 Posted: Thu May 05, 2005 6:44 pm Post subject: automatic aterm command execution wit |
 |
|
Hello,
in order to retrieve my printer's current ink level I'll have to type | Code: | | sudo escputil --ink-level --new --raw-device /dev/usb/lp0 |
, which is quite a lot, indeed. To make things a bit more comfortable I created a menu entry that opens an aterm, which then executes the above mentioned command. | Code: | | aterm -e sudo escputil --ink-level --new --raw-device /dev/usb/lp0 |
This does work fairly well, except for it closes the aterm when escputil's finished so I can't read the actual information!
Any hints

This is a way you can try.
Create a script file "inklevel.sh"
| Code: |
#!/bin/bash
#~/inklevel.sh
sudo escputil --ink-level --new --raw-device /dev/usb/lp0
sleep 10
|
Then
| Code: | | chmod +x inklevel.sh |
Then
| Code: | | aterm -e ~/inklevel.sh |

A bit more elaborate is this:
| Code: | #!/bin/bash
#
INKLEVEL=$(sudo escputil --ink-level --new --raw-device /dev/usb/lp0)
zenity --info --text=$INKLEVEL |
You need to emerge zenity for this to work, but then everytime you call this script from the menu a gtk dialog will pop up reporting back the output of your inklevel program, and it stays until you click OK. Ain't that better than a crummy aterm?

kamagurka,
nice idea, but in the end, it didn't work out very well, since the two " sorrounding the brackets are necessary in this case:
| Code: | #!/bin/bash
# this the retrieve ink level script by mmb (use and distribute under the GPL)
tmpfile=/tmp/inklevel.$$
sudo escputil --ink-level --new --raw-device /dev/usb/lp0 >> $tmpfile
zenity --info --title="Ink levels" --text="$(sudo escputil --ink-level --new --raw-device /dev/usb/lp0)"
rm -f $tmpfile |
Hope, this helps.

What is that tmpfile doing in there?

Yup, it's not necessary. I could have equally well replaced it with the sudo command, but I found it a bit cleaner in this script to divide it into two different lines[/code]: | Code: | #!/bin/bash
# This the retrieve ink level script by MMB (use and distribute under the GPL), thanks to kamagurka from Gentoo forums
tmpfile=/tmp/inklevel.$$
# sudo escputil --ink-level --new --raw-device /dev/lp0 >> $tmpfile
# if you have a parallel port printer, please uncomment the line above (L6) and comment out the next (L8)
sudo escputil --ink-level --new --raw-device /dev/usb/lp0 >> $tmpfile
zenity --info --title="Ink levels" --text="$(cat $tmpfile)"
rm -f $tmpfile |
