File renaming hardships

build · 2009-03-05 22:23:43

Hi there,

I have been trying to rename some files and it became a mess. I undone it, and now i could use some help please I am tired of trying things myself. And i am certainly not a hero when it comes to anything with programs.

I have a directory with 50 subdirectories, named like

"005 - lateral cosmonaut transportation vehicle"
"006 - trianguloid vacuum phaser"
etc.

In the directories are files which I want to rename in reversed order (last date stamped file will be renamed first). Files are currently typical digicam naming (e.g. P0000000.JPG). I would like to have the three numbers of the directory prefixed in the new filename. Then I want the new filename to have a "listnumber" Ill explain, thatll be more wise:

This is the current situation of a directory:

$ ls -x -1 --reverse
P1010857.JPG
P1010856.JPG
P1010564.JPG
P1010563.JPG
P1010562.JPG
P1010561.JPG
P1010560.JPG
P1010559.JPG
P1010558.JPG

That is reversed. Directory is lets say 041... Then i want the first file P1010857.JPG renamed to 041 - 001.jpg the second to 041 - 002.jpg.. etc etc.
For all 50 directory's contents
Help is appreciated!

Thanks

hmm, i like this project. here's what i'm thinking just off the top of my head:

#!/bin/bash

find ./ -maxdepth 1 -name '*' | while read dir; do
  count=1
  ls -x -1 --reverse $dir | while read file; do
    newname="${dir} - ${count}.jpg"
    mv ${dir}/${file} ${dir}/${newname}
    count=$(( count + 1 ))
  done
done

exit 0

someone who knows awk has to come along and get count to print as 001, 002, 003 etc. b/c i can't figure that part out.

IFS="
"
for dir in *; do ! [ -d "$dir" ] && continue; (i=1; cd "$dir"; for file in $(\ls -1 --reverse); do echo $file; mv --backup=t -v "$file" "$dir - $i.jpg"; i=$(($i + 1)); done; rename "- " "- 00" *-\ ?.jpg; rename "- " "- 0" *-\ ??.jpg) ; done

Well, that renaming is a bit of a hack. If you have +1000 pictures, then you will have to use
rename "- " "- 000" *-\ ?.jpg; rename "- " "- 00" *-\ ??.jpg; rename "- " "- 0" *-\ ???.jpg

For a simple-to-follow but not very efficient solution, you could implement the following pseudocode in your favorite language.

for each directory
    list all the files that end in .JPG
    sort the list in reverse order
    for each file in the list
        rename the file to "<directory> - <list index>.jpg"

I think mine is the first to do exactly what you asked for:

#!/bin/bash

dirname="`pwd | sed s,.*/,,`"

numplaces=`expr length $(ls | wc -l)`

i=0
ls -x -1 --reverse | while read fname
do
    i=$[i+1]

    iplaces=`expr length $i`
    fileext="`echo $fname | awk -F . '{print $NF}'`"

    newfname="$dirname - "
    echo $newfname
    echo $[numplaces-iplaces]

    j=0
    while [ $j -lt $[numplaces-iplaces] ]
    do
        j=$[j+1]
        newfname="${newfname}0"
        echo $newfname
    done
    newfname="$newfname$i.$fileext"
    echo $newfname

    mv "$fname" "$newfname"
done

Edit: Damn, I just realized you wanted this to be done for each directory. I'm too tired, though. It shouldn't be hard to add that bit yourself.

Thanks for the replies guys! However, none, of the scripts did the job. Ill describe what they did. I hope it wont sound as criticism bc i appreciate your efforts.

Executing Brisbin's script was followed by

mv: target '1.jpg' is not a directory
mv: target '1.jpg' is not a directory
...
ls: kan geen toegang krijgen tot ./010: Bestand of map bestaat niet
ls: kan geen toegang krijgen tot -: Bestand of map bestaat niet
ls: kan geen toegang krijgen tot nuclear: Bestand of map bestaat niet
ls: kan geen toegang krijgen tot assault: Bestand of map bestaat niet
ls: kan geen toegang krijgen tot hoover: Bestand of map bestaat niet

The ls:part says it cant access the directories, because file or directory doesnt exist. Each word or section of the filename or directoryname gets treated as if it were a file/dir.

btw: This happens also with plain ls (. e.g.: "for i in ls; do mv ...") Then stuff like permission, owner, group, date etc is included in the long print of errors. If anyone knows moving a filename can be treated as a whole, instead of the parts, then please tell. Although this is a bit off-topic, I never could have found an answer to this.

Procyon, your script does well. However, it does rename a file with the directory name in it. And something with zeroes when a dir has more than 10 files.

005 - 00lateral cosmonaut transportation vehicle - 8.jpg
005 - 00lateral cosmonaut transportation vehicle - 9.jpg
005 - 0lateral cosmonaut transportation vehicle - 10.jpg
005 - 0lateral cosmonaut transportation vehicle - 11.jpg

Some directories are just called 009 or 010. The content of those is renamed fine.

Killa B, your script, upon execution in a 0[0-9][0-9]* directory, does something strange. I cant get what it does. I tried it in different dirs with all other outcomes.

@build: I see, I missed that.

IFS="
"
for dir in *; do
! [ -d "$dir" ] && continue
(i=1; cd "$dir"
for file in $(\ls -1 --reverse *.jpg); do
mv --backup=t -v "$file" "${dir%% *} - $i.jpg"
i=$(($i + 1)); done
rename "- " "- 00" *-\ ?.jpg; rename "- " "- 0" *-\ ??.jpg)
done

I added a *.jpg check for files, and variable substitution ${dir%% *}

effing spaces... here's my new hack... works all except for 1.jpg instead of 001.jpg again; awk should do that but i don't know it:

EDIT: ok, got the awk command:

#!/bin/bash

find ./ -maxdepth 1 -name '*' | grep -v \./$ | cut -c 3- | while read dir; do
  count=1
  ls -x -1 --reverse "$dir" | while read file; do
    name=$(echo $count | awk '{printf "%03d", $1}')
    newname=$dir\ -\ $name.jpg
    mv "$dir/$file" "$dir/$newname"
    count=$(( count + 1 ))
  done
done

exit 0

and the result:

┌─[ 10:17 ][ ~/Temp/test ]
└─> lt
.
|-- 041
|   |-- 1234.jp
|   `-- 23456.jpg
`-- 051
    |-- 1234.jp
    `-- 23456.jpg

2 directories, 4 files
┌─[ 10:17 ][ ~/Temp/test ]
└─> photo_renamer
┌─[ 10:17 ][ ~/Temp/test ]
└─> lt
.
|-- 041
|   |-- 041 - 001.jpg
|   `-- 041 - 002.jpg
`-- 051
    |-- 051 - 001.jpg
    `-- 051 - 002.jpg

2 directories, 4 files

this should work with directories up to 999 files. change the awk command to increase this.

edit2: thanks toad, that's a good reference; google actually found me this which is just the printf syntax, which i knew awk accepts.

You want awk? Here is the only resource I have been able to make sense of so far...

That's weird, it works perfectly for me.
