Sfdisk is your friend.

Having made my living for some months doing this, I offer the general
below guidelines.
1. Study sfdisk man page closely.
2. Look especially for the parts where it can output disk and partition
information in the form that can be re-read by sfdisk.
3. Use that information in a script (with your preferred combo of bash,
perl, (g)awk, bc, dc, ...) to locate total size, amount used, start/end
points, etc.
4. Calculate desired changes.
5. Apply to the saved information.
6. Run sfdisk reading the modified output from sfdisk.
7. sfdisk -R (IIRC) to re-read the partition information.
Alternately, steps 6/7 could be replaced with gparted if you structure
the results properly.
