Batch Script to rename files...

boerl · 12-25-2008, 02:08 PM

i wrote an extension which also can renumber files. in case someone is interested:

Code:

#!/bin/bash
#regexp rename utility with renumbering of groups of files
#files with the same portion anywhere in the filename can be numbered anywhere in the filename  
#in dsl linux shell
#note:
#this script deletes file called groups.txt if present

dir="/mnt/hda5/ps fotos"

echo >groups.txt
i=0
ls "$dir" | while read file; do
   echo old $file
   group=`echo $file | sed -e "s/^\(....\).*/\\1/"`
   found=`sed -n "-e /$group/ {p q}" groups.txt`
   if test -z "$found"
   then echo "$group" >> groups.txt
     i=11                                           #starting value
   else
     i=`expr "$i" + 1`                              #increment
   fi
   prettyi=`printf "%03d" "$i"`                     #%03d is 000 to 999 to 1000..
   newname=`echo $file | sed -e "s/^\(....\) ....../\\1 ""$prettyi""000/"`
   echo new $newname
   mv "$dir/$file" "$dir/$newname"
done
rm groups.txt

#renames files like
# 1989 112200 corio.jpg
# 1989 112201 corio.jpg
# 1990 112300 corio.jpg
#to
# 1989 011000 corio.jpg
# 1989 012000 corio.jpg
# 1990 011000 corio.jpg
#that is, renumbers files starting with 11000 each new year. increment is 1000.
#order doesn't change

#remember chmod +x foo.sh

#thx to jamiew  for Handling filenames with spaces in a bash for loop
#thx  Bebo from Go"teborg for the  Batch Script to rename files...

Thanks for these! Here's my version.

For images.

This code will just rename all files in given folder to 0,1,2,3,4 .jpg

WARNING, usage:

/path/to/batchrename /PATH/TO/FILES/

Code:

#!/bin/bash
#regexp rename utility with renumbering of groups of files
#files with the same portion anywhere in the filename can be numbered anywhere in the filename
#in dsl linux shell


dir=$1


i=0
ls "$dir" | while read file; do
   echo old $file
   newname=`echo "$i.jpg"`
   let "i=$i+1"
   echo new $newname
   mv "$dir/$file" "$dir/$newname"
   echo "------------------------------------"
done
