I have analog camera and I give a film to the lab where they scan it, I wanted to upload it to flickr but want to change info about camera. Right now it's NORITSU KOKI QSS-32_33 and I wanted it to be pentax k1000 (I don't want to clear exif data). How can I do this from command line.

The tool you're looking for is called exiftool. You can use it to read & write exif meta data that's attached to a single image or a whole directories worth of files using its recursive switch (-r).
To change the camera model you can use the -model=".." switch.
Example
Here's an image before the change.
$ exiftool ff42403138dd5fa56e38efdaab2ced1435d0e28c.jpg

To change the model of my camera.
$ exiftool -model="sam's camera" ff42403138dd5fa56e38efdaab2ced1435d0e28c.jpg
Now when we recheck the tags.

There is another tool called exiv2 which does the same kinds of things as exiftool in case you're interested.
