Lazy Guide to gphoto2

As I told you in
http://cacianqalbukunderemp.blogspot.com/2008/09/pengalaman-mengambil-file-dari-canon.html


gphoto2 had successfully get pictures from PTP cameras to my Kuliax Linux. And as I told you before, I used manual from page http://gphoto.sourceforge.net/doc/manual/using-gphoto2.html.

Other neat gphoto2 are

1. -p RANGE or --get-file RANGE
What is RANGE?
Well, when you execute command "-L" or "--list-files" you'll see all files in your camera are enumerated started from one regardless the directory they were located. For example, the files in my wife's Canon Powershot SD750 are shown as the following

There is no file in folder '/'.
There is no file in folder '/store_00010001'.
There is no file in folder '/store_00010001/DCIM'.
There is no file in folder '/store_00010001/DCIM/100CANON'.
There are 6 files in folder '/store_00010001/DCIM/101CANON'.

There is no file in folder '/store_00010001/MISC'.


Hence, the RANGE is the number between 1 to 61. RANGE can be represented as comma-separated. For example "1-5, 7" means the files you were selected were "1,2,3,4,5,7". RANGE was also XOR (exclusive OR), hence "1-5,3" means "1,2,4,5" (and '3' is excluded).



2. --shell
I encountered problem while deleting a file. I wasn't sure what happened but the command "--delete-file RANGE" didn't work. It said:
*** Error ***
There are no files in folder '/'.
*** Error (-2: 'Bad parameters') ***
As I said above, the RANGE should actually disregards the folders. Sigh..

Fortunately, it had "--shell". I can traverse directory using command "cd" like usual and "delete" the file using filename.




Of course,
the best documentation is man page.
Just type "man gphoto2" for the best usage documentation.
