    Just don´t understand those lines and where to put colors and other stuff. Once again, thanks a lot.
    I edited the code a little bit. Nothing important so you don't need to edit yours.

    Here it is with color coding to explain the different parts:
    Code:
    cal -m | sed '1d' | sed '/^ *$/d' | sed -r '0,/./s/.*/${color BFEEFC}&${color}/' | sed 's/\<'"$(date +%-d)"'\>/${color 4CD5FF}&${color}/'|sed 's/^/${alignc -30}/'
    Removes the first line. (Month and year)
    Removes any blank lines.
    The 0 means it'll only change the first line. It adds the color to the beginning and end of the line. (Names of the days of the week.)
    Surrounds the current day number with color code.
    Adds the alignment code to the beginning of each line.

    Well, thanks-i just have to add this answer to my bookmarks. Still it is hard to know where exactly to put those values.

    Re: Conky Support Scripts: Show us your "Scripts" & Screenshots of what they do.

    Hi folks !

    For my personal use I wrote a Lua script used to transform square image to "rounded" image (ie circle with transparency).
    I also wrote a script to get images from Moon or from Earth...

    From this image to this one (in a conky)


    First, the script to get the moon or earth image : get_moon_earth.sh (to get the moon you need to pass moon as parameter). The parameters at the beginning of the script are the same as on this page : http://www.fourmilab.ch/earthview/expert.html
    Code:
    #!/bin/bash
    #This script download image from Earth or from Moon (if first parameter = "moon")
    #the parameters are the sames as on this page

    Happy conkying

    EDIT : a more simple way to have rounded images is here, with a script from larryni : http://wwww.ubuntuforums.org/showpos...ostcount=13076
    You need the 2 masks from the above topic.

    I use it now in my script, so it gives that :
    Code:
    #!/bin/bash
    #This script download image from Earth or from Moon (if first parameter = "moon")
    #the parameters are the sames as on this page

    From this image to this one (in a conky)


    First, the script to get the moon or earth image : get_moon_earth.sh (to get the moon you need to pass moon as parameter). The parameters at the beginning of the script are the same as on this page : http://www.fourmilab.ch/earthview/expert.html
    Code:
    #!/bin/bash
    #This script download image from Earth or from Moon (if first parameter = "moon")

    Hi, do you have ALSA mixer enabled in your conky, type conky -v to check.
    I am compiling version 1.8.0 and ALSA is not enabled by default, so ${mixer} doesn't work anymore ...
    I tried to compile conky with --enabled-alsa but without success, If someone can help

    Did you try last version 1.8.0 :
    http://sourceforge.net/projects/conky/files/conky/
    there are some deb for Ubuntu if you use it :
    https://launchpad.net/~norsetto/+archive/ppa/+packages

    (I didn't test them )
