Batch rename

[reminett]

Hi!

I have tried searching for any solution without any luck.

I have about 11 000 jpg images that is named like this:

image-240211-132301.jpg (24. february 2011, at 01:23:01 PM)
image-250211-142301.jpg (25. february 2011, at 02:23:01 PM)

All of these files have correct file system created/modified date (meaning its the same as my timestamp in the file names).

How do I rename all the files like this:

image000001.jpg
image000002.jpg
image000003.jpg

...sorted by date?


I would very much appreciate any help.

hmmm found no easy way to do this.

Maybe this will help you:
#####################
#/bin/bash
value=0001
for i in `ls /directory/*.jpg -tr`; do ##you can add R to make it recursive, of course
if [ $value -lt 10 ]; then
new_value=00000$value
elif [ $value -lt 100 ]; then
new_value=0000$value
elif [ $value -lt 1000 ]; then
new_value=000$value
elif [ $value -lt 10000 ]; then
new_value=00$value
elif [ $value -lt 100000 ]; then
new_value=0$value
else
new_value=$value;
fi
mv $i image$new_value.jpg
value=$(($value+1))
done

Hi.

This script generates commands to rename the files:

#!/usr/bin/env bash

# @(#) s1	Demonstrate rename of inconveniently-named files.

# Utility functions: print-as-echo, print-line-with-visual-space.
pe() { for i;do printf "%s" "$i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
# Context with local commands.
[[ -f ~/bin/context ]] && . context sed paste sort seq date

FILE=${1-data1}

pl " Sample data file $FILE:"
cat $FILE

pl " Strings denoting seconds since 1970:"
# Remove some bad characters from date string,
# remove string "at" from date,
# remove all data *except* the date string,
# feed into GNU date to get time since epoch (1970)
pe
sed -e 's/[.,]//g' -e 's/at//' $FILE |
tee t1 |
sed -e 's/^.* (//' -e 's/)//' |
tee t2 |
date +'%s' --file - |
tee t3 

pl " Epoch time pasted in front of file names:"
# put the time since epoch to front of file name,
# sort numerically.
pe
paste t3 $FILE |
sort -k1,1n |
tee t4

pl " Move commands, to be saved and executed later:"
# extract the original file name, now in order by date,
# adding a "move" command string at the front,
# create a file of new names as in requirements,
# write a series of move commands, to be executed later after
# correctness for situation has been verified.
pe
# to files named like " image000001.jpg"
cut -f2 t4| sed -e 's/^/"/' -e 's/$/"/' -e 's/^/mv /' > t5
n=$( wc -l < t5 )
printf "image%06d.jpg\n" $( seq 1 $n ) > t6
paste -d" " t5 t6

It's possible that the mtime of the files could be used to make things easier -- say with command stat, but I didn't / don't have those files ... cheers, drl
