shell script to make dirs and move files

I have a little program that generates different reports based on dates....and each file is tagged with a date and it stores the files in different directories.....

eg it generates these files...




and puts the files to corresponding directories....
eg all attendance records in a directory called attandance and student marks in a directory called student-marks...

you can assume that there will be any number of directories with different names....

I need a little shell script...that goes to each directory...and checks the date tag of each file....then creates a directory if it does not exist in the root level (ie top) directory...and moves the file with that date tag to the date directory....

in the example above we should get 3 date directories...




then in the directory
02-03-2000 we should move these file

in directory 03-04-2000 we should move

and in directory 04-05-2000 we should move

any ideas/suggestions....

I believe what follows will do what you want. Put it into a file and make that file executable. To use it cd to the directory containing the collections of directories which contain the files and execute the script on each directory.

# For the directory specified as the argument, look for file names like
# *-dd-dd-dddd*. For each such file found move that file to a directory
# named dd-dd-dddd at in the current directory (creating the dd-dd-dddd
# directory if needed).

if [ $# -ne 1 ]; then
  echo "Usage: $0 directory"
  exit 1
elif [ ! -d $1 ]; then
  echo "Usage: $0 directory"
  exit 1

cd $1

for file in *; do
  if [ -f $file ]; then
    DATE=`echo $file | sed -e "s/.*-\([0-9]\+-[0-9]\+-[0-9]\+\).*/\1/"`
    if [ ! -d ../$DATE ]; then
      mkdir ../$DATE
    mv $file ../$DATE

Thanks for your response...

But is there a way to make "cd" to each directory "automatic" it should automatically search all I don't want to "execute the script on each directory"....I want this process to be automatic as well.....

any suggestions....
Perl script might help.

$dir = "/your/root/dir"; # dir contains all the files

opendir DIR, $dir or die "Could not open dir - $dir:$!\n";
@a = grep !/^\.\.?$/, readdir DIR;
close DIR
foreach (@a) {
  if ($_ =~ /.*-(\d+-\d+-\d+)\.txt/) {
      $D{$1} .= " $_";
chdir $dir;
foreach $i (sort keys %D) {
    mkdir $i;
    foreach $j (split / /, $D{$i}) {
        next if (!$j);
        link   $j $i/$j;  # copy the file to dir $i
        unlink $j;     # remove file $j

Yes, but there'd need to be some way to recognize the directories that are to be considered as sources as opposed to those that are repositories of the collated data. In your question it sounds like there could be a number of them and the only thing that I could assume was that the would not have names of the form dd-dd-dddd. For instance if I know that all of the source directories would start with an alpha character, I could easily modify the script to process those. Or in a bourne/bash/ksh shell I could do:

for dir in [a-z]*; do do-dir $dir; done

I considered putting something like that in the script, but thought that it wasn't necessarily a valid assumption.
