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.

Change the number to change the number of spaces. Leaving it out defaults to 8. Leaving out the filename defaults to stdin.

And to do it in reverse, you can use the unexpand command.

Know a better way?

If you can do better, submit your command here.

What others think

This won't work correctly if you have multiple columns.

"a<tab>b<tab>c" should expand to "a<space>b<space>c" "d<tab><tab>e" should expand to "d<space><space><space>e"

Then all three columns line up. The only sensible solution is to use the expand command:

expand -t 2 < yourfile
