Who can finish this script?
Good morning dear friends,

I want to write an UNIX script to do the following task:

We have 6 directories, called (SMS_01, SMS_02 ....... SMS_06), some files are distributed across these directories, but the distribution process is not good, I mean when I check these directories I found the following result:

Code:
drwxr-xr-x 3 root system 1495040 Sep 09 08:06 SMS_01
drwxr-xr-x 2 root system 256       Sep 09 15:48 SMS_02
drwxr-xr-x 2 root system 256       Sep 09 15:42 SMS_03
drwxr-xr-x 2 root system 256       Sep 09 15:45 SMS_04
drwxr-xr-x 2 root system 256       Sep 09 15:37 SMS_05
drwxr-xr-x 2 root system 256       Sep 09 15:55 SMS_06

All what I want is the distribution process done equally across these 6 directories, so each one receive 100 files for example.

Waiting your ideas.
Many thanks

What is the source of the files? If you control that you could maintain a counter within it and send the next file to printf "SMS_0%d", (file_count % 6) + 1

otherwise you'd have to "post process" by, for example, running find to geta count of files only within the directory structure and then running find and sending the first 1/6th of files to sms_01 etc...

but we're unlikely to finish work you haven't started (or indeed fully specified)

Hello Skrynesaver
Thanks for your suggestions.
I started many times and write some lines but I can't get the idea, I don't know how to distribute the files equally.

Anyway, the files generated from other servers, these files are transferring automatically through ftp to the these directories.

I have an idea but I can't translate it into shell script, the idea is: after receiving the files, suppose directory number 1 received 210 files, and directory number 2 didn't receive any thing, and directory number 3 received 117 files, and directory # 5 received 80 files, and directory # 6 didn't receive.

So, at this point, how can I redistribute the whole files equally, so every directory has the some number of files?!

Code:
#!/usr/bin/ksh
TOTAL_NR_OF_FILES=$(find SMS_* -type f | wc -l)
AVG=$(expr $TOTAL_NR_OF_FILES / 6)

SUFFIX=1
MOVED=0
for FILENAME in $(find SMS_* -type f)
do
 if [ $MOVED -eq $AVG ]
 then
   SUFFIX=$(expr $SUFFIX + 1)
   MOVED=0
 fi
 echo mv $FILENAME SMS_0${SUFFIX}/$(basename $FILENAME) 2>/dev/null
 MOVED=$(expr $MOVED + 1)
done

You may remove the red echo after verifying the output.

Note: The script has to be executed from the directory where all the SMS* directories are available.

Dear krishmaths,
The script seems good, I will try it now in testbed server then I will tell you the result.
Thank you very much.

A good start, but IMHO not correct. One must consider source directories above average and target directories below average...

Hello my friend,

I created 6 directories (MMU_01, MMU_02 .... MMU_06) and I distributed 24 files between them (not equally) then I applied this script (after changing the name of directories from SMS_* into MMU_*)

But nothing moved between directories, i.e. the empty directories still empty, and the directory which have 11 files still have the same number.

I think there is something missing in the script.

Please check the out put with me as the following:

Here is the 6 directories + the script file:
Code:
[P550_APP4][root]/Scripts/test> ls -l
drwxr-xr-x    2 root     system         4096 Sep 10 10:04 MMU_01
drwxr-xr-x    2 root     system          256 Sep 10 09:54 MMU_02
drwxr-xr-x    2 root     system          256 Sep 10 09:56 MMU_03
drwxr-xr-x    2 root     system          256 Sep 10 09:56 MMU_04
drwxr-xr-x    2 root     system          256 Sep 10 10:01 MMU_05
drwxr-xr-x    2 root     system          256 Sep 10 09:54 MMU_06
-rwxr-xr--    1 root     system          331 Sep 10 10:06 test.sh

After applying the script, this result appearing:

Code:
[P550_APP4][root]/Scripts/test> ./test.sh
mv MMU_01/dwe.txt MMU_01/dwe.txt
mv MMU_01/dwedwe.txt MMU_01/dwedwe.txt

mv MMU_05/ghgydf.txt MMU_06/ghgydf.txt
mv MMU_05/ghgy.txt MMU_06/ghgy.txt

Then I checked the first directory to make sure, but it still have 11 files!

Code:
[P550_APP4][root]/Scripts/test> cd MMU_01
[P550_APP4][root]/Scripts/test/MMU_01> ls -l

Yes it is good script, I learned some concepts from Mr. krishmaths.
I appreciate your notes, kindly refer to the previous reply to see the result, and apply your notes into script to fix the problems, because it needs some correction.

Thanks a lot MadeInGermany Smilie
