I think it's fairly obvious what I'm trying to do here
# Rename Log File
ExecStartPre=/bin/find /data/db/log/*.log -type f -exec mv {} {}.`date +"%Y%m%d-%H%M"` \;
# gzip past log files (is post becuase might take a long time)
ExecStartPost=/bin/find /data/db/log/*.log.2* -type f -mtime +2 -exec gzip {} \;
# delete really old stuff
ExecStartPost=/bin/find /data/db/log/*.log.2*.gz -type f -mtime +90 -delete
these get "Executable path contains special characters, ignoring"
Any suggestions what I'd need to do to get these working?
