I frequently come across the term system tool, so I wanted to understand the exact meaning of it in Linux.
Which of the following three explanations of a system tool in Linux is correct?
Is a system tool in Linux a tool that is installed for the system to use? (I don't know if the linux kernel calls tools such as
lsout of site of the terminal user.)
Or is a system tool a tool that is installed in the system via
dnfonly, for users of the system to use? This would make
dnfa system tool.
Is a system tool simply a commandline tool which means that it does not matter how the tool was installed i.e. a tool installed using
dnfis a system tool?
To provide context in which the term is used, examples of usages of the term "system tool" are in this thread
