PrintF and AWK => Center Alignment?
Alright, I'm relativly new to the Unix enviroment and C in general. I'm writing a script for AWK to search through a file and return what it finds with a center alignment, but so far, I can't get it to work. If anyone could help me out, I'd really appreciate it.

Ruby:
Code:
"xxx".center(9)
    ==>"   xxx   "

Awk:
Code:
BEGIN {
  print ">" center( "xxx", 9 ) "<"
}

function center( str, n    ,left,right )
{ right = int((n - length(str)) / 2)
  left = n - length(str) - right
  return sprintf( "%" left "s%s%" right "s", "", str, "" )
}
