Batch Files Rename sorted by date

I have folder/s I upload files to it/them, with 1000-20,000 files of deferent kinds (pdf, jpg, wmv...etc) with deferent file names and length with spaces in them ..etc
I am trying make Batch to rename them on a regular bases but I want them sorted by "oldest date first", and the new name will be in the format of YYYT000001.xxxx ... YYYY036242.xxxx (where YYYY is a fixed text "Jan" or Dec" (I will enter it manually in the script), and xxxx is the original file extensions)


I've tried to use the input "for i in $(ls- tr)" as it will be sorted by oldest date, and tried to replace the file names using "basename $i" ..etc.

I have searched the net but my thick head could not come up with a working script.


Any ideas / help

many thanks

hi. Instead of using the

Code:

---

for i in $(ls)

---

, have a try building your script with

Code:

---

find dirname -iname '*' | while read i ; do
your code
your code
your code
done

Many years ago, I tried some batch scripts like you with "for" or "cat" and couldn't get a positive result. As a gift, an example. This script sorts the files generated by my surveillance cameras and send them in different directories, by date :

Code:

---

#!/bin/bash
d=`date +%Y%m%d`
find /home/ftpusers/Incoming -iname '*.jpg' | while read a ; do
        b=`expr $a : "^.*_[0-9]_\(.\{8\}\).*"`
        c=`echo "/home/ftpusers/"$b`
        if [ $b -lt $d ]; then
                if [ -d $c ]; then
                        mv $a $c
                else
                        mkdir -p "$c"
                        mv $a $c
                fi
        fi
done

many thanks Captain, I will use your script as a guidance.

I get a help from "desert69" and post me the following script, but it can not handle spaces in the old file name, I can not figure out why, as all double quotes in place

#!/bin/bash
prefix="YYY"
i=0
for file in $(ls -tr)
do
filename=$(basename "$file")
extension="${filename##*.}"
paddedIndex=$(printf "%06d" $i)
mv $file ${prefix}${paddedIndex}.${extension}
i=$(($i + 1))
done

Hi

You may try this :

Code:

---

   
paddedIndex=$(printf "%06d" $i)
newfile=`echo ${prefix}${paddedIndex}.${extension}`
mv "$file" "$newfile"

---

many thanks for the help

I will try it and post back
