Hi!
I wanted to share a script I wrote originally to insert a forgotten photo into a sequencial image set (01image1.jpg, 02image2.jpg, ...).
If index is already used, it shifts all later files in the sequence, and then introduces the new file.
Code:
# Script to insert a filename into a sequenced file set.
# It updates numerotation if given number already present into the sequence.
# Usage: insertphoto.sh [distdir] [-nXX] filetomove filename
# will move filetomove to [distdir/]XXfilename.ext (ext is extracted from given filetomove)
if [ -d "$1" ];
then
distdir="$1";
shift
else
distdir=`pwd`;
fi
IFS=$'\n'
insno=00;
while [ -n "$1" ]; do
if [[ "$1" =~ -n[0-9]+ ]];
then
insno=`printf "%02d" ${1:2}`;
else
if [ -f "$1" ];
then
filetomove="$1";
basetomove=`basename "$filetomove"`;
doexist=`ls -1 "$distdir/$insno"* 2>/dev/null`;
# renumerate if number already in sequence
if [ -n "$doexist" ];
then
for i in $(ls -1 "$distdir/"[0-9]* 2>/dev/null); do
filename=`basename "$i"`
numi=`expr "$filename" : "\([0-9][0-9]*\)"`;
if [[ "$numi" -ge "$insno" && "$filename" != "$basetomove" ]];
then
((numi+=1));
numi=`printf %02d $numi`;
mv "$i" "$distdir/$numi${filename:2}";
fi
done
fi
# no given number: look for biggest, and increment it
if [ $insno -eq 0 ];
then
lsarr=($(ls -1 "$distdir/"[0-9]* 2>/dev/null));
lenarr=${#lsarr[*]};
if [ "$lenarr" -ne "0" ];
then
((lenarr-=1));
lastfile="${lsarr[lenarr]}";
insno=`expr "$lastfile" : "\([0-9][0-9]*\)"`;
((insno+=1));
insno=`printf "%02d" $insno`;
else
shift;
break;
fi
fi
shift;
# inserting file
mv "$filetomove" "$distdir/$insno$1.${basetomove##*.}";
fi
fi
shift;
done
It is maybe useful to somebody...
Take care!
