Print a specific number of spaces

i'm looking for a command that allows me to print a specific number of spaces which i will provide.

something as simple as:
Code:
spaces=4

printf " " * $spaces

i'm looking for somethign that'll allow me to print a specific amount of spaces on a line.

can awk be used for this?

You could try it this way:
Code:
	getspace() { # NUM
	# Returns string of NUM space chars
	#
		C=0 ; out=""
		while [[ $C -lt $1 ]];do out+=" ";let C++;done
		printf "$out"
	}

Or the other:
Code:
EMPTY="$(printf '%*s' $WIDTH)"

Hope this helps

Also if you're using bash you can do:

Code:
printf -v EMPTY '%*s' $WIDTH

Which avoids loading a sub-shell and should work a little faster. The down side is it's less portable (say to ksh).

You can also try this in perl.

Code:
 perl -e 'print " " x N';

Perl's x operator repeats a string a number of times(N).
