Batch processing pictures on the command line
If you have a lot of holiday pictures to process, the command line interface may provide exactly what you need:
- To rename all pictures according to the date they were taken (based on the EXIF information contained therein):
$ for i in *.jpg; do jhead -n%b-%d-%G_%R:%S $i; done
- To scale all pictures by a factor of 0.25, invoke
$ for i in *; do convert -scale 25%x25% $i `echo $i | sed -e 's/.jpg//g'`_sm.jpg; done
- To rename all the small pictures in such a way that the "_sm" suffix disappears, use
$ for i in *; do mv $i "`echo $i | sed -e 's/_sm.jpg//g'`.jpg"; done
We assumed that jhead
are present on your Linux system.
The tables with holiday pictures
on my home page
have been generated on these processed images using the webgallery
program This relatively simple program does a wonderful job.
