This has got to be an easy one for the command line experts. Could someone please tell me how to run the chown utility, so as to change permissions of a folder to read & write for the "currently logged in user"? I guess I am looking for a variable for the username, since I will be running this command as part of a shell script. I do not wish to specify a username, which would make it possible for me to run the script on any computer for any logged in user. Thanks in advance.
