Hep with script to monitor directory

cmf00186 · #1 (**permalink**) 10-24-2006

Hello,

I am a newbie who is attempting to write a script to monitor a directory for a set of 3 files that I am expecting to get ftp’d. Occasionally, we suspend operations for maintenance etc. but we still get the files so there can be more than 1 set. If there is more than 1 set, I would like to move all but the latest set to an archive directory.

For example say the files are named:
acme1_090106.txt
acme1_091006.txt
acme1_092206.txt
acme2_090106.txt
acme2_091006.txt
acme2_092206.txt
acme3_090106.txt
acme3_091006.txt
acme3_092206.txt

I would like to move the older files to an archive directory
acme1_090106.txt
acme1_091006.txt
acme2_090106.txt
acme2_091006.txt
acme3_090106.txt
acme3_091006.txt

I am running AIX version 5.31.

This is what I have so far. Any suggestions would be deeply appreciated.

#!/bin/ksh
#
files=0
LoopCnt=0
while (( $files < 4 )); do
echo `date`
for name in `ls acme*`; do
if [ -f $name ]
then let files=files+1
fi
done
if (( $files < 3 )); then
if ((LoopCnt < 6)); then
echo "do not have 3 files yet, sleeping 10 minutes"
echo ""
sleep 600
files=0
let LoopCnt=LoopCnt+1
else
exit
fi
fi
done
This is where I'm stuck

if (( $files > 3)); then
echo "Have more than 3 files, move all but the latest to archive”
exit
fi

There are many ways in doing it... one is based on the time the file created in the system and the other way is based on date in the file name...

There will be a problem with the first method if the latest file ftp'd before the old files... old files will have latest file creation date than latest files and will move latest files to the archive folder...

Hence I adopted the second method which archives the file based on the date in the file name... hope this helps.

Code:

#!/usr/bin/ksh

for name in $(ls acme* | sed 's/_[0-9]*.txt//g' | uniq)
do
   cnt=0
   for fname in $(ls $name* | sed 's/_\([0-9][0-9]\)\([0-9][0-9]\)\([0-9][0-9]\)/_\3\1\2/g' | sort -r )
   do
      echo $fname
      nm=$(echo $fname | sed 's/_\([0-9][0-9]\)\([0-9][0-9]\)\([0-9][0-9]\)/_\2\3\1/g' )
      cnt=$(($cnt+1));
      if [ $cnt -ne 1 ]
      then
          mv $nm  ./bkup
          echo "$nm moved to backup"
      fi
   done
done

I have tested and it worked fine...
