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.
If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/
You can sign-in using OpenID credentials, or register a traditional username and password.
First-time OpenID users will be automatically assigned a username which can be changed after signing in.
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 use a simple cat to accomplish the same task:
cat file1 file2 file3@chay, a simple cat will give you a file which contains the contents of the files in single line. I wouldn't post it if it was simple replacement for "cat".
please compare results of:
cat <(seq 1 11) <(seq 10 20) <(seq 20 30) <(seq 30 40)and
paste <(seq 1 11) <(seq 10 20) <(seq 20 30) <(seq 30 40)
