finding location of modules shown from "module list"

my .bashrc has a module add shared cmsh cmd slurm line, followed only by a module load slurm. how can I find the underlying configuration of the module program and **specifically** where the modules cmsh and cmd live ? I want to find out where the path /cm/local/apps/cmd/bin/cmsh is getting added to my PATH.. which somehow gets lost after doing particular yum installs where I think some dependency items come along for the ride and upset this configuration that results in whenever a new terminal is opened that .bashrc *module add items* all fails. I assume the module add cmsh causes that PATH modification how do I find that particular cmsh.? "module" file ?
