At work whenever we need to build little command line tools, my team is always vexxed by my guideline to have the meat+potatoes in a script that reads well-formatted data off stdin , and outputs well formatted-data to stout. They always wanna have some stupid interactive prompts and saving to files baked right in.
This is exactly why. You wanna save to a file?? > file
You want to read from a file? cat |
You want to save to a file but swap commas for colons? Sed.
You get so much FOR FREE w/ the GNU toolkit, even for what you build yourself, by thinking in streams.
Based on this I can only imagine they must have full throated support of the green line which would reduce intra-city traffic to allow for greater available capacity for provincial traffic.
