Hello
the sac program runs with me good but when i write a command with an extension csh like
"plotsolution.csh"
the "permission denied" appear
and when I start this command with sudo "sudo plotsolution.csh"
it keeps to inform me that the "command not found"
knowing that the path and bash files are corrected and the csh pakage is installed succefully
what is the solution for the message "command not found" ?
I am waiting for your response
