Hi Like some others, I have reached the stage of having sourced alc_env.sch [.sh gives unknown switch because rehat uses .sch.] The addaccu then suggests that setenv is needed, and the default shell/bash for rehat doesn't have a setenv command. I think this calls for "configuring the Linuxbox"? Could you please give some instruction to readers on how to do this. i gather that there may be an alternative command in .sh for setenv, but that it would be best if we could be instructed how to use .sch or the better? .tsch, in view of the tuturial asuming a c like shell. I am keen to email with others who are also following tutorial with redhat. Also could someone please announce to the group when Yagle becomes available shortly. Regards Chris
