Comment faire quand j’ai deux cartes mémoires l’une après l’autre dans mon appareil photo et que je veux des noms de fichiers qui se suivent ?

# There has to be at least one file in the current folder responding to the given pattern
# start of variables
prefix=DSC_ # file name prefix
extension=NEF # file name suffix
digits=4 # number of digits
increase=257 # will be added to index
# end of variables
lengthofprefix=${#prefix}
files=($prefix*.$extension)
# Rename files in reverse order to avoid collisions
for ((i=${#files[@]}-1; i>=0; i--))
do
file=${files[$i]} # DSC_0047.JPG
index=${file:lengthofprefix:digits}; # 0047
index=`echo $index|sed 's/^0*//'`; # 47 - so that not interpreted as hex
newindex=$((index+increase)); # 333
newindex=`printf "%0${digits}d" $newindex`; # 0333
newfile=$prefix$newindex.$extension; # DSC_0333.JPG
echo renaming $file to $newfile; # renaming DSC_0047.JPG to DSC_0333.JPG
mv -i $file $newfile
done
