You can also change the size of the widget with a slider in settings. IE all that extra space in noobmonkeys screenshot is the default size of the widget you can shorten it and reduce the space taken. Very nice little widget by all acounts.

iv also got some free memory widgets (rootfs, mass mem and mem card), is there any command to use so i can have 1 showing free RAM? thanx



Command to show free mass memory: df -h | awk ' $1 == "/dev/mmcblk0p1" {print $4"B"}'

Command to show free memory on mem card: df -h | awk ' $1 == "/dev/mmcblk1p1" {print $4"B"}'

hehe i just have it that size to match the others - removed it now because i don't need the date - thats what my watch is for

Tis very customisable though

well there are a few ways to get free memory. the most useful for this widget would be

head -n 2 /proc/meminfo | tail -n 1

this will give you free mem in one line.

More informative is the command free that will give you more info on how it is allocated.

the command I gave is chopping one line out of the meminfo file. from an xterm type

cat /proc/meminfo

To see it all.

the field I have taken above is memfree. But I do not think that is very useful due to the way linux uses memory. Someone who knows more about the linux memory model nay be able to provide more useful info.

would there be a command that could pull time form world clock so it could display on desktop using the desktop widget?

Thanx, works a treat, but is there anyway to show it without it displaying the words 'MemFree:' so it only displays the actual free ram in kb/mb and no text, thanx again.

yes but you will have to let me get to my home PC (very late UK time tonight.) To play with it.

If someone else comes up with it meanwhile cool.

Work PC is windows so cant really experiment much.

not the most elegent solution but it should work.

head -n 2 /proc/meminfo | tail -n 1 | fold -w 15 | tail -n 1

Basically we are cutting the line in half and selecting only the second half. This would be simpler with regular expressions but Id have to remind my self how to use all that again. Someone will prolly post with a easier solution.

Yes but you will need wget to be installed. (command line tool to pull in data over the web.)

this would give you a number of other useful features so I will look into it.

Point me to the site you would like the world clock info to come from and I will play tonight.

At some point I will look into writting my own widgets. But I think ill wait for the QT update in the UK. This way it will last through meego etc.

Ive tried the command for the date in the widget and i get an "invalid command" error on my widget.
