Geektool: Virtual Desktop Enhancement

I have really grabbed a huge amount of shell scripts in the past two days and I’ll give you here my experience on Geektool (with all my grabbed scripts).

What it’s GeekTool

It’s actually a preference panel and creates a layer over the desktop which can be utilized to place picture, text file and shell script output. Most of the people use the last one (shell script output) to monitor their system like cpu hogger, etc

How to install?

Follow the link here and it gives you excellent screenshot tour

Here’s my screenshot

Apple Mail unread count

My current scripts (look at the screen shot of my desktop)

Time

Day of week: date +%A

Month: date +%B

Date: date +%d

Time: date +"%I:%M"

Alternatives:

Without the '0' infront of the hours 1-9, use: date +%l:%M

24 hour clock, with seconds: date '+%H:%M:%S'

24 hour clock, without seconds: date '+%H:%M'

AM/PM: date +"%p"

Date:

"date +"%A %d %b" (which results in Monday 12 June)

Time:

"date +"%I:%M %p" (which results in 11:30 pm)

If you want a 24 hour clock (e.g. 03:00 a.m.) then replace %I with %H. If you want to add seconds there, add %S to the mix. Remember to change the refresh rate to every 1 second if you’re adding seconds.

Short: Only shows 3 letters of the day. for example 'Wed' instead of 'Wednesday'?

date +%a

Timezones

Just change the names and GMT value to get the required clock.

TZ=US/Hawaii date +"Hawaii : %I:%M %p %a"

TZ=Etc/UTC-8 date +"Maylasia : %I:%M %p %a"

TZ=Canada/Pacific date +"Vancouver: %I:%M %p %D"

TZ=Africa/Johanessburg date +"Africa: %I:%M %p %D"

TZ=England/GMT date +"London:%l:%M %p on %d %B"

TZ=Germany/GMT-1 date +"Frankfurt:%l:%M %p on %d %B"

TZ=Australia/GMT-11 date +"Melbourne:%l:%M %p on %d %B"

TZ=NewZealand/GMT-13 date +"Wellington:%l:%M %p on %d %B"

TZ=Alaska/GMT9 date +"Anchorage: %I:%M %p - %D"

TZ=NewYork/GMT5 date +"New York: %I:%M %p - %D"

TZ=England/GMT date +"London: %I:%M %p - %D"

TZ=Australia/GMT-10 date +"Sydney: %I:%M %p - %D"

TZ=IST/UTC-5:30 date +"Chennai: %I:%M %p %a"

Last Timemachine backup

save it as timemachine.rb, +x permissions, then configure in geektools as necessary. Can probably get it down to hours if you need it that badly.

#!/usr/bin/env ruby

require 'date'

date =`head /var/db/.TimeMachine.Results.plist | grep date| awk -F'<|>|T|:|Z' {'print $3'}`.chomp.split("-")

gap = (Date.new(Time.now.year,Time.now.month,Time.now.day) - Date.new(date[0].to_i,date[1].to_i,date[2].to_i) )

if gap > 14

puts "you gotta backup. its been #{gap.to_i} days"

else

puts "na, you're cool. its only been #{gap.to_i} days"

end

-----------------------------

Can you make it show hours and days? IE: It has been 4 days and 3 hours since last?

Done

----

#!/usr/bin/env ruby

# require 'date'

public

def to_seconds; self; end

def to_minutes; self/60.0; end

def to_hours; self/(60*60.0); end

def to_days; self/(60*60*24.0); end

def to_weeks; self/(60*60*24*7.0); end

def days; self * 60 * 60 * 24.0; end

date =`head /var/db/.TimeMachine.Results.plist | grep date| awk -F'<|>|T|:|Z' {'print $3 "-" $4'}`.chomp.split("-")

gap = (Time.local(Time.now.year,Time.now.month,Time.now.day,Time.now.hour) - Time.local(date[0].to_i,date[1].to_i,date[2].to_i,date[3].to_i) )

days = gap.to_days.to_i

hours = (gap - days.days).to_hours

if days > 14

puts "you gotta backup. its been #{days} days and #{hours} hours"

else

puts "na, you're cool. its only been #{days} days and #{hours} hours"

end

Weather

Go to yahoo weather in web browser and search for your city. Now you have to search for some code in address bar (URL), it looks like this "GMXX0154". Copy the code and replace "GMXX0154" it in the following script

