+Using more to view text files at the Linux command line
+======
+Text files and Linux go hand in hand. Or so it seems. But how you view those text files depends on what tools you're comfortable with.
+

+
+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 <filename>
+```
+
+For example, **more jekyll-article.md**.
+

+
+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.
+

+
+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.
