NAME

grid - generate test pattern

SYNOPSIS

grid rows columns

COPYRIGHT

DESCRIPTION

Grid writes on the standard output a test pattern with the given number of rows (lines) and columns. The rows are numbered starting with 1. The columns are numbered at every multiple of 10. The leftmost column is column 1.

EXAMPLES

To find out how many columns your laser can handle in 10 point fixed-width font:

   % grid 10 100 > t1
   % cz -b 10.0bp -f t1

To get exactly 2048 bytes into a file for tape testing:

   % grid 1 2047 > t2

(The newline makes it 2048.)

Send 100 000 bytes to the terminal, and count how long it takes, in order to compute the true line speed:

   % time grid 100 999

Grid can also be used to produce a guide to column positions for text with fixed column positions.