Current weather

curl --silent "http://weather.yahooapis.com/forecastrss?p=GMXX0154&u=c" | grep -E '(Current Conditions:|C<BR)' | sed -e 's/Current Conditions://' -e 's/ //' -e 's///' -e 's/<\/b>//' -e 's/ //' -e 's/<description>//' -e 's/<\/description>//'

Forecast

curl --silent "http://xml.weather.yahoo.com/forecastrss?p=GMXX0154&u=c" | grep -E '(High:)' | sed -e 's/ //' -e 's///' -e 's/<\/b>//' -e 's/ //' -e 's/ //'

curl --silent "http://xml.weather.yahoo.com/forecastrss?p= GMXX0154&u=f" | grep -E '(Current Conditions:|F<BR)' | sed -e 's/Current Conditions://' -e 's/ //' -e 's///' -e 's/<\/b>//' -e 's/ F //' -e 's/<description>//' -e 's/<\/description>//'

Calendar

---------

Calender: cal

---------

Last Month

cal $( echo $(date +%m)-1 | bc ) $(date +%Y)

cal -m $(date -v-1m +%b)

cal $(date -v -1m ” %m %Y”)

Current Month

(today shown as ** or #)

cal | sed "s/^/ /;s/$/ /;s/ $(date +%e) / $(date +%e | sed 's/./*/g') /"

cal | sed "s/^/ /;s/$/ /;s/ $(date +%e) / $(date +%e | sed 's/./#/g') /"

cal $(date ” %m %Y”)

Next Month

cal $( echo $(date +%m)+1 | bc ) $(date +%Y)

cal -m $(date -v+1m +%b)

cal $(date -v 1m ” %m %Y”)

Month after next

cal $( echo $(date +%m)+2 | bc ) $(date +%Y)

cal -m $(date -v+2m +%b)

---------

You can add / subtract any number of months, and since it's running in the Date command, it won't have issues with the fringe months.

Calendar

cal | awk -v cday=`date "+%d"` '{ fill=(int(cday)>9?"":" ");

a=$0; sub(" "fill int(cday)" ","["fill int(cday)"]",a); print a }'

RAM usage-

echo `vm_stat | awk 'BEGIN { FS="[ :.]+"; k=1048576} { if ($(NF-2)=="of") p=$(NF-1); else if ($(NF-2)=="free") f=$(NF-1); else if ($(NF-2)=="inactive") n=$(NF-1); } END { print "RAM:", int(n*p/k)"M/"int(f*p/k)"M" }'` `du -h -I app_profile /private/var/vm | awk '{ print $1 }'`

Disk space

Disk information: df

Drive Info: df -H -l

df -h | grep disk0s2 | awk '{print "Macintosh HD:", $4, "remaining"}'

change disk0s2 accordingly, and you can add in $2 for total space, and $3 for used space.

df -hl | grep 'disk0s2' | awk '{print $4"/"$2" free ("$5" used)"}'

HD percentage used

echo "Main:" `df -h|grep disk0s2|awk '{print $5}'` change disk0s2 to your disk

$2 gives the capacity, $3 gives the used, $4 gives the free, and $5 gives the percentage used.

