Selecting lines of a file
Say I wanted to select the 5th line of a file without knowing the context of the file. Would I use grep and pipe it into wc or is there a more simple way of doing this?

awk (nawk on solaris)example: When the statement between ' and ' evaluates to true, the fifth line has just been input, it means print this line, the default awk action.
Code:
# awk
awk 'NR==5' filename

You can do oneliners with sed, perl, ruby also.

Why is it that when I do $RANDOM=variable and then when i try to echo out $RANDOM + 1 I just get the $variable + 1 and not a random number within $variable's limits?

Nevermind I answered my own question by setting a variable = to random and doing random %$variable+1
