Response 1:
The response recognizes /etc/inittab as a critical file and command in the management of Runlevel services. It is true that it has a number of lines, which guide an individual on the default Runlevel that the computer should embrace during normal booting. The response is also careful to explain that there are other significant lines that guide the system on the best commands to run during certain Runlevels (Love, 2007).
Runlevel services are usually managed by a number of commands. Such commands are the init as well as telinit commands for the 3.3.3 Runlevel. The init 1 and telinit commands for 3.3.3 Runlevel are highly significant in defining the most outstanding command for changing from one level to another at any time. The success of the runlevel services is highly dependent of the computation commands in form of init 1 and telinit 1, in the running of the Linux system (Love, 2007).
Response 2:
An environment variable is a computer’s dynamic object that stores value and can be referred to by one or more software programs. Environmental variables are significant in assisting the programs to determine what directory to install files in, and determine the storage of temporary files (Bouchaudy, 2009).
An alias is a short name that the shell usually translates into another name or form of command. They are usually taken as shortcuts that guide in undertaking various computer commands. The alias is usually placed in startup files to make it easy for them to work. The example given of "/home/badams/tools/scripts/test/script1.bash" which can be followed as alias script1='/home/badams/tools/script/test/script1.bash is outstanding. The aliases and environmental variables are highly significant in streamlining their workflow. The combinations are significant defining the workflow.