diskutil info disk0s2 | grep Verified > /dev/null

Network

Network connections-

netstat -ab -f inet | grep -i established | sort +4

Network activity-

echo "Network Activity:" `((netstat -Ien0 -bn && sleep 4 && netstat -Ien0 -bn) | awk '/Link/ { if (!i) { i=$7; o=$10 } else { i=$7-i; o=$10-o } } END { print int(i/4096)"/" int(o/4096)" kB/s" }') || echo "DOWN"`

for external IP: echo `curl -s checkip.dyndns.org/ | sed 's/[a-zA-Z/ :]//g'`

for internal IP(airport): ifconfig en1 | grep broadcast| awk '{print($2)}'

for internal IP(ethernet): ifconfig en0 | grep broadcast| awk '{print("Internal IP: " $2)}'

ip SHIT-

echo Internal IP: `ifconfig | grep "inet [0-9]"|grep -v 127.0.0.1 | awk '{ print $2 }'`;echo External IP: `curl -s http://checkip.dyndns.org/ | sed 's/[a-zA-Z<>/ :]//g'`;echo "";echo "Ethernet (en0):";ifconfig en0|grep "active";echo "Airport (en1):";ifconfig en1|grep "active"

Network Interfaces/External IP:

if [ "$myen0" != "" ]

then

echo "$myen0"

Apple Mail unread count

Source: http://www.macosxhints.com/article.php?story=20090327162020498

Command: osascript /path/to/mailcheck.scpt (replace with the path and name of your own AppleScript).

Script:

set newline to ASCII character 10

set finalText to ""

tell application "Mail"

set theMessages to (messages of inbox whose read status is false)

repeat with i from 1 to number of items in theMessages

set thisMessage to item i of theMessages

set fromMsg to (sender of thisMessage as string)

set subjMsg to (subject of thisMessage as string)

set finalText to finalText & "- " & word 1 of fromMsg & " " & word 2 of fromMsg & newline & " " & subjMsg & newline

end repeat

end tell

finalText

-------------------------------------------------------------------

set newline to ASCII character 10

set finalText to ""

tell application id "com.apple.mail"

set unreadCount to (get unread count of inbox)

if unreadCount > 0 then

set theMessages to (messages of inbox whose read status is false)

repeat with i from 1 to number of items in theMessages

set thisMessage to item i of theMessages

set fromMsg to (sender of thisMessage as string)

echo "M: $unreadmail";

echo "-----";

unreadnews=`/usr/bin/osascript -e "tell application \"NetNewsWire\" to set unreadNewsCount to total unread count as string"`;

echo "N: $unreadnews";

And here’s a second one that presents it even smaller, and on one line.

#!/bin/sh

unreadmail=`/usr/bin/osascript -e "tell application \"Mail\" to set unreadCount to unread count of inbox as string"`;

unreadnews=`/usr/bin/osascript -e "tell application \"NetNewsWire\" to set unreadNewsCount to total unread count as string"`;

iTunes

AppleScript:

tell application "iTunes"

set foo1 to name of current track

set foo2 to player position

set foo3 to duration of current track

set foo4 to foo1 & " " & foo2 & "/" & foo3

end tell

I saved the above script as iTunesName.scpt. Then inside GeekTool, I set my menu-bar-sized window to run the following shell command every 10 seconds:

osascript /path/to/scripts/iTunesName.scpt

------------------------------------------------------------------------------------

Output:

iTunes: Song - Artist (Album) | rating | progress%

if there is no album then that field is dropped

if there is no rating then that field too is dropped

it will cause iTunes to open at login which I think is great!

Script:

tell application "iTunes"

set trackname to name of current track

set artistname to artist of current track

set albumname to album of current track

if albumname is null then

set albumshow to " "

else if albumname is "" then

set albumshow to " "

else

set albumshow to " ( " & albumname & " ) "

end if

set trackduration to duration of current track

set trackposition to player position

set elapsed to round (trackposition / trackduration * 100)

set myRating to round ((rating of current track) / 20)

if myRating is 1 then

set myRating to "| * "

else if myRating is 2 then

set myRating to "| ** "

else if myRating is 3 then

set myRating to "| *** "

else if myRating is 4 then

set myRating to "| **** "

else if myRating is 5 then

set myRating to "| ***** "

else

set myRating to ""

end if

set myRating to myRating

set output to "iTunes: " & trackname & " - " & artistname & albumshow & myRating & "| " & elapsed & "%"

end tell
