In this article, we'll know how to install Linux.

About Linux

Linux is an open-source operating system like other operating systems such as Microsoft Windows, Apple Mac OS, iOS, Google android, etc. An operating system is a software that enables communication between computer hardware and software. It conveys input to get processed by the processor and brings output to the hardware to display it. This is the basic function of an operating system. Although it performs many other important tasks, let's not talk about that.

Linux is around us since the mid-90s. It can be used from wristwatches to supercomputers. It is everywhere in our phones, laptops, PCs, cars, and even in refrigerators. It is very much famous among developers and normal computer users.

Syntax of Install Command

install [OPTION]... [-T] SOURCE DEST
install [OPTION]... SOURCE... DIRECTORY
install [OPTION]... -t DIRECTORY SOURCE...
install [OPTION]... -d DIRECTORY...

INSTALL: We can use the install keyword in the syntax or command. It will accept the arguments like option, suffix values, path. The install command will help to copy the data, change permissions, etc.

OPTION: We can provide the different flags as options that are compatible with the ping command.

DIRECTORY: In the install command, we can use the suffix values to reduce the number of calculations for converting the time values into a second value.

Note: The above three options are useful to copy the data from the source location to the destination location or to copy the data from multiple source locations to the destination location. It also includes the set permission and changes the ownership task. The last or 4th option is useful to create all components of the provided directory.

How does Linux Install Command work?

In Linux, there are different ways to copy the data from the source location to the destination location. Install is one of the utilities to do the same task. It does not only copy the data but also changes the ownership and change the permission as well. The install command accepts the different compatible options with location and performs the copy, owner, and permission change task.

Below are the lists of options for the install command.

  • –backup[=CONTROL]: It will backup each existing destination file
  • –b: It is similar to –backup option but does not accept an argument
  • -c: the option is used to ignore
  • -C: the option is used for the –compare. It will compare each pair of source and destination files.
  • -d: It is used for the –directory. It will treat all arguments as directory names.
  • -g: It is used for the –group=GROUP option. It will help to set the group ownership.
  • -m: It is used for the –mode=MODE option. It will help to set the permission mode.
  • -o: It is used for the –owner=OWNER option. It will help to set the ownership model.
  • -s “–strip”: It is used for the strip symbol table.
  • -S –suffix=SUFFIX: It is useful to override the usual backup suffix.
  • -t: It is helpful to copy all the source data or file into the directory.
  • -T: It will treat the destination as a normal file.
  • -v: As per the directory creation, it will print the name of each directory –verbose.
  • -P: It will help to prevent the SELinux security context.
  • -Z: It will set the security SELinux context of the destination file to be the default type.
