new to learning Unix?

Question

Hi!

I want to learn Unix, can some-one tell me which software should I use to learn unix from pc or notebook. I really appreciate that

Answer 1

Download Knoppix, or Ubuntu (or many other flavors of Unix).



They have a compiler with them (usually GCC, command line is 'gcc').



Basic Unix commands I use every day:

cd = change directory

ls -al = list files and all the information about them

find = find files/directories

grep = search in text/files

xargs = function to run a command on each argument (use could be something like this: ls | | xargs grep "sometext")



Other Unix commands that I use sometimes:

mkdir = make a directory

rmdir = remove directory (the full path must have no other files in it)

rm -rf = remove the entire directory and any files that are in it

ps = process show (lists the processes you have running)

jobs = get a list of jobs that you have running (including background jobs)

Answer 2

Download a copy of Ubuntu http://www.ubuntu.com/ Its free!



Then open up terminal and start exploring, and never take the gui way to do something.



Linux is a Unix style environment, so many of the things you could learn in linux (vi, emacs, bash shell scripting,apache,nfs) will directly transfer over to Unix. After you're comfortable with Linux, its a matter of picking up a book on the particular Unix you're interested in (AIX, Solaris, HPUX, etc).



Many shops today run linux environments instead of unix environments, b/c Linux runs on more platforms then Unix and has free components as opposed to purchasing various levels of operating system capability.

Go there and ask on their forums. They have a few UNIX programmers on there, but you have to understand that UNIX can apply to a variety of operating systems. Mac OSX and Linux, to name a few.
