BARCHART
========
This program makes bar charts. For example, take this file 'data':
33 This is a label
0 This is another
100
80 The line above had no label
Running './barchart -w 80 data' would produce:
33 This is a label ################
0 This is another
100 ################################################
80 The line above had no label #######################################
The script should work with any POSIX shell. However, it can only automatically
detect terminal width if the 'size' operand to 'stty' is present and the
controlling terminal is available as '/dev/tty'.
This script integrates well into pipelines. For example, this makes a bar chart
of line counts for all source files in 'src':
find -L src -type f -exec wc -l {} \; | sort -rn | barchart | less
