Scrot<\/strong>\u00a0(SCReenshOT<\/strong>) is an open source, powerful and flexible, command line utility for taking screen shots of your\u00a0Desktop<\/strong>,\u00a0Terminal<\/strong>\u00a0or a\u00a0Specific Window<\/strong>\u00a0manually or automatically by\u00a0Cron<\/strong>\u00a0job. Scrot is similar to Linux \u2018import<\/strong>\u2018 command, but uses \u2018imlib2<\/strong>\u2018 library to capture and save images. It supports multiple image formats (JPG, PNG, GIF, etc), which you can specify while taking screen shots by using the tool.<\/p>\n

If you\u2019re using\u00a0RedHat<\/strong>\u00a0or\u00a0Debian<\/strong>\u00a0based distribution, you can use a package manager tool like\u00a0yum<\/strong>\u00a0or\u00a0apt-get<\/strong>\u00a0to install it as shown below.<\/p>\n

    $ .\/configure --prefix=\/usr<\/pre>\n
    How to Use Scrot to take Screen shots<\/h3>\n
    As I said above, scrot can capture an entire desktop, a terminal or a specific window. With the help of scrot you can also take screen shots of a shell\/terminal of a system that doesn\u2019t have a GUI support.<\/p>\n
    Take Full Desktop Screen Shot<\/h5>\n
    Let\u2019s take a entire screen shot of the Desktop, using the following command in your terminal.<\/p>\n
    $ scrot \/home\/tecmint\/Desktop.jpg<\/pre>\n
    \n
    \"Desktop<\/a><\/p>\n
    Desktop Screen Shot<\/p>\n<\/div>\n
    Take Specific Window Screen Shot<\/h5>\n
    If you would like to capture a specific area on the screen, you can use the following command with\u00a0\u2018-s\u2019<\/strong>\u00a0switch that allows you to interactively select the area with your mouse that you wish to take screen shot.<\/p>\n
    scrot -s \/home\/tecmint\/Window.jpg<\/pre>\n
    \n
    \"Take<\/a><\/p>\n
    Take Selected Window Screen shot<\/p>\n<\/div>\n
    Adjusting the Image Quality<\/h5>\n
    With the help of \u2018-q<\/strong>\u2018 switch, you can specify the quality level of the image between\u00a01<\/strong>\u00a0and\u00a0100<\/strong>. The default image level is set to\u00a075<\/strong>, and the image output will be different depending upon the file format you specify.<\/p>\n
    The following command will capture an image at\u00a090%<\/strong>\u00a0the quality of the original high quality screen.<\/p>\n
    $ scrot -q 90 \/home\/tecmint\/Quality.jpg<\/pre>\n
    \n
    \"Take<\/a><\/p>\n
    Take Quality Screen shot<\/p>\n<\/div>\n
    Take Screen Shots Automatically<\/h5>\n
    Now if you would like to get automatically screen shots, than you need to create a simple shell script. Create a file \u2018screen.sh<\/strong>\u2018 with \u2018touch<\/strong>\u2018 command and add the following content to it.<\/p>\n
    #!\/bin\/sh\r\nDISPLAY=:0 scrot 'tecmint-%Y-%m-%d-%H_%M.jpg' -q 20 && mv \/home\/tecmint\/*.jpg \/media\/tecmint<\/pre>\n
    Now grant \u2018777<\/strong>\u2018 permission and set an\u00a0Cron<\/strong>\u00a0job.<\/p>\n
    $ chmod 777 screen.sh<\/pre>\n
    Open a \u2018crontab<\/strong>\u2018 file and add the following entry. You can define custom interval time.<\/p>\n
    $ crontab -e<\/pre>\n
    *\/1 * * * * sh \/home\/tecmint\/screen.sh<\/pre>\n
    The above\u00a0Cron<\/strong>\u00a0entry will run every \u20181<\/strong>\u2018 minute and take screen shots and store them under \u2018\/media\/tecmint<\/strong>\u2018 directory with filename as date and time. After running script for\u00a01<\/strong>\u00a0minute, this is what I found in my \u2018tecmint\u2019<\/strong>directory.<\/p>\n
