Simon's Bash

[Simon]

Oh were you expecting a party?

Sorry this is about bash scripts I made up I found quite usful;

This first script I named Screen.sh was used to replace the KRandRTray I was using. I already knew the resolutions I wanted to use so what is the point to having 320x240 on that list? Also KRandRTray has an annoying revert back timer. Ugh, why ask twice? I probably don't need lines 12 and 13 but I like idiot proofing. If you plan to use this script you need to replace the resolutions for your system and you need to set the output to your output. After this was done I made up a desktop shortcut with a pretty icon and stuck it on my panel at the bottom of the screen.

 #!/bin/bash 
ScreenRes=`kdialog --radiolist "Select Screen Resolution:" 1 1360x768 on  2 1280x768 off 3 1024x768 off 4 800x600 off`
case $ScreenRes in
    1) xrandr --output default --mode 1360x768
       ;;
    2) xrandr --output default --mode 1280x768
       ;;
    3) xrandr --output default --mode 1024x768
       ;;
    4) xrandr --output default --mode 800x600
       ;;
    *) exit
       ;;
esac

For those of us who like to wine (you know who you are) this script pulls the icons from the MS executable and makes compatible PNG formats.

#!/bin/bash
#Tool use to extract MS Windows icons and convert them to PNG
exefile=`kdialog --getopenfilename '*.exe'`
#Strips out the name of the file
nameonly=$(basename "$( readlink -f "$exefile")")
#Strips out the filepath
filepath=$(dirname "$( readlink -f "$exefile")")
#Saves to the same directory as the executable
wrestool -x -t 14 "$exefile" > "$filepath/$nameonly.ico"
convert -alpha on "$filepath/$nameonly.ico" "$filepath/$nameonly.png"
#Removes the unused icon file
rm "$filepath/$nameonly.ico"

A more streamline version of that same would be;

#!/bin/bash
#Tool use to extract MS Windows icons and convert them to PNG
exefile=`kdialog --getopenfilename '*.exe'`
#Saves to the same directory as the executable
wrestool -x -t 14 "$exefile" > "$exefile.ico"
convert -alpha on "$exefile.ico" "$exefile.png"
rm "$exefile.ico"

I will be adding more below, so I don't go making a mess on the forum.

Enjoy!

Handy. Thanks for posting! Looking forward to more Simon Bashing.

[Simon]

Wow six months already? Where does the time go...

I really do love the features in Ksnapshot it is a great program with a few bells and whistles. But if you want to make your own simple version;

#!/bin/bash
#
# This shell script requires and uses: import
#Version: ImageMagick 6.6.9-7 2012-08-17 Q16 http://www.imagemagick.org
#Copyright: Copyright (C) 1999-2011 ImageMagick Studio LLC

#Variables could be added using a Kdialog but these are set to take
#a picture in the center of my 1360x768 display.
crx=640
cry=480
posx=360
posy=144
#cropped to above coordinates
import -window root -crop "$crx"x"$cry"+"$posx"+"$posy" screenshot0.png

#Active Window
activeWindow=$(xprop -root | grep "_NET_ACTIVE_WINDOW(WINDOW)")
WinId=${activeWindow:40}
import -window "$WinId" screenshot1.png

#Full Screen
import -window root screenshot2.png

That makes 3 screenshots in the directory you ran the shell program.

Fun with $RANDOM

#!/bin/bash
#
# Draws a card at random.

Suites="Clubs
Diamonds
Hearts
Spades"

Value="2
3
4
5
6
7
8
9
10
Jack
Queen
King
Ace"

#Fill the arrays
suit=($Suites)                
face=($Value)

#Is this your card? Probably not since the odds are 1 in 52.
kdialog --msgbox "${face[$((RANDOM%13))]} of "${suit[$((RANDOM%4))]}

Now all you need are the simple rules to Black Jack or if you are REAL ambitious Poker... :eek:

[GreyGeek]

Excellent examples of bash coding!

