learn unix

i’ve learned unix 3 months before, beginner level but is a start :)
i had to write a shell script at work, and it took me just a weekend to complete.
ive done the dumbest mistakes that you cant imagine, but at the end they are now funny memories.. :)
my company scheduled an upper level course for me,
including administation & programming,
so achieving will be easier than i thought previously :)
