 Posted: Wed May 14, 2008 7:39 pm Post subject: Bash recursive file rename [for Linux nerds] |
 |
|
I just passed the 10.000th picture and my Samsung has reset his counter ... which means that the next file to sg1s9999 is ... sg1s0001.
I decided to rename old files with 6 digits (allowing 999999 pictures, yes, I know, I'm a bit too enthusiastic), renaming sg1s0001 to jf010001 and, while at it, extracting jpeg preview from raw files.
Here is my bash script (largely inspired by another script found on the Net) :
| Code: |
#!/bin/sh
rename_recursive()
{
for file in "$1"/*; do
if [ -d "$file" ]; then
rename_recursive "$file"
else
dirname=`dirname "$file"`
basename=`basename "$file"`
singlename=${basename%.*}
beg_name=${basename:0:4}
extension=${basename##*.}
# If file begins in sg1s, meaning a Samsung GX1s file
if [[ "$beg_name" == "sg1s" ]]; then
# If file ends in JPG
if [[ "$extension" == "jpg" ]]; then
newfile="$dirname/jf01${singlename:4:10}.jpg"
if [[ "$file" != "$newfile" && ! -f "$newfile" ]]; then
echo "Renaming '$file' to '$newfile'..."
mv "$file" "$newfile"
fi
fi
# If file ends in PEF (Raw Pentax file)
if [[ "$extension" == "pef" ]]; then
newfile="$dirname/jf01${singlename:4:10}.pef"
if [[ "$file" != "$newfile" && ! -f "$newfile" ]]; then
echo "Renaming '$file' to '$newfile'..."
mv "$file" "$newfile"
fi
/usr/local/sbin/dcraw -e -h -v -a $newfile
fi
# If file ends in XCF (if I saved a raw with layers)
if [[ "$extension" == "xcf" ]]; then
newfile="$dirname/jf01${singlename:4:10}.xcf"
if [[ "$file" != "$newfile" && ! -f "$newfile" ]]; then
echo "Renaming '$file' to '$newfile'..."
mv "$file" "$newfile"
fi
fi
# If file ends in PNG (you never know :) )
if [[ "$extension" == "png" ]]; then
newfile="$dirname/jf01${singlename:4:10}.png"
if [[ "$file" != "$newfile" && ! -f "$newfile" ]]; then
echo "Renaming '$file' to '$newfile'..."
mv "$file" "$newfile"
fi
fi
fi
fi
done
}
for dir in $@; do
dirpath="$PWD/$dir"
if [ -d "$dirpath" ]; then
echo "Dir: $dirpath"
rename_recursive "$dirpath"
fi
done

It could be more elegant but it does the trick.

As a fellow LInux nerd (I collect distributions like I collect MF lenses) Thanks!

I'm a slackware fan for years (just switched to Zenwalk, but hey, it's still slackware-ish). I managed to get rid of Windows No more dual-boot since years !
