Input file for optimization

[hameed1987]

Dear All,
I would like to make optimization for a perovskite structure by changing pressure from 1 to -1 Gpas,

Please one of you tell me how to increase pressure in abinit input file for this optimization?

I mean how to write or mention this in input file, in order to make optimization for every pressure
