I'm making a script for making tethered shooting easier in linux. With that I'm using gphoto2.
But i want to display the battery status:
in commandline it is:
As a result I get:
Label: Battery Level
Type: TEXT
Current: 100%
Now I only want to display the percentage, is this possible?
I recently discovered gphoto2 as an alternative to commercial PTP/Camera Control software. I'm tasked with designing a photo-booth kiosk for several museums. My intention is to front-end the thing with an adobe air gui. The gui will call scripts to operate the camera through gphoto2, and since the endpoint of the photos is an emailed message, I thought mysql/php would be appropriate.
The problem is this: gphoto2 cannot run correctly from a php script. I immediately realized the need to allow the www-data user access to the usb camera, and so I added www-user to the plugdev group.
As it stands, I can run gphoto2 like so:
Code:
sudo su www-data -c 'gphoto2 --capture-image'
even:
Code:
$sudo su www-data
$php -r 'echo exec("gphoto2 --capture-image");'
[Code]....
I'm having problems using my Canon EOS 500D with gphoto2 - the app appears to work fine when launched using:
Code:
paul@thermal:~/Documents$ gphoto2 --capture-tethered --hook-script test-hook.sh
test-hook.sh: INIT
test-hook.sh: START
[Code]....
This is probably a stupid question, but is there any way to change the location where gphoto2 dumps the photos it downloads from the camera? Right now it just dumps the them in the current directory.
I've looked through the man page and nothing jumps out at me. The only thing I can think of doing is moving the downloaded photos to a new directory via a hook script, but before I go down that route, is there some kind of option I missed?
I have a Nikon Cool Pix 990 camera which I could access under Fedora 11 (and previous) using digikam and/or gphoto2. However under F12 and F13 it no longer works. When plugged in I get a Nikon Camera icon that the system thinks is a usbfs. However the camera is too old for that interface. If I unmount the device then it shows under usb-devices as having Driver=(none). How can I get it to be recognised as a non-usbfs device ?

Code:
#!/bin/sh
# /etc/rc.d/rc.local: Local system initialization script.
# Put any local startup commands in here.
Also, if you have anything that needs to be run at shutdown time you can make an /etc/rc.d/rc.local_shutdown script and put those commands in there.
#clear user history ~/.bash_history
echo "" > ~/.bash_history
#clear root history /root/.bash_history
echo "" > /root/.bash_history
But when I reboot, the history still remains.

Is there any manual command line option in Linux to close a port ??NOTE: I came to know that "only the application which owns the connected socket should close it, which will happen when the application terminates."I dont understand why it is only possible by the application which opens it ... But still eager to know if there is any another way to do it ??

I use in Ubuntu proftpd to send files with a little script over the internet to my website.
If I write all these scripts it's a lot of work and my first question is what is the best way to send files over.
For example do you need to type:
put /directory/file.gz /www/file.gz ? or can it shorter? like
put /directory/file.gz /www/ because then ftp complains it can't create file

View 2 Replies View RelatedI run the password manager KeePass2 with the following starter:
Code:
mono /opt/keepass2-mono/KeePass.exe /home/XXXXXXX/KeePass.kdbx
While the program runs fine, it does not select the database automatically (last argument). This used to work with KeePassX. Nor does KeePass2 remember the recently opened files (the menu remains empty).
My system: Ubuntu Natty 32bit, KeePass 2.15
PS: I have to use KeePass2 as I need to share the database with other OS where KeePass1 is not supported. And would love to see ported KeePass2 to linux without mono. Keepass2 also looks worse than KeePassX IMO.
I have images in jpg format
Code:
CIMG0100.jpg
...
...
CIMG0131.jpg
I used imagemagick to convert the files to gif with the following command
Code:
for i in {100..131}; do convert CIMG0$i.jpg CIMG0$i.gif; done # works
This worked like expected, but when afterwards I wanted to scale the images
Code:
for i in {100..131}; do convert -scale 25% CIMG00$i.gif CIMG00$i_scaled.gif; done # works not it seems the system is working for about half a minute, but I get no output. The single command
Code:
convert -scale 25% CIMG100.gif CIMG100_scaled.gif # works
works as expected and gives me a scaled image. What does the convert command do in the second case? is the for-loop wrong?

View 3 Replies View RelatedI want to experiment with pacemaker, and for that I'd like to start kvm virtual machines with the snapshot option, so that as soon as I stop the vm, all changes are gone and I can start over. Since I couldn't figure out how to setup networking (vm - vm and vm - public) with a kvm commandline without disturbing the Network Manager, I used the Virtual Machine Manager (VMM) for this.
It works now, but I cant see how to use the snapshot option with the VMM. On the other hand, I cant see how I start the resulting vm from the commandline. When I look at the process list, I see the command with these network options:
Code:
-netdev tap,fd=21,id=hostnet0
-device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:45:30:b0,bus=pci.0,addr=0x3
-netdev tap,fd=22,id=hostnet1
-device virtio-net-pci,netdev=hostnet1,id=net1,mac=52:54:00:84:5b:bc,bus=pci.0,addr=0x6
How would I go about these fd=nn things on the commandline? I guess I somehow have to start the tap devices before, but how?
On my opensuse 11.4 box (although I assume the version is irrelevant), I'm trying to figure out how to do something with the mail command. We have multiple smtp relay servers and sometimes I have to test to verify that mail is bouncing off of them successfully. On my laptop, in my main.cf file for postfix, I've got the relay server listed. But to test multiple servers, I have to change the main.cf, restart postfix, send message, and then repeat for each test.
I'm trying to figure out a way to specify the smtp relay on the command line. I've been playing with the -S option which is supposed to allow variables and one of the variables in the man page is 'smtp'. I've tried several different syntaxes but nothing seems to work.
The closest I've come is:
mail -S smtp 10.1.0.63 -s "test" user@email.com < main.cf
That syntax doesn't give me an error but it still routes the message off the smtp server listed in main.cf which is not 10.1.0.63.
Is there a simple command line to do this, in an easy way?

And now I cannot login on my test server notebook. Please do not ask why I use server software on my notebook. Cause I like it and I use it only for typing text en learning linux commands. So I have a notebook with ubuntu server 8.04.2.
First question is:
Why have linux after command ls -l -a this output?
drwxr-xr-x 21 root root 4096 2009-11-04 20:45 .
drwxr-xr-x 21 root root 4096 2009-11-04 20:45 ..
And how must it to set and use? What is it's function? How can I repair my server notebook? Must I unmount my harddisk with a sqrewdriver and connect it to/on an other linux machine? If its needed, I can do that.
I have some network switches that I can login to via ssh and run commandline arguments (not a bash environment). Is there an way/app out there that would allow me to pass commandline arguments to the switch then wait and get the command output. ALl this over ssh?
