I have got 2 FileSystems visible when I use df -k or mount command /u00 and /u01 of 5 GB and 10 GB respectively. Can you please let me know exact commands to execute for below:

1) Delete /u00
2) Modify /u01 from 10 GB size to 5 GB size
3) Create /u02 (new fs) of size 10 GB

Thank you - by using bash the issue of shells resolved.
