Script executed by logrotate gives different result than by executing it manually

I want to rotate our application logs using logrotate. After each rotation, it executes a script which moves all rotated logs to another directory. For example in /home/dev/logs/frontend, I have these log files:

webapp1-access.log webapp2-access.log anotherapp3-access.log codename-access.log ... 

And my logrotate config file:

$ cat app.daily /home/dev/logs/frontend/*access.log { rotate 1 daily copytruncate compress notifempty missingok lastaction bash /path/to/script.sh endscript } 

And what script.sh does is to create a directory based on the log file name then move the rotated log file there. The webapp1-access.log would be rotated to webapp1-access.log.1.gz then the script will move it to /x/y/webbapp1/renamed.log.gz. And so on for other rotated logs.

When I tested the logrotate using logrotate -fv /path/to/config, and It works perfectly as I expected. Then I put the logrotate config file to /etc/logrotate.d (as a symlink).

Next day I checked /x/y dir, I got:

webbapp1/ <---- created from initial logrotate -fv webbapp1-access.log/ <---- Unexpected anotherapp3/ <---- created from initial logrotate -fv anotherapp3-access.log/ <---- Unexpected codename/ <---- created from initial logrotate -fv codename-access.log/ <---- Unexpected 

The *-access.log/ dirs are created by the logrotate. But running logrotate -vf config multiple times wont produce that unexpected result. That happens when I leave logrotate do its daily rotation.

Why is this happening? How can I fix this?

script.sh

#! /usr/bin/bash exec 3>> /var/log/archived-log.log [ "${1:-}" = "-d" ] && debug=1 environment="frontend" rotateddir="/home/dev/logs/$environment" destdir="/x/y" [ "${debug:-}" ] && echo "DEST DIR: $destdir" log() { timestamp=$(date +"%Y-%m-%d %H:%M:%S") echo "$timestamp: $1" >&3 } for archive in $rotateddir/*.gz; do [ "${debug:-}" ] && echo "ARCHIVE: $archive" [ "${archive##*/}" = "*.gz" ] && continue base_name=$(basename "$archive") [ "${debug:-}" ] && echo "BASENAME: $base_name" extension="${base_name##*.}" [ "${debug:-}" ] && echo "EXT: $extension" newdir_name="${base_name%-*}" [ "${debug:-}" ] && echo "NEWDIR_NAME: $newdir_name" tanggal=$(stat -c %y "$archive" | cut -d" " -f1 | { read dat; date -d $dat +%Y%m%d; }) #jam=$(stat -c %y "$archive" | cut -d" " -f2 | { read dat; date -d $dat +%H%M; }) newdir_path="$destdir/$newdir_name" [ "${debug:-}" ] && echo "NEWDIR_PATH: $newdir_path" #dest_archive="$newdir_path/$tanggal-$jam.log.$extension" dest_archive="$newdir_path/$tanggal.log.$extension" [ "${debug:-}" ] && echo "DEST_ARCHIVE: $dest_archive" [ ! -d "$newdir_path" ] && { if [ "${debug:-}" ]; then echo "Would create $newdir_path" else mkdir -p "$newdir_path" log "Created directory: $newdir_path" fi } [ ! -f "$dest_archive" ] && { if [ "${debug:-}" ]; then echo "Would move $archive to $dest_archive" else rsync -a --no-owner --no-group --remove-source-files "$archive" "$dest_archive" #cp -u --no-preserve=mode,ownership "$archive" "$dest_archive" && rm -f "$archive" log "Relocated $archive to $dest_archive" fi } rotates=$(ls -1 "$newdir_path" | wc -l ) [ "$rotates" -ge 7 ] && { oldest=$(ls -t "$newdir_path" | tail -1) if [ "${debug:-}" ]; then echo "Would delete the oldest archive: $oldest" else rm -f "$newdir_path/$oldest" log "Deleted oldest archive of $base_name : $oldest" fi } done exit 0 

Update

I still don't know why this happens, but finally I decided to run the script by cron few minutes after rotation.

I suspect that this part of my "script.sh" newdir_name="${base_name%-*}" is not evaluated well by logrotate. But again, it worked as expected if I run it forcefully using logrotate -fv config
