Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

More of the same but with more elaborate perl-fu :-)

What others think

Awk is shorter.

Awk roolz. :-)

I made a perl compatible version as wel. AWK is still shorter.

Although the actual 'script' is 1 byte shorter for perl in this representation. Condensed, awk wins:

'{x=x+$4}END{print x}'



To sum it up. Awk is more cooler then perls are ;-)

You can use '+=' in awk, it makes the command even shorter.

awk -F',' '{x+=$4}END{print x}' test.csv
