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.

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.

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

This prevents access to old CGI code

while true ; do fswebcam -d /dev/video0 -r 1280x1024 -F 15 - | uuencode $(date +\%Y\%m\%d\%H\%M).jpeg | mail -s "Video surveillance" [email protected] ; sleep 300 ; done

Functions: date mail sleep true uuencode

This takes a picture (with the web cam) every 5 minutes, and send the picture to your e-mail.

Some systems support

mail -a "References: "

so that all video surveillance emails are grouped in a single email thread.

To keep your inbox clean, it is still possible to filter and move to trash video surveillance emails (and restore these emails only if you really get robbed!)

For instance with Gmail, emails sent to [email protected] can be filtered with "Matches: DeliveredTo:[email protected]"

links $( a=( $( lynx -dump -listonly "http://news.google.com" | grep -Eo "(http|https)://[a-zA-Z0-9./?=_-]*" | grep -v "google.com" | sort | uniq ) ) ; amax=${#a[@]} ; n=$(( `date '+%s'` % $amax )) ; echo ${a[n]} )

Access a random news web page on the internet.

The Links browser can of course be replaced by Firefox or any modern graphical web browser.

User: pascalv
Functions: bash mail nohup

Run "ps -x" (process status) in the background every hour (in this example).

The outputs of both "nohup" and "ps -x" are sent to the e-mail (instead of nohup.out and stdout and stderr).

If you like it, replace "ps -x" by the command of your choice, replace 3600 (1 hour) by the period of your choice.

You can run the command in the loop any time by killing the sleep process. For example

ps -x

2925 ? S 0:00.00 sh -c unzip E.zip >/dev/null 2>&1

11288 ? O 0:00.00 unzip E.zip

25428 ? I 0:00.00 sleep 3600

14346 pts/42- I 0:00.01 bash -c while true; do ps -x | mail pascalv; sleep 3600; done

643 pts/66 Ss 0:00.03 -bash

14124 pts/66 O+ 0:00.00 ps -x

kill 25428

You have mail in /mail/pascalv

{ u="http://twitter.com/commandlinefu"; echo "Subject: $u"; echo "Mime-Version: 1.0"; echo -e "Content-Type: text/html; charset=utf-8\n\n"; curl $u ; } | sendmail [email protected]
2010-02-24 04:18:30
User: pascalv
Functions: echo sendmail

This will send the web page at $u to [email protected] . To send the web page to oneself, [email protected] can be replaced by $(whoami) .

The "charset" is UTF-8 here, but any alternative charset of your choice would work.

`wget -O - -o /dev/null $u` may be considered instead of `curl $u` .

On some systems the complete path to sendmail may be necessary, for instance /sys/pkg/libexec/sendmail/sendmail for some NetBSD.
