yes, actually it is better because we avoid looping!
and how it would be possible to use array provided in the externall shell?
#!/bin/bash
pdb="final.pdb"
output=$(pwd)
# array given in bash
chains_array=('A' 'B')
# chains are cutted by pymol
pymol -c -d "
cmd.load('${pdb}')
cmd.alter('chain ' + '+'.join($chains_array), 'chain=\"\"')
cmd.set('pdb_use_ter_records', 1)
cmd.set('retain_order', 1)
cmd.save('output_without'+"".join($chains_array) + '.pdb')
"
