simple nbtstat -a equivalent/alias for linux (uses nmblookup)

it's a mixed environment where I work, and since we still use WINS services, this is often a quick and dirty way for me to obtain a mac-address for a hostname. please note that nmblookup is part of the samba suite. Just another one of those nearly useless commands that is super cool when and only when you need it. Show Sample Output

```
$ nbtstat bradyr
querying bradyr on x.x.x.x
y.y.y.y bradyr<00>
Looking up status of y.y.y.y

Makes you look busy

Enhancement for the 'busy' command originally posted by busybee : less chars, no escape issue, and most important it exclude small files ( opening a 5 lines file isn't that persuasive I think ;) ) This makes an alias for a command named 'busy'. The 'busy' command opens a random file in /usr/include to a random line with vim.
This is sample output - yours may be different.
0

alias busy='rnd_file=$(find /usr/include -type f -size +5k | sort -R | head -n 1) && vim +$((RANDOM%$(wc -l $rnd_file | cut -f1 -d" "))) $rnd_file'

Clear scrollback on all participating terminals.

Syntax outside of an alias would be printf %b \\033c. This clears the screen and removes scrollback. Works on gnome-terminal and the XFCE's Terminal, and XTerm. It does clear the screen in Konsole and the Mac Terminal, but does not clear scrollback.

Play flash video in the cache (loaded) with mplayer

Alias to play flash videos with mplayer. You can replace mplayer with your favorite video player. This alias supports Chrome & Firefox's way of handling the flash plugin. It will play all the videos in the cache. Note that certain videos might never make it to the cache, if the publisher ask for them not to: they will just be loaded in RAM. A variant if you're just interested in playing the audio, for example for a music : alias flashmusic="mplayer -vo null \$(find /proc/\$(pgrep -f 'libgcfl|libflashplayer')/fd/ -printf '%p %l\n' |grep FlashXX | cut -d\ -f1)"

private mode for (bash) shell

same as "unset HISTFILE" - but the advantage is that you can "tab-complete" it and when you do, you won't mistype it (which could lead to not unsetting the HISTFILE). put the alias in the ~/.bash_profile or ~/.bashrc file in your users home directory, respawn, enjoy! :) Show Sample Output

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.

Share Your Commands

Check These Out

check open ports without netstat or lsof

Stat each file in a directory

Possible simplification of egrep-awk-sort with find and -exec with xargs.

find the longest command in your history

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"

Find the package that installed a command

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

urldecoding

My version uses printf and command substitution ($()) instead of echo -e and xargs, this is a few less chars, but not real substantive difference. Also supports lowercase hex letters and a backslash (\) will make it through unescaped

Watch the progress of 'dd'

The 'dd' command doesn't provide a progress when writing data. So, sending the "USR1" signal to the process will spit out its progress as it writes data. This command is superior to others on the site, as it doesn't require you to previously know the PID of the dd command.

SSH to a machine's internet address if it is not present on your local network

Ping machine once, waiting 1 second for response until failing. Upon fail, ssh globally, otherwise ssh locally.

Install pip with Proxy

Installs pip packages defining a proxy
