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.

An improvement of the original (at: http://www.commandlinefu.com/commands/view/2872/update-twitter-via-curl) in the sense that you see a "from cURL" under your status message instead of just a "from API" ;-) Twitter automatically links it to the cURL home page.

curl -u user -d status="Tweeting from the shell" http://twitter.com/statuses/update.xml

Doesn't require password (asks for it instead)

tweet () { curl -u UserName -d status="$*" http://twitter.com/statuses/update.xml; }

This version of tweet() doesn't require you to put quotes around the body of your tweet... it also prompts you for password. It will still barf on a '!' character.

curl -u YourUsername:YourPassword -d status="Your status message go here" http://twitter.com/statuses/update.xml

Found it on snipt, pok3, is it yours?

I put my user = m33600, the password and the status was my robot message:

Settima robot message: ALARM ZONE 3 (sent via command line).

Now bots may have their identity on twitter...

tweet(){ curl -u "$1" -d status="$2" "http://twitter.com/statuses/update.xml"; }

Type the command in the terminal and press enter to create the tweet() function. Then run as follows:

tweet MyTwitterAccount "My message goes here"

It will prompt you for password. Make sure that you use escape "\" character in message for showing varialbles or markup.

Know a better way?

If you can do better, submit your command here.

What others think

Be carefull not to do that in a multi-user machine, since your password will be visible in the process listing for as long as curl is running.

If you leave out `:pass` (your password), you will be able to enter your password later in a more secure manner.

Comment by sirlancelot 316 weeks and 2 days ago

Also note that you can't use an "!" as bash will error out with

bash: !": event not found
Comment by XtCrAvE 314 weeks and 2 days ago

or $history -c once you do that... [of course to clear the hisory]

Comment by chanux 313 weeks and 4 days ago

regarding bash history and security: you can also put a space in front of a command to keep it out of your .bash_history (pressing up won't show it)

curl etc...etc...


Comment by sudopeople 313 weeks ago

This is resulting in 403 (Forbidden) errors today:

403 Forbidden: The server understood the request, but is refusing to fulfill it.

Comment by alesplin 311 weeks ago

Note: if cURL not installed, install it (ubuntu) :

sudo apt-get install curl

Comment by cmdnix 294 weeks and 4 days ago

You can use ! just use 'single quotes'

Comment by mandroid 254 weeks and 6 days ago

Just start the command with a space (if it includes your password)so that its not stored in your .bash_history file. its safer that way.

Comment by nssy 247 weeks and 3 days ago

i tried, but i get this answer:

Basic authentication is not supported

Comment by rubo77 237 weeks and 6 days ago

Twitter recently removed support for HTTP Basic Auth (requiring OAuth instead) so this command will not work anymore.

See http://dev.twitter.com/announcements

Comment by ronnix 237 weeks and 5 days ago


Basic authentication is no longer supported by @twitter

This generates error "curl -u user:pass -d status="Tweeting from the shell"

Basic authentication is not supported

Comment by ruwindada 235 weeks ago

so is there any other solution?

Comment by rubo77 231 weeks and 2 days ago

Basic Auth turned off as of August 2010: http://apiwiki.twitter.com/w/page/22554643/Authentication

Comment by dan77l 227 weeks and 4 days ago

Looks like there is a solution, gotta use OAuth: http://jeffmiller.github.com/2010/05/31/twitter-from-the-command-line-in-python-using-oauth

Comment by dan77l 227 weeks and 4 days ago

Basic authentication is not supported

Comment by ni3in3005 208 weeks and 4 days ago

Personally I'm using this mostly bash-based solution: http://blog.yjl.im/2010/05/bash-oauth.html

Here is a working bash script to post to Twitter from the command line on Linux and Mac:
