Thanks for this tutorial and wait the next one about bash scripting.

P.S. It would be nice if there where on your site option to save this kind of tutorials in pdf mode…I know there are addons for this but it’s an idea to implement directly in the site!

have a nice weekend!

Re: echo -e “Kernel Details: ” `uname -smr`

Command substitution is slow and, in this case, unnecessary.

Using ‘echo’ (which I don’t recommend) you could do:

echo -n “Kernel Details: ”
uname -smr

I rarely use echo because of portability problems; printf is universal:

printf “Kernel Details: ”
uname -smr

There is no good reason to use an external command (which) to find the location of a shell or any other executable file. Bash, like all Bourne-type shells, has the builtin command ‘type’.

If the command is a function or an alias, ‘which’ will not tell you that; ‘type’ will.
