| | 4 | # Usage: |
| | 5 | # |
| | 6 | # run-in-pagsh [--fg] name command [argument ...] |
| | 7 | # |
| | 8 | # The argument `name' is a short description of the program to call, |
| | 9 | # without any spaces. It is used for making a PID file, which ensures |
| | 10 | # that only one instance of your command is running. |
| | 11 | # |
| | 12 | # The arguments that come afterward specify the command to run and its |
| | 13 | # arguments, if any. |
| | 14 | # |
| | 15 | # If the command will run in the foreground, then you should use the |
| | 16 | # `--fg' argument, making sure that it is the very first argument to |
| | 17 | # run-in-pagsh. |
| | 18 | # |
| | 19 | # Examples: |
| | 20 | # |
| | 21 | # run-in-pagsh interchange ~/interchange/bin/interchange |
| | 22 | # |
| | 23 | # run-in-pagsh --fg clean-mail ~/scripts/clean-mail |
| | 24 | # |
| | 25 | # Make sure that the ~/.run directory exists and is writable. |
| | 26 | # See http://wiki2.hcoop.net/MemberManual/RunningUnattendedCommands |
| | 27 | # for instructions on how to accomplish this. |
