  • Get ethX mac addresses

    I much prefer using /sbin/ip over /sbin/ifconfig for most everything. I find the interface and output to be much more consistent and it has many abilities that ifconfig, route, etc. do not. To get the mac address for only one interface, add 'show dev [interface]' to the 'ip link' part of the command: ip link show dev eth0 | grep 'link/ether' | awk '{print $2}' . Also, both this command and the ifconfig one do not require root access to run, so the sudo is not necessary. Show Sample Output


    1
    ip link | grep 'link/ether' | awk '{print $2}'

  • Get your external IP address with the best commandlinefu.com command

    This command uses the top voted "Get your external IP" command from commandlinefu.com to get your external IP address. Use this and you will always be using the communities favourite command. This is a tongue-in-cheek entry and not recommended for actual usage.


    -1
    eval $(curl -s http://www.commandlinefu.com/commands/matching/external/ZXh0ZXJuYWw=/sort-by-votes/plaintext|sed -n '/^# Get your external IP address$/{n;p;q}')

  • Get your external IP address with a random commandlinefu.com command

    There's been so many ways submitted to get your external IP address that I decided we all need a command that will just go pick a random one from the list and run it. This gets a list of "Get your external IP" commands from commanlinefu.com and selects a random one to run. It will run the command and print out which command it used. This is not a serious entry, but it was a learning exercise for me writing it. My personal favourite is "curl icanhazip.com". I really don't think we need any other ways to do this, but if more come you can make use of them with this command ;o). Here's a more useful command that always gets the top voted "External IP" command, but it's not so much fun: eval $(curl -s http://www.commandlinefu.com/commands/matching/external/ZXh0ZXJuYWw=/sort-by-votes/plaintext|sed -n '/^# Get your external IP address$/{n;p;q}') Show Sample Output


    3
    IFS=$'\n';cl=($(curl -s http://www.commandlinefu.com/commands/matching/external/ZXh0ZXJuYWw=/sort-by-votes/plaintext|sed -n '/^# Get your external IP address$/{n;p}'));c=${cl[$(( $RANDOM % ${#cl[@]} ))]};eval $c;echo "Command used: $c"

  • Make sure a script is run in a terminal.

    If your script needs to be run in a terminal, this line at the top will stop it running if you absent-mindedly double-click the icon, perhaps intending to edit it. (Of course this won't help with scripts that run in the background.)

  • geoip information

    Not my script. Belongs to mathewbauer. Used without his permission. This script gives a single line as shown in the sample output. NOTE: I have blanked out the IP address for obvious security reasons. But you will get whatever is your IP if you run the script. Tested working in bash. Show Sample Output

Get AWS temporary credentials ready to export based on a MFA virtual appliance
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

Test scenario: * Open xterm (or konsole, ...) * Start xeyes with: ( xeyes & ) * Close the xterminal The xeyes process should be still running.

Find ulimit values of currently running process
When dealing with system resource limits like max number of processes and open files per user, it can be hard to tell exactly what's happening. The /etc/security/limits.conf file defines the ceiling for the values, but not what they currently are, while $ ulimit -a will show you the current values for your shell, and you can set them for new logins in /etc/profile and/or ~/.bashrc with a command like: $ ulimit -S -n 100000 >/dev/null 2>&1 But with the variability in when those files get read (login vs any shell startup, interactive vs non-interactive) it can be difficult to know for sure what values apply to processes that are currently running, like database or app servers. Just find the PID via "ps aux | grep programname", then look at that PID's "limits" file in /proc. Then you'll know for sure what actually applies to that process.

Create a git alias that will pull and fast-forward the current branch if there are no conflicts
This command will first add an alias known only to git, which will allow you to pull a remote and first-forward the current branch. However, if the remote/branch and your branch have diverged, it will stop before actually trying to merge the two, so you can back out the changes. http://www.kernel.org/pub/software/scm/git/docs/git-pull.html Tested on git 1.5.6.1, msysgit (Windows port) Actually this is not really the way I want it. I want it to attempt a fast-foward, but not attempt to merge or change my working copy. Unfortunately git pull doesn't have that functionality (yet?).
