Or so it seems. But how you view those text files depends on what tools you're comfortable with. + +![](https://opensource.com/sites/default/files/styles/image-full-size/public/lead-images/terminal_command_linux_desktop_code.jpg?itok=p5sQ6ODE) + +There are a number of utilities that enable you to view text files when you're at the command line. One of them is [**more**][1]. + +**more** is similar to another tool I wrote about called **[less][2]**. The main difference is that **more** only allows you to move forward in a file. + +While that may seem limiting, it has some useful features that are good to know about. Let's take a quick look at what **more** can do and how to use it. + +### The basics + +Let's say you have a text file and want to read it at the command line. Just open the terminal, pop into the directory that contains the file, and type this command: + +``` +more +``` + +For example, **more jekyll-article.md**. + +![](https://opensource.com/sites/default/files/uploads/more-viewing-file.png) + +Press the Spacebar on your keyboard to move through the file or press **q** to quit. + +If you want to search for some text in the file, press the **/** key followed by the word or term you want to find. For example, to find the phrase terminal, type: + +``` +/terminal +``` + +![](https://opensource.com/sites/default/files/uploads/more-searching.png) + +Search is case-sensitive. Typing Terminal isn't the same as typing terminal. + +### Using more with other utilities + +You can pipe text from other command line utilities into **more**. Why do that? Because sometimes the text that those tools spew out spans more than one page. + +To do that, type the command and any options, followed by the pipe symbol ( **|** ), followed by **more**. For example, let's say you have a directory that has a large number of files in it. You can use **more** with the **ls** command to get a full view of the contents of the directory: + +``` +ls | more +``` + +![](https://opensource.com/sites/default/files/uploads/more-with_ls_cmd.png) + +You can also use **more** with the **grep** command to find text in multiple files. In this example, I use **grep** to find the text productivity in multiple source files for my articles: + +``` +**grep ‘productivity’ core.md Dict.md lctt2014.md lctt2016.md lctt2018.md README.md | more** +``` + +![](https://opensource.com/sites/default/files/uploads/more-with_grep_cmd.png) + +Another utility you can combine with **more** is **ps** (which lists processes that are running on your system). Again, this comes in handy when there are a large number of processes running on your system and you need a view of all of them—for example, to find one that you need to kill. To do that, use this command: + +``` +ps -u scott | more +``` + +Note that you'd replace scott with your username. + +![](https://opensource.com/sites/default/files/uploads/more-with_ps_cmd.png) + +As I mentioned at the beginning of this article, **more** is easy to use. It's definitely not as flexible as its cousin **less** , but it can be useful to know. + +-------------------------------------------------------------------------------- + +via: https://opensource.com/article/19/1/more-text-files-linux + +作者：[Scott Nesbitt][a] +选题：[lujun9972][b] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]: https://opensource.com/users/scottnesbitt +[b]: https://github.com/lujun9972 +[1]: https://en.wikipedia.org/wiki/More_(command) +[2]: https://opensource.com/article/18/4/using-less-view-text-files-command-line
