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.

Get involved!

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.

UpGuard checks and validates configurations for every major OS, network device, and cloud provider.

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.

Print one . instead of each line

Print one . instead of each line

If you're running a command with a lot of output, this serves as a simple progress indicator.

This avoids the need to use `/dev/null` for silencing. It works for any command that outputs lines, updates live (`fflush` avoids buffering), and is simple to understand.


There are 7 alternatives - vote for the best!

Terminal - Alternatives
alias ...='while read line; do echo -n "."; done && echo ""'

this version only uses shell builtins

That's quite useful.

Now can you please delete the two duplicates, of this command, you created.

Hmm, apparently the save button for "edit" created copies for me. I've removed them, though. :-)

Comment by lgarron 217 weeks and 4 days ago

I had to leave all the backslashes out for this to work.

awk '{fflush(); printf "."}' && echo ""

@kennyld Yep, you could directly pipe into that for a script.

I like the poetic use of a "..." alias, though.
