Traversing thru dirs and deleting files based on date
Hi Folks

I am pretty new to unix and shellscripting.
I need help on writing logic on traversing recursively through a set of directories under a top-level folder and delete files(mostly text) which are 1 month old.
Can you people help me on this?

Thanks a lot
Ravi

This should do what you're looking for:

DAYS=30

echo 'Daily cleanup of backup directories more than' $DAYS 'days old'

if [ -d /wasdata ]
then

FILES=`find /wasdata2 -type f -mtime +$DAYS`

for f in $FILES
do
echo 'Deleting' $f
rm $f
done

fi

You can do the same in a single command and log it too using the tee command or redirecting the output to a file.

Code:
find /your_path -type f -mtime +30 -exec rm -f {} \; | tee delete.log

With zsh:

Code:
rm -- **/*(.m+30)

FILES=`find /somedir -type f -mtime +$DAYS`

for f in $FILES
do
rm $f

done


Some filenames have spaces and this is causing an error while deleting.
Any way to rectify this ?

Thanks

Yes, use my zsh example Smilie
Or:

- if your find/xargs have the print0/-0 option, you could:

Code:
find /somedir -type f -mtime +$DAYS -print0|xargs -0 rm

- otherwise:

Code:
find /somedir -type f -mtime +$DAYS|while IFS= read;do rm -- "$REPLY";done

or (if your find supports it):

Code:
find /somedir -type f -mtime +$DAYS -exec rm {} +
