who's good at the terminal? need to move a bunch of files into directories - mattkime - 12-04-2009

i have thousands of images named by the time they were taken and i need to move them into directories to make them more manageable.

for instance, all files named starting with 91108 need to go into 2009-11/08/

i know mv is the command, i know * is the wildcard, but i don't know how to put it all together.

do you?

thx!

How about output redirection.

For example, you can redirect the output of the "ls" command from the monitor to a file that you create on the fly like so:

ls > filename

Can this also be used to create directories on the fly?

Assuming you are in the directory where all the photo files reside, and that you want to add directories in the same directory:

$ mkdir -p 2009-11/08
$ mv 91108* 2009-11/08

will create the new directory (actually a new directory 2009-11 and a subdirectory 08 within that) and move all files beginning 91108 into the new (sub)directory.

I'll have to think a bit about processing all of 2009 ...

Here's a bash shell script that should do what you want.
copy the lines inside (not including) the ==snipsnip== into a file
called, say foo.sh
=========snipsnip=================

#!/bin/bash

#

debug=1         # set debug to 0 to run for real

if (( $debug )) ; then 

    ECHO=echo

else

    ECHO=

fi

#

hath=( 00 31 28 31 30 31 30 31 31 30 31 30 31 )

for (( m=1 ; m <= 12 ; ++m )) ; do

    if (( $m < 10 )) ; then

        mm=0$m
    else

        mm=$m

    fi

    for (( d=1 ; d <= hath[m] ; ++d )) ; do

        if (( $d < 10 )) ; then

            dd=0$d
        else

            dd=$d

        fi

        nd=2009-$mm/$dd
        $ECHO mkdir -p $nd

        $ECHO mv -f 9${mm}${dd}* $nd

    done

done

echo All done.

#

=========snipsnip================

make foo.sh executable:

$ chmod +x foo.sh

and put it in the directory where the photos reside, and where the
new month directories (and their respective day subdirectories) will be.

$ ./foo.sh

will run the new script.

The script is set to only echo the commands it would do to create each directory and move files to it. (debug=1 at the beginning).

To make it run for real, edit the script and change debug=1 to debug=0
and run the script. Directories will be created and files moved.

Test it first. Make a directory with copies of a few photo files of different dates.
(or you can just sit in the new empty test directory 'touch' some file names to create empty files to be moved).
