Need help with shell script - renaming multiple files

whansard · 06-02-2004, 10:45 PM

rename "2.dd-" "" *
rename "-dead-" "" *
for i in 0 1 2 3 4 5 6 7 8 9 ;do rename .gif$i .gif *;done

run that last one 5 times, then change the .gif's to .jpg's.

whansard · 06-02-2004, 11:08 PM

i didn't realize that > was part of the filename.
after all that above.
rename ".gif>" ".gif" *

This is most likely where I messed up. I'll re-try and report back.

Thanks for sticking with me on this one Dark Helmet!! you are a god-send.

whansard - I'll give yours a bash too...and see where it leads!thanks

i created the files you put in your first post and did what i had to to get it the way you wanted.

/test# ls

then a few more things to take care of the .jpg files

i guess as a script it could be

rename "2.dd-" "" *
rename "-dead-" "" *
for j in 1 2 3 4 5 ; do
for i in 0 1 2 3 4 5 6 7 8 9 ;do rename .gif$i .gif *; rename .jpg$i .jpg *;done
done
rename ".jpg>" ".jpg" *
rename ".gif>" ".gif" *

For good measure, I thought I'd throw this one in too. It's a perl script, but it still requires the find command format earlier.

Code:

#!/usr/bin/perl

if ($#ARGV > -1 )
{
  $filename = shift;
  $new_filename = $filename;

  if ( $new_filename =~ /\.dd-/ )
  {
    $new_filename =~ s/\.dd-//g;
  }

  if ( $new_filename =~ /-dead-[0-9]*>/ )
  {
    $new_filename =~ s/-dead-[0-9]*>//g;
  }

  if( $filename ne $new_filename )
  {
    system mv, $filename, $new_filename;
  }
}

It will rename the file in one action. It'll take care of the ".dd-" and "-dead-" portions. Create the script (I named it file_rename.pl), make it executable, and then (assuming it's in the same dir as the files to rename) type this at your bash prompt (you're creating a mini-wrapper script):

Code:

 ls | while read filename; do ./file_rename.pl $filename; done

Please, help!
I have a problem: plenty of Japanese files, with disguised names, such as: V^[N[X܂̓X@�5 .doc (invalid Unicode)
In some instances they have no extention, or the period before:
V^[N[X܂̓X@�5?doc
The lenght of the names is always different.
All these files were imported from Windzoo 97.

OpenOffice opens them beautifully (btw, the latest OpenOffice works like charm, and loads really fast! I also solved the problem of printing margins.), if the names look like something more civilized, say, 1.doc, 2.doc etc.

I need a script wich will batch rename all these files, replacing the names with a number and *.doc extention.
I read mv and rename man, but this task is beyond my skills.

Can anyone post here a ready to use script, or something I could start with? Thanks in advance.

P.S. rename ".doc (invalid Unicode)" ".doc" *
works, but I don't know what to do with the mess before the extension

Dark_Helmet · 07-03-2004, 05:24 PM

Here's a basic script:

Code:

#!/bin/bash

document_number=1

old_ifs=${IFS}
IFS=$'\n'

for filename in $( ls -1 *.doc ) ; do
  mv -v "${filename}" ${document_number}.doc
  ((document_number=document_number+1))
done

IFS=${old_ifs}

exit 0

Save it, and then make it executable (chmod u+x filename)

Cd to the directory with the documents to be renamed, and execute the script.

As I mentioned earlier, always try new scripts that move or delete files on a test set of data first. Verify that it does what you want it to do before running it on your originals.

linuxfond · 07-03-2004, 06:26 PM

This looks nice. It should work and I will give it a try now.
BTW, Today while I was messing up with these scripts, I renamed all folders in the /root directory (incidentally I run the script as root -- luckily I have not donemore damage!)
Anyway, all folders in /root were renamed in 1.doc 2.doc 3.doc
I figured out that one of them was tmp folder, another was Desktop, the third folder contains log files, auto-install.pl script etc. I don't remember what was the name of this folder. Do you have any idea?

linuxfond · 07-03-2004, 06:34 PM

bash-2.05b$ ./rename
`}}*&||':#$%^(&^.doc -> `number.doc'
`%^(&^.doc.doc' -> `number.doc'
`%^(&^^&^.doc.doc' -> `number.doc'
`%^^.doc.doc' -> `number.doc'
`Japan##$%(*&.doc' -> `number.doc'
bash-2.05b$

Unfortunately, it replaces all the files with one just file: number.doc
Something is missing...

Dark_Helmet · 07-03-2004, 06:41 PM

There was a typo in the script. Change this line:

Code:

  mv -v "${filename}" ${document-number}.doc

To this:

Code:

  mv -v "${filename}" ${document_number}.doc

As for the problem with renaming the directories in root, well, it all depends on your installation. There are some standard ones:
/bin
/boot
/dev
/sbin
/home
/usr
/tmp
/var
/etc
/lib
/opt
/proc
/root
/mnt

The one that contains log files is typically /var.

linuxfond · 07-04-2004, 10:45 AM

Thanks! I figured out that the 2.doc was originally drakx.
That's what we have in MDK.

I will try the script now....

THANKS indeed! It works beautifully.
