What Does M Mean in Linux?

M in Linux is short for memory. It is a basic command that can be used to view the amount of free and used memory on your computer. The output of the command will show you the total amount of memory, the amount of free memory, and the amount used memory.

You can also use this command to see how much memory is being used by each process on your computer.

M in Linux can mean a lot of things! Most commonly, M is used to refer to the kernel, which is the central part of the Linux operating system. The kernel is responsible for managing hardware and providing basic services to user-space programs.

M also stands for loadable module. A loadable module is a piece of code that can be loaded into the kernel at runtime, without having to recompile the entire kernel. This makes it possible to add or remove features from the kernel without needing to rebuild it from scratch each time.

Finally, M can also refer to memory management. Memory management in Linux is handled by a subsystem called the Virtual Memory Manager (VMM). The VMM is responsible for allocating physical memory pages to processes and keeping track of what each process is using them for.

What Does M Command Mean?

M command is a computer language developed by IBM. It is a proprietary language used for business applications.

What Does ‘- M Mean in Terminal?

Assuming you are referring to the commonly used ls command, the -m flag tells ls to output the list of files in a comma separated format. This can be useful for parsing the output of ls into other programs or scripts.

What Does M Mean Unix?

M is a Unix command that displays the contents of a file or files one screen at a time. It is similar to the more common “less” command, but has some important differences. One key difference is that M allows you to scroll both forward and backward through the file using the up and down arrow keys on your keyboard, while less only allows you to scroll forward.

M also supports search features, allowing you to quickly find specific text within a file. Finally, M can be used to display multiple files simultaneously, making it a handy tool for comparing two or more files side-by-side.

What is Control M Character in Linux?

In Linux, the control M character (^M) is a carriage return. When you press the Enter key, the cursor moves to the beginning of the next line. However, in some text editors (such as vi), ^M also causes the text on the current line to be overwritten with whatever you type next.

How to Remove ^M in Linux

If you’ve ever used a text editor on Linux, you may have noticed that some lines of text end with ^M. This is because different systems use different characters to represent the end of a line. When you transfer files between systems, the ^M can show up.

There are a few ways to remove these ^M characters from your files. One way is to use the tr command. For example, if your file is called myfile.txt, you would type:

tr -d ‘\r’ < myfile.txt > newfile.txt This would create a new file called newfile.txt that does not contain any ^M characters. Another way to do this is with sed:


M stands for memory, and is a common designation for RAM (random access memory) in Linux. It can also refer to virtual memory, which is a combination of physical RAM and disk space. The M designation is used to distinguish between different types of memory in Linux.
