Quick plotting of a function

The arguments of "seq" indicate the starting value, step size, and the end value of the x-range. "awk" outputs (x, f(x)) pairs and pipes them to "graph", which is part of the "plotutils" package.

ping a host until it responds, then play a sound, then exit

After this, just type: beepwhenup You need to install "beep" before this would make the beep sound. Save it in your .profile if you want to use it later WARNING: this command won't exit until it is successful. You won't be able to CONTROL+C out of it.

Countdown Clock

The biggest advantage over atoponce's nifty original is not killing the scrollback. Written assuming bash, but shouldn't be terribly difficult to port to other shells. S should be multiple spaces, but I can't get commandlinefu to save/show them properly, any help?

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.

a function to find the fastest DNS server

http://public-dns.info gives a list of online dns servers. you need to change the country in url (br in this url) with your country code. this command need some time to ping all IP in list.

search installed files of package, that doesn't remember his name well. On rpm systems

rpm, sometimes, is not wildcard friendly. To search files installed from package this could be useful. change PACKAGENAME to any package do you want to search

Insert the last argument of the previous command

for example if you did a: $ ls -la /bin/ls then $ ls !$ is equivalent to doing a $ ls /bin/ls

diff two sorted files

Sees if two records differ in their entries, irrespective of order.

Mount a VMware virtual disk (.vmdk) file on a Linux box

Assumes XP/2000/2003. For Server 2008+ try offset=105,906,176 You can find this number in the System Information utility under Partition Starting Offset. UEFI based boxes you want partition 2 since the first is just the boot files (and FAT). This works with (storage side) snapshots which is handy for single file restores on NFS mounted VMware systems

Get all possible problems from any log files

Using the grep command, retrieve all lines from any log files in /var/log/ that have one of the problem states

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

Play online music videos in terminal

pvl 'link1' 'link2' 'link3' Play Youtube, Vimeo, etc links without visual elements. Great for music videos when you just want the audio. You can control mplayer with this! Hit Ctrl-C twice to exit (if you're playing multiple files)

Show top committers for SVN repositority for today

print all network interfaces' names and IPv4 addresses

ifconfig can't properly display interface's name longer 9 symbols,also it can't show IPs added thru ip command, so 'ip' should be used instead. This alias properly shows long names, bond interfaces and all interface aliases. loopback interface is ignored, since its IP is obvious
