screenshots in linux

Use xev to determine the keycode for printscreen.

Edit ~/.fluxbox/keys to include,

118 :execCommand /home/me/bin/screenshot scr

if keycode 118 is appropriate.  Create the following file, ~/bin/screenshot:

#!/bin/bash

# from http://gentoo-wiki.com/TIP_Make_a_Screenshot_with_PrintScreen_Key

# call as screenshot scr  or  screenshot win  or  screenshot area

# Saves to folder, ~/screenshots/,  making it if required.

# Map to printscreen key, keycode 111 by mapping it to F13 in ~/.xinitrc by adding, 

# xmodmap -e "keycode 111 = F13" before fluxbox is called.

# Then add the line, 'None  F13  :execCommand screenshot scr' to ~/.fluxbox/keys

DIR="${HOME}/screenshots"

DATE="$(date +%Y%m%d@%H%M%S)"

NAME="${DIR}/screenshot-${DATE}.png"

LOG="${DIR}/screenshots.log"

# Check if the dir to store the screenshots exists, else create it: 

if [ ! -d "${DIR}" ]; then mkdir "${DIR}"; fi

# Screenshot a selected window

if [ "$1" = "win" ]; then import "${NAME}"; fi

# Screenshot the entire screen

if [ "$1" = "scr" ]; then import -window root "${NAME}"; fi

# Screenshot a selected area

if [ "$1" = "area" ]; then import "${NAME}"; fi

if [[ $# = 0 ]]; then

  # Display a warning if no area defined

  echo "No screenshot area has been specified. Screenshot not taken."

  echo "${DATE}: No screenshot area has been defined. Screenshot not taken." >> "${LOG}"

else

  # Save the screenshot in the directory and edit the log

  echo "${NAME}" >> "${LOG}"

fi

Thanks blogger, for the mangling.  This was from the gentoo-wiki, 

as mentioned above.
