I can't get the at command to work. I've tried all kinds of stuff and either it can't find the file, or creates a job in the at que, and then fails to run it. For example: at 2:10pm today < /usr/my_c/showenv showenv is entered as a job in the at que, but never runs. The que is empty after 2:10pm. at -f /my_c/curs/hello 2:10pm today Again, its entered as a job, but when execution time comes all I get is an error message saying it couldn't find the file. Both hello and showenv are C executable programs with root permissions. I'm executing at as root on the command line. I've also tried a simple script called ruff. #!/bin/sh ehco "Hello. This is a Test." I gave ruff chmod 777 ruff Tried to get at to run ruff with at -f /usr/my_c/ruff 3:15pm today It was placed in the at que. I saw it as job 5 using atq. But when the time came, nothing happened and the que emptied. Could someone tell me what I'm doing wrong?
