A bit optimized (without the useless
sed), parametric and verbose version:
Code:
test ~ $ cat img2iso.sh
#!/bin/bash
#VIDEO_ROOT_DIRECTORY="/Users/astrid/NFS/scripts/img2iso"
VIDEO_ROOT_DIRECTORY="/home/test/video"
IN_EXT=".img"
OUT_EXT=".iso"
for infile in $(find "$VIDEO_ROOT_DIRECTORY" -name "*${IN_EXT}" -type f)
do
echo "----------"
echo "Processing INFILE <$infile>"
n=0
exit=""
suffix=""
while [ ! "$exit" ]
do
newname="${infile%${IN_EXT}}${suffix}${OUT_EXT}"
if [ ! -f "$newname" ]
then
echo "NEW NAME OK! Renaming to <$newname>"
mv "$infile" "$newname"
exit="y"
else
echo "NEW NAME <$newname> already exists! Incrementing suffix"
n=$((n+1))
suffix="-$n"
fi
done
done
And the output before and after execution:
Code:
test ~ $ ls -lR /home/test/video
