TIME="$(date +"%d-%m-%Y-%H%M")"
USER=username

DATABASE=dbname
# Directories and dump
/bin/mkdir -p /backup/Mysql/$DATE
/usr/bin/mysqldump -l -F -u $USER --password=$PASSWORD $DATABASE > /backup/Mysql/$DATE/backup_$TIME.sql
# Compressing
/usr/bin/bzip2 /backup/Mysql/*/*.sql
#Removing files older than x days eg: 90 days
for i in `/usr/bin/find /backup/Mysql/ -maxdepth 1 -type d -mtime +90 -print`; do
/bin/echo -e "Deleting old directories $i"; /bin/rm -rf $i; done

Copy/Move files with find
find <path> -name "filename" -exec cp -prf {} /destination/{} \;
find /var/log/ -name "m*" -exec cp -prf {} /tmp/message/{} \;
This will create the same directory structure under /tmp/message, incase you want all subdirectory files under /tmp/message/ remove the {} .

This will remove the *.log files older than 5 days in directory /var/log/
