Install
After building the binary, we're now going to "install" it by using the install command.
We’re actually not installing the binary though since the install command isn’t used to install software packages despite its name.
The install command is a way to copy files to a target location similar to the copy command, i.e., cp, but it gives us more control by allowing us to use advanced features when copying the files.
Some of these advanced features include the abilities to adjust permission modes like when using the chmod command, adjust ownership permissions like when using the chown command, to make backups of the files, and to preserve the metadata of the files, e.g., the access and modifications times of the files.
We're going to be "installing" the khatru29 binary to the /usr/local/bin directory which allows us to run the binary from any directory. This makes running the binary easier since we don't have to navigate to or specify the path to the khatru29 binary every time we want to run it.
First, navigate to the directory where you installed the binary, e.g.,
To "install" the binary we can run:
Here’s an explanation of the options we passed to the install command:
-v: This option specifies that we would like to see the verbose output which means we’ll be displayed with the details of the process.
-m: This option specifies the file permissions in octal notation for the files we’re copying, i.e., 0755.
-o: This option allows us to set the owner for the files we’re copying, i.e., root.
-g: This option allows us to set the group for the files we’re copying, i.e., root.
-t: This option specifies the target directory that we want to copy the specified files into, i.e., /usr/local/bin.
