Moving files from one directory to another based on 2 date variables

Hi All,

I am currently coding for a requirement(LINUX OS) where I am supposed to move a file (Lets Call it Employee.txt) from Directory A to Directory B based on 2 date fields as below,

Code:
Date_Current = 20120620
Date_Previous = 20120610

Source Directory : /iis_data/source
Target Directory : /iis_data/destination

Files available in Directory:
Code:
20120609_Employee.txt
20120612_Employee.txt
20120615_Employee.txt
20120616_Employee.txt
20120617_Employee.txt
20120620_Employee.txt

I need to move all these files (EXCEPT the 20120609_Employee.txt) to destination Folder.
Also, I need to write the above dates from the files to a dummy file.

Can you pls help me figure out how to do it ? Any help is appreciated.

Thanks Much
Freddie

The nice thing about YYYYMMDD dates is they sort and compare alphabetically.



Code:
#!/bin/sh

 Date_Current=20120620
Date_Previous=20120610

IFS="_"
for FILE in *.txt
do
        set -- $FILE

        if [ "$1" ">" "$Date_Previous" ] && [ "$1" "<" "$Date_Current" ] ||
                [ "$1" = "$Date_Previous" ] || [ "$1" = "$Date_Current" ]
        then
                echo mv "$FILE"
        fi
done

Thanks Corona for your reply.
This is what I am trying in my sample script,

Code:
 
Date_Current=20120620
Date_Previous=20120610
IFS="_"
for EMPLOYEE in /iis_data/source/*.txt
do
set -- $FILE
if [ "$1" ">" "$Date_Previous" ] && [ "$1" "<" "$Date_Current" ] ||
[ "$1" = "$Date_Previous" ] || [ "$1" = "$Date_Current" ]
then
echo mv "$FILE /iis_data/destination/"
fi
done

Can you pls let me know what I am doing wrong here.

That's not an error message. Smilie

Code:
for EMPLOYEE in '/iis_data/source/*.txt'

Did you put this in quotes in your original? It won't work if its in quotes.

Hi Corona,

Thanks for your reply. This is what I am seeing in the error log,

Code:
Date_Current=20120620
+ Date_Previous=20120610
+ IFS=_
/iis_data/source/20120609_EMPLOYEE.txt /iis_data/source/20120618_EMPLOYEE.txt /iis_data/source/20120619_EMPLOYEE.txt /iis_data/source/20120622_EMPLOYEE.txt /iis_data/source/CallParam.txt /iis_data/source/convertfuntionn.txt /iis_data/source/convert.txt /iis_data/source/Copybook.txt /iis_data/source/CPMGBUSDynamicDateFile1.txt /iis_data/source/CPMG_CDPH_Approach.txt /iis_data/source/CPMGDynamicDateFile_0410.txt

Looks like it read all the files that end with *.txt. Also, doesnt seem to move the files to the destination directory.
I suspect the below code part is causing the issue,

Code:
for EMPLOYEE in `/iis_data/source/*.txt`
do
set -- $FILE
if [ "$1" ">" "$Date_Previous" ] && [ "$1" "<" "$Date_Current" ] ||
[ "$1" = "$Date_Previous" ] || [ "$1" = "$Date_Current" ]
then
echo mv "$FILE /iis_data/destination/"
fi
done

Assuming that there is only one file per date, that the only dates in filenames in that directory occur in files of interest, and that there aren't other files whose names may sort within the date range, the following may be of use:

ls | sed -n "/$Date_Previous/,/$Date_Current/p; /$Date_Current/q" | xargs -I_ echo mv _ /iis_data/destination/

If the output is acceptable, remove the word "echo" to actually move files.

Alister

You did it again:
Code:
for EMPLOYEE in `/iis_data/source/*.txt`

That is in backticks and should not be.

In the code I actually posted, it was in no brackets, quotes, or ticks whatsoever. It is not supposed to be in any whatsoever. It will not work if you put it in any whatsoever.

Try the code I gave you without editing things that look funny. It is working code.