You reminded me to install bash-doc and abs-guide from the repository, to team up with Zenity (for GTK+ scripts) and Kdialog for KDE, which should be installed (if not install kdebase-bin), and the docs are here: http://techbase.kde.org/Development/...th_KDE_Dialogs.

Formating USB drive. Please heed my warning...

#!/bin/bash
#
#Simon's USB Format
#This simple shell script should work for most USB key drives.
#HOWEVER if the device fails to unmount or should it format the wrong device
#don't go blaming me. AS-IS NO idiot proofing!!
#
#Search for a removable disk
driveID=$(dmesg | grep "removable disk")

#grab 3 letter ID
DevId=${driveID:29:3}

#Drive confirmation
Confirm=$(df | grep "$DevId")

kdialog --title "Format Device" --warningyesno "Are ou sure you this is your USB device: \n"$Confirm"?"
case $? in 
    0) RootID=`kdialog --title "Root Password" --password "To proceed root access is required:"`
       ;;
    *) exit
       ;;
esac

#Unmount the Device
echo $RootID | sudo -S umount /dev/$DevId

#Menu 
FormatType=`kdialog --radiolist "Select Format:" 1 FAT on  2 FAT32 off 3 EXT3 off 4 EXT4 off`
case $ScreenRes in
    1) echo $RootID | sudo -S mkdosfs -I /dev/$DevId
       ;;
    2) echo $RootID | sudo -S mkdosfs -F 32 -I /dev/$DevId
       ;;
    3) echo $RootID | sudo -S mkfs.ext3 -I /dev/$DevId
       ;;
    4) echo $RootID | sudo -S mkfs.ext4 -I /dev/$DevId
       ;;
    *) exit
       ;;
esac

Updated and edited: I forgot to include the -S switch on all the case statement. I couldn't figure it out until I ran the script from terminal.
Repair #2: See posting below. As for bail out on blank password could be added but since this script is kind of "silly" in my opinion... uh yeah.

Edit #3 What I mean by "silly", IF I were to implement this on my system, it need not be so complicated.

This all I would need to do;

#!/bin/bash
#
#Simon's USB Ultra Simple Format
#This example has the password in the script. 
#HOWEVER this is not my password

#Unmount the Device - I don't need variables or menu if I know what I am doing.
echo "P455W0RD" | sudo -S umount /dev/sdc
echo "P455W0RD" | sudo -S mkdosfs -F 32 -I /dev/sdc

[andystmartin]

Putting on my code review hat. I'm not sure the following code works as expected:

> kdialog --title "Format Device" --warningyesno "Are ou sure you this is your USB device: \n"$Confirm"?"
> case $? in
> 0) kdialog --title "Root Password" --password "To proceed root access is required:"
> ;;
> *) exit
> ;;
> esac
> RootID=$?

"$?" gets the exit status of the previous process (an integer: 0 is success, non-zero failure). What is probably wanted is to capture the output of the previous command. Perhaps something like this:

[in case statement]
PasswdString=$(kdialog --title 'Password' --password "To proceed, root access is required:")
[ after case statement]
if [ -z "$PasswdString" ]; then
exit 1 #empty password bailing out here...
fi

[Simon]

Thank you, I was thinking it was something wrong with my, echo <password> | sudo -S <command>

fixing code above now.

[Simon]

I made this one because my ATI driver interface doesn't seem to have a thermal readout.

#!/bin/bash
#
#Get the temp from the aticonfig - look for the line with a colon.
TempInfo=$(aticonfig --odgt | grep ":")
#Now convert C to F for "those who use it" 
CtoF=$(aticonfig --odgt | grep ":"|cut -d " " -f23)
Ftmp=$(echo "scale=1;((9/5) * $CtoF) + 32" |bc)
#Display in a message box
kdialog --msgbox "${TempInfo:28} / $Ftmp F"

Short and sweet and to the point. Now you can make a panel shortcut and query the temp when you need to know.

