Spoof your wireless MAC address on OS X to 00:e2:e3:e4:e5:e6

If you want to check that the spoof worked, type the same command as earlier: ifconfig en1 | grep ether Now you will see: ether 00:e2:e3:e4:e5:e6 For the wired ethernet port: sudo ifconfig en0 ether 00:e2:e3:e4:e5:e6

Get your local IP regardless of your network interface

Shows only IP-addresses of ifconfig except 127.0.0.0/8. I fixed the script to work on more systems and configs short info /inet/!d; #grep inet /127.0/d; # grep -v 127.0 /dr:\s/d; # grep -v dr: s/^.*:$.*$B.*$/\1/ # remove everything exept between : and B

show your private/local ip address

Gets the IP addresses of all interfaces except loopback. Cuts out all of the extra text. Shorter than the other options, and much easier to type. 'ifconfig | grep cast' is enough to get the IP address, but it doesn't strip the rest of the junk out. Show Sample Output

Get your local IP regardless of your network interface

This also works on non-Linux machines. If you have GNU sed you can do it more elegantly: ifconfig | sed -n 's/^\s*inet $addr:$\?$[^\s]*$ .*/\2/;T;/^127\./d;p'
This is sample output - yours may be different.

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. 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.

Find Duplicate Files (based on MD5 hash) -- For Mac OS X

This works on Mac OS X using the `md5` command instead of `md5sum`, which works similarly, but has a different output format. Note that this only prints the name of the duplicates, not the original file. This is handy because you can add `| xargs rm` to the end of the command to delete all the duplicates while leaving the original.

Print a list of standard error codes and descriptions.

remove newlines from specific lines in a file using sed

identify NEEDED sonames in a path

This works in combination with http://www.commandlinefu.com/commands/view/10496/identify-exported-sonames-in-a-path as it reports the NEEDED entries present in the files within a given path. You can then compare it with the libraries that are exported to make sure that, when cross-building a firmware image, you're not bringing in dependencies from the build host. The short version of it as can be seen in the same output is $ scanelf -RBnq -F "+n#f" $1 | tr ',' '\n' | sort -u

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Colored SVN diff

download all the presentations from UTOSC2010

miss a class at UTOSC2010? need a refresher? use this to curl down all the presentations from the UTOSC website. (http://2010.utosc.com) NOTE/WARNING this will dump them in the current directory and there are around 37 and some are big - tested on OSX10.6.1

Ergo browsing 'pacman' queries (Arch)

Alternative1 (grep support): pacman -Ss python | paste - - | grep --color=always -e '/python' | less -R Alternative2 (eye-candy, no grep): pacman --color=always -Ss "python" | paste - - | less -R in ~/.bashrc: pkg-grep() { pacman -Ss "$1" | paste - - | grep --color=always -e "${2:-$1}" | less -R ; } pkg-search() { pacman --color=always -Ss "python" | paste - - | less -R; }

Search commandlinefu and view syntax-highlighted results in vim

Here is the full function (got trunctated), which is much better and works for multiple queries. function cmdfu () { local t=~/cmdfu; until [[ -z $1 ]]; do echo -e "\n# $1 {{{1" >> $t; curl -s "commandlinefu.com/commands/matching/$1/`echo -n $1|base64`/plaintext" | sed '1,2d;s/^#.*/& {{{2/g' | tee -a $t > $t.c; sed -i "s/^# $1 {/# $1 - `grep -c '^#' $t.c` {/" $t; shift; done; vim -u /dev/null -c "set ft=sh fdm=marker fdl=1 noswf" -M $t; rm $t $t.c } Searches commandlinefu for single/multiple queries and displays syntax-highlighted, folded, and numbered results in vim.
