[Chimera-users] Command line

I searched the online documents and was unable to find out how to perform certain actions via the command line. Can you let me know how to perform the following commands via the command line: Color secondary structure (and set color for Helix, Strand & Coil) Create a text file with a summary of attributes (ie. # of ions, # of ligands, # of chains, areaSAS for each selected residue) Color surface based on hydrophobicity Thanks!
