Shell Programming and Scripting

Hi All,

I have thefollowing files in the directory inbox/sat

ras.sat.trn.20090103.001902.00004358
ras.sat.trn.20090612.001903.00005339
ras.sat.trn.20090723.001902.00004358

The above file contains the date of the file creation. We just need to write a ksh shell script to check the filedate against currentdate.If the file is less than 200 days old(from the current date),then we don't want to open/process the file, all we need is to move it to the different directory.

Can you kindly give me some ideas on how to achieve the solution.

thanks,

Are these files modified after their creation or just created and left alone to be processed/moved later?

Try this:

Code:

ls -1 inbox/sat/ras.sat.trn.* > files.txt

Code:

todate=$(date -d "100 day ago" +%Y%m%d)
while read str ; do
filedate=$(echo $str | cut -d. -f4)
if [[ $filedate < $todate ]] ; then
 echo "Dont move"  # for testing only
else
 echo "Move it"    # mv $str newdir
fi
done < files.txt        # inbox/sat/files.txt

Hi,

The files are just created and left alone.



Thanks,

Hi,

When i try this it shows me an error


$ date -d "100 day ago" +%Y%m%d
date: illegal option -- d
Usage: date [-u] [+format]
date [-u] [mmddhhmm[[cc]yy]]
date [-a [-]sss.fff]



Thanks,

How about:

Code:

find /your/directory -mtime +200 -exec mv {} /wherever/you/want \;

+200 for greater than and -200 for less than.

1. The files are just created and left alone.
--- That is because I am just echoing and not moving.
--- You will have to change that line to your requirement.

2. When i try this it shows me an error
--- Seems like you have version issues.
--- -d is not an option.
--- Type the following at the prompt and tell me what happens:

Code:

ksh
date -d "100 day ago" +%Y%m%d

Also, try

Code:

date --h
