What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

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.

Universal configuration monitoring and system of record for IT.

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.

You can, of course, tell MySQL to output results to a file and dictate how to terminate lines, etc. But sometimes you don't have access to the file system MySQL is running on, complicating outputting your results to a CSV, necessitating either annoying hacks or this simple command :D

Know a better way?

If you can do better, submit your command here.

What others think

Not bad, but there's one possible problem.

If the database fields contain quotes ", then the csv will be corrupt.

To fix this, prefix your sed statement with:

sed 's/"/""/g'

Also, the two sed statements to add quotes to the beginning and end can be combined (simplified) to:

sed 's/.*/"\0"/'

Finally, I don't understand when I'd need the last sed part: sed 's/\n//g'

Combining the lot, I get:

... | sed 's/"/""/g;s/\t/","/g;s/.*/"\0"/' > ...
