UNIX for Dummies Questions & Answers

Hello, everyone! :]

I'm having an issue with my camera/uploading to Photobucket.

When my camera transfers it's photos to my hard drive, it transfers them as .JPG. Unfortunately, when I go to upload to my Photobucket account, it only accepts .jpg & .jpeg files. Every time I want to upload, I have to go through the swath and rename them as .jpg files. This is terribly inconvenient and time consuming, and I was wondering if anyone has heard of a program, or has a terminal command that would change them automatically.

Alternatively, if someone knows how to add .JPG to my list of used picture formats alongside .jpg & .jpeg, that would be just as usefull, if not more usefull.

Note: I run Ubuntu 8.04 and I don't use F-spot, as that program is garbage.

Thanks in advance! - Spidydude

from the command line, run this one-liner in the same directory as the .JPG files:

Code:

for i in *.JPG ; do NAME=${i%%.*}; mv $i $NAME.jpg ; done

andrew@andrew-desktop:~/Desktop$ for i in *.JPG ; do NAME=${i%%.*}; mv $i $NAME.jpg ; done
mv: target `snowflake.jpg' is not a directory
mv: target `F40.jpg' is not a directory
mv: target `black.jpg' is not a directory

Since you're on Linux, this could work

Code:

rename .JPG .jpg *.JPG

Note that the rename utility isn't available on (most) other UNIXes, I have only seen it on Linux thus far.

andrew@andrew-desktop:~/Desktop$ rename .JPG .jpg *.JPG
syntax error at (eval 1) line 1, near "."


Sorry for the n00bishness, you guys. Still trying to learn more about the command line.

Post the output of

Code:

$ file `which rename`
$ file /usr/bin/prename

The problem is that the usage of the rename utility isn't stable, and can even differ between distributions released at the (roughly) same time.

for i in *.JPG; do mv ${i} `echo ${i} | sed 's/JPG/jpg/'`; done