[Simon]

For very paranoid people like myself...

watch -d -n 2 "df; ls -FlAt;"

Allows you to observe file changes in real time.
Note: The "ls" command can be structured however you desire it is currently set to show long filenames and sort by most recently changed.

[SteveRiley]

That's cool.

Full time doctoring hasn't left me much "free time" to hobby with this stuff. But one of my friends wanted to know, if Linux could run scripts like Windows. Josh is pretty big on macros for his gaming needs. So I invited him over the last weekend and we kicked about and I showed him how to make some bash macros.

#!/bin/bash 
# Clicks the screen 3000 times in one minute.
# Josh wanted this so he didn't wear out his mouse playing "idle games"

for a in {1..3000} 
  do 
    xdotool click 1 
    sleep 0.02 
  done

Then he wanted to know if I could get the color from the screen;

#!/bin/sh
eval $(xdotool getmouselocation --shell)
IMAGE=`import -window root -depth 8 -crop 1x1+$X+$Y txt:-`
COLOR=`echo $IMAGE | grep -om1 '#\w\+'`
zenity --info --text=$COLOR

This result was instant so we added a timer;

#!/bin/sh  
#10 second timer
sleep 10

#same code as above
eval $(xdotool getmouselocation --shell)
IMAGE=`import -window root -depth 8 -crop 1x1+$X+$Y txt:-`
COLOR=`echo $IMAGE | grep -om1 '#\w\+'`
zenity --info --text=$COLOR

I am working up a new way to display the timer using zenity. I guess that about rounds out all you game cheating needs eh?

[woodsmoke]

Kewl!
I use Xrandr on my document processing machine/monitor.

I think that I have a pic on the forum someplace of the setup.

Here is that visual timer. The variable "count" is always in seconds. I suppose someone with the "math skills" can figure minutes.
It uses the Zenity progress bar to show the time and auto closes when finished. The hard part is to recalculate the percentage.
Ten times ten is 100 but for a 20 second timer you would want; percent=$((100-count*5))

One possible solution would be adding yet another variable; multiple=$((100/count)) just below the count.

#!/bin/sh  
#10 second visual countdown timer
count=10
until [ "$count" -eq "0" ]; 
do 
  count=$((count-1))
  percent=$((100-count*10))
  echo "#Time remaining: $(echo "$count")"
  echo $percent
  sleep 1
done | zenity --title "Timer" --progress --auto-close

[Simon]

Sorry, been busy and with Spring weather it is not time for me to be stuck inside on my PC.

This is my latest hobby in bash scripting. It was a bit of a challenge.

Here is a nice solution I use for logging on to a password protected application. This is not a browser (they remember passwords for me) and automatically login. If you are not the only person using your PC then this may not be right for you. The app is for Windows so I have to start it with WINE. But this will work with any application.

#!/bin/bash
#This first part loads the program in WINE

export WINEPREFIX="/home/system/.wine-md"
cd "/media/system/Drive D"
wine medic.exe &

#After the ampersand the script continues to execute commands 
#This section loops until it finds a window titled "Medical"

a=0
until ((a>0)) 
do
  sleep 1
  a=$(wmctrl -l | grep -c Medical)
done

#Now we make sure xdotool can see the window.
x=$(xdotool search --name "Medical")
xdotool windowactivate --sync $x
sleep 5
xdotool type mypasswordhere
sleep 0.5
xdotool key Return

This comes up with a blinking cursor in a password box and no user ID is needed. If you need to move about the screen or add a user name;

x=$(xdotool search --name "Medical")
xdotool windowactivate --sync $x
sleep 5
xdotool type myusername
sleep 0.5
xdotool key Tab
xdotool type mypasswordhere
sleep 0.5
xdotool key Return

I just find it annoying to type and retype the same password all day long. Sometimes we get stuck using someone's garbage and we just need a bit of automation to work it out. xdotool is great for mouse and keyboard automation.
