Should I run make install as root?
Doing an su to root is only necessary for installing the compiled binaries into system directories. After becoming familiar with make and its uses, you may wish to add additional optimization options passed to gcc in the standard Makefile included or created in the package you are installing.
What is the difference between sudo su and sudo?
Sudo runs a single command with root privileges. This is a key difference between su and sudo. Su switches you to the root user account and requires the root account’s password. Sudo runs a single command with root privileges – it doesn’t switch to the root user or require a separate root user password.
What the difference between make and install?
make follows the instructions of the Makefile and converts source code into binary for the computer to read. make install installs the program by copying the binaries into the correct places as defined by ./configure and the Makefile.
What is sudo make install command in Linux?
The system directories eg /usr , are reserved for the package management system to use. By definition, if you are doing make install that means you are making a local install, and if you need to do sudo make install that means you don’t have permission to wherever you are writing.
What happens after make install?
When you do “make install”, the make program takes the binaries from the previous step and copies them into some appropriate locations so that they can be accessed. Unlike on Windows, installation just requires copying some libraries and executables and there is no registry requirement as such.
Why make before make install?
make without parameters takes the ./Makefile (or ./makefile) and builds the first target. By convention, this may be the all target, but not necessarily. make install builds the special target, install. By convention, this takes the results of make all , and installs them on the current computer.
What’s the difference between Sudo-I and Su?
sudo -s runs a shell with root privileges. sudo -i also acquires the root user’s environment. To see the difference between su and sudo -s, do cd ~ and then pwd after each of them. In the first case, you’ll be in root’s home directory, because you’re root.
What’s the difference between make install and Sudo make install?

To add a user to the sudoers group, run the following command (as root or an account that already has sudo privileges):
What does Sudo-run a command as root mean?
sudo- run a command as root make- run a script to build from source Since sudo command runs the command you pass it as root, it means that the make command has super-user privileges. This means that if the makefile is malicious, or any of the scripts it may call is malicious, then it could compromise your system.
