crontab task
user@xxx.xxx.xxx.121:~/workarea/EXP_IMP>% crontab -l
0 3 * * * /starhome/iu/workarea/EXP_IMP/main_exp.sh

main script
user@xxx.xxx.xxx.121:~/workarea/EXP_IMP>% less main_exp.sh
#!/bin/bash
./export_all_db.sh
./zip_all_export_files.sh

export all schemas
user@xxx.xxx.xxx.121:~/workarea/EXP_IMP>% less export_all_db.sh
#!/bin/bash
