Hi I received this request from a user and could not find the solution. I would like to know if someone already solved this: "At the command prompt I used to be able to type the first letter of a line command and then by using the up arrow key, scroll through all of the line commands, that begin with that letter, that I had previously executed." It's a machine with CentOS-5.3, x86_64, and tcsh-6.14-14.el5, but his shell is 'csh'. Thanks Marcelo
