Top Forums Shell Programming and Scripting Field Separator in printf (awk) Post 302871365 by Don Cragun on Wednesday 6th of November 2013 04:08:22 AM

In addition to what has already been said, you're not looking for a field separator, you're looking for a field fill character. There are several ways to do this, here are two:
Code:
awk '{printf("%s%s%s\n", $1, substr("---------------", length($1)), $2)}' file
awk '{printf("%16.16s%s\n", $1 "---------------", $2)}' file

Both of these assume that 1 <= length($1) <= 15.

Both produce the output:
Code:
some------------data
here_is_more----information

when given your sample input.
