[SOLVED] Deleting not fully empty direcrory

Finally I found out most ASAP solution (ASAP -> As Simple As Possible).

Because name of directory I want to remove (and all its content) is a date of creation, because it is surveillance system. So using "date" command I can count number of days from 1970-01-01. If number of days is grater then 30 form today, just remove whole dir. The code below:

Code:

#!/bin/sh
#
ilosc_dni=30
#
katalog=/share/CACHEDEV2_DATA/kamery
FILES_Front_mp4=/share/CACHEDEV2_DATA/kamery/Kamery/Front/FI9900P_00626E660E5A/record
FILES_Front_jpg=/share/CACHEDEV2_DATA/kamery/Kamery/Front/FI9900P_00626E660E5A/snap
FILES_Bok_mp4=/share/CACHEDEV2_DATA/kamery/Kamery/Bok/FI9900P_00626E682B7A/record
FILES_Bok_jpg=/share/CACHEDEV2_DATA/kamery/Kamery/Bok/FI9900P_00626E682B7A/snap
#
#
x=`date +"%s"` ; actual=`echo $(( $x / 3600 / 24 ))`
for i in $FILES_Front_mp4 $FILES_Front_jpg $FILES_Bok_mp4 $FILES_Bok_jpg
do 
for data in `find $i -maxdepth 1 -name '20*'|grep -o '.\{8\}$'`
do
x=`date -d $data +"%s"` ; curr=`echo $(( $x / 3600 / 24 ))`
dni=$((actual-curr))
[ $dni -gt $ilosc_dni ] && rm -rf $i/$data 2>/dev/null
done
done

Isnr it ASAP ?

no, it isn't ASAP, because:

Code:

curr=`echo $(( $x / 3600 / 24 ))`
# should be written as:
curr=$(( $x / 3600 / 24 ))

for example.

OK, right small difference ;-)

I was going to suggest just having your script delete the entire directory then recreate it. that gets rid of any hidden files within it. But it looks to me you said something about only needing to get rid of a few files. You could as a work around. Use a different Logic.

Code:

1. find all files you want to keep.
2. create temp dir, move them into same said dir. if they are on the same partition. Depending on the over all size, that shouldn't take to long to do.
3. delete 'old' dir.
4. rename 'temp' dir to the same one you just deleted.
5. done.

the time required to do this should not be too much longer. as long as the directory in question being worked on is not receiving new data within it while in any part of that script running.
