as a Linux server command set. If you are able to access server O & M, it is inevitable to package commands to minimize repetitive work (of course, you can replace Shell with Python and Perl ); otherwise, as a PHP programmer, there is no need to worry about the depth of learning Shell. at the language and syntax level, there is no essential difference between them, it is like English and Chinese, but the application scenario is different. If the background script is developed and the application scenario is Chinese, you do not have to learn how to master Shell, but what Daniel sums up, rather than just learning. Yes, I have been interviewing companies with linux and shell knowledge questions,
