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.

Warn: use convmv or detox if you can: they are the right tools.

But if you want to do it manually, you can use this command to find the problematic files and transliterate their accented characters to their ascii equivalent.

(Useful when doing cd backup: growisofs may fail on files which come from the old iso8859-* days.)

Functions: sed

This permit to convert an UNIX file to DOS file.

You can use it in a loop to convert multiple files, like :

for i in *.bat; do sed -i 's/$/\r/' $i; done

Note that `grep "$(ir foo)"` really doesn't save any typing, but wrapping this inside a second shell function will:

psg() { grep "$(ir \"$@\")" ;}

User: vutcovici
Functions: echo eval grep ls sed sudo tail xargs

Tail all logs that are opened by all java processes. This is helpful when you are on a new environment and you do not know where the logs are located. Instead of java you can put any process name. This command does work only for Linux.

The list of all log files opened by java process:

2010-11-08 02:45:29
User: zed
Functions: cp echo

Change the value of p to match the path where you wish to create the profile.

To run it again in the future, use the parameter --user-data-dir (which gets echoed to you when run):

chromium-browser --user-data-dir=/path/to/your/

Quick Functions:

# create a new chromium profile

new-chromium-profile() { p=~/.config/chromium/$1; cp -r ~/.config/chromium/Default $p && echo "chromium-browser --user-data-dir=$p" && chromium-browser --user-data-dir=$p; }

# runs a chromium profile

run-chromium-profile() { chromium-browser --user-data-dir=~/.config/chromium/$1; }

This is good for cleaning up log files without having to erase the entire contents of the file, and allows you to keep the most recent entries to the log only

This command will shutdown all VMs on an VMWare ESX host. First it tries to gracefully shutdown the VM. If that fails it will hard shutdown and the power off.

cat file-that-failed-to-download.zip | curl -C - http://www.somewhere.com/file-I-want-to-download.zip >successfully-downloaded.zip
2009-08-05 13:33:06
Functions: cat

If you are downloading a big file (or even a small one) and the connection breaks or times out, use this command in order to RESUME the download where it failed, instead of having to start downloading from the beginning. This is a real win for downloading debian ISO images over a buggy DSL modem.

Take the partially downloaded file and cat it into the STDIN of curl, as shown. Then use the "-C -" option followed by the URL of the file you were originally downloading.

{ 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 recipient@example.com
2010-02-24 04:18:30
User: pascalv
Functions: echo sendmail

This will send the web page at $u to recipient@example.com . To send the web page to oneself, recipient@example.com 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.
