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.

Replace spaces with newlines

This command is useful for separating a text file where all the words are in one line. Any group of spaces will be replaced with a single newline. Instead of one long line of tokens. You'll have a long list of tokens. One token per line.

What others think

2 problems with that.

1. useless use of cat

2. use of perl

how about:

tr -s ' ' '\n' file.txt

i like xargs for this

xargs -n1 < file.txt
Comment by novas0x2a 223 weeks and 4 days ago

Damn novas0x2a, that's why I hate man pages, you read stuff in there :

--max-args=max-args -n max-args Use at most max-args arguments per command line. Fewer than max-args arguments will be used if the size (see the -s option) is exceeded, unless the -x option is given, in which case xargs will exit.

and I still can't understand how it works.
