updatedb for MAC OSX

MAC OSX doesn't come with an updatedb command by default, this will emulate the updatedb thats on a typical Linux OS. Simply add it to your ~/.bash_profile
This is sample output - yours may be different.

alias updatedb="sudo /usr/libexec/locate.updatedb"

Advanced ls using find to show much more detail than ls ever could

This alias is super-handy for me because it quickly shows the details of each file in the current directory. The output is nice because it is sortable, allowing you to expand this basic example to do something amazing like showing you a list of the newest files, the largest files, files with bad perms, etc.. A recursive alias would be: alias LSR='find -mount -printf "%.5m %10M %#9u:%-9g %#5U:%-5G %TF_%TR %CF_%CR %AF_%AR %#15s [%Y] %p\n" 2>/dev/null' From: http://www.askapache.com/linux/bash_profile-functions-advanced-shell.html Show Sample Output

Polkit: Force KDE apps to always recognize your display

KDE apps expect certain variables to be set, and unfortunately pkexec doesn’t set them by default. So, by setting this alias, it becomes possible to run, e.g. “pkexec kate” or “pkexec dolphin” and it’ll actually run.
This is sample output - yours may be different.

alias pkexec=“pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY KDE_SESSION_VERSION=5 KDE_FULL_SESSION=true”

Alias for quick command-line volume set (works also remotely via SSH)

If you're addicted to command-line solutions of ordinary actions or if you just want to set your volume from bed via mobile phone SSH, you can set this alias and use it as setvol 50 for setting volume on 50% gain Works only with ALSA, tested on Ubuntu 8.10. Give me some info about your experience. TIP: Try aslo command "mute" to toggle mute/unmute sound. But I don't know if this works on all distros.
This is sample output - yours may be different.

alias setvol='aumix -v'

Go up multiple levels of directories quickly and easily.

Change to your taste. Much quicker than having to add 'cd' every time. Add it to your .bashrc or .bash_profile.

Alias to securely run X from tty and close that tty afterwards.

There are different ways to run X, I prefer to run it without xdm/gdm. The problem is you can't lock X because one can press Ctrl+Alt+F1, press Ctrl+Z and kill you X locking process. Of course you can disable Ctrl+Alt* or Ctrl+Alt+Backspace keys, but it's inconvinient if you really need to switch into console.
This is sample output - yours may be different.

alias onlyx='nohup startx & disown ; exit'

zsh suffix to inform you about long command ending

make, find and a lot of other programs can take a lot of time. And can do not. Supppose you write a long, complicated command and wonder if it will be done in 3 seconds or 20 minutes. Just add "R" (without quotes) suffix to it and you can do other things: zsh will inform you when you can see the results. You can replace zenity with other X Window dialogs program.
This is sample output - yours may be different.
1

alias -g R=' &; jobs | tail -1 | read A0 A1 A2 cmd; echo "running $cmd"; fg "$cmd"; zenity --info --text "$cmd done"; unset A0 A1 A2 cmd'

Easy way to scroll up und down to change to one of <i>n</i> last visited directories.

This alias is meant to append n (here is n=10) most recently used cd commands to the bottom of history file. This way you can easily change to one of previous visited directories simply by hitting 1-10 times arrow up key. Hint: You can make more aliases implying the same rule for any set of frequently used long and complex commands like: mkisof, rdesktop, gpg...
This is sample output - yours may be different.

Creates a 'path' command that always prints the full path to any file

The command creates an alias called 'path', so it's useful to add it to your .profile or .bash_profile. The path command then prints the full path of any file, directory, or list of files given. Soft links will be resolved to their true location. This is especially useful if you use scp often to copy files across systems. Now rather then using pwd to get a directory, and then doing a separate cut and paste to get a file's name, you can just type 'path file' and get the full path in one operation. Show Sample Output
This is sample output - yours may be different.
```
path some_file.txt

/home/espider/some_directory/some_file.txt
```
1

alias path="/usr/bin/perl -e 'use Cwd; foreach my \$file (@ARGV) {print Cwd::abs_path(\$file) .\"\n\" if(-e \$file);}'"

move you up one directory quickly

Alias a single character 'b' to move to parent directory. Put it into your .bashrc or .profile file. Using "cd .." is one of the most repetitive sequence of characters you'll in the command line. Bring it down to two keys 'b' and 'enter'. It stands for "back" Also useful to have multiple: alias b='cd ../' alias bb='cd ../../' alias bbb='cd ../../../' alias bbbb='cd ../../../../' Show Sample Output
This is sample output - yours may be different.
```
~/foo $ b
~/ $
```
1

alias b='cd ../'

Redirecting bash output into any X Window

bash output is inserted into the clipboard, then mousepad is started and the clipboard content is pasted. xsel and xdotool needs to be installed. Instead of the mousepad any other editor can be used. I've successfully tested the Sublime Text Editor and it opens a new tab for each new paste. Check Sample output for a usage example.

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

mean color of an image

You can get the mean value for the colours in an image. Then you can determine, in general, how dark or bright is the image and run some other actions based on that. I'll recommend to readjust the brightness of the images using +sigmoidal-contrast option of imagemagick convert command.
