| 164 | | While start commands that make use of shell syntax for multiple commands and file redirection will generally work, syntax errors will cause them to fail silently. Because of this, and because containerized experiments cannot have as long a start command string, we recommend that if you are doing anything more complex than calling a single program, you script this and run the script from the per-expriment directory or your home directory. |

Because of this, and because containerized experiments cannot have as long a start command string, we recommend that if you are doing anything more complex than calling a single program, create a simple script and run the script from the per-expriment directory or your home directory. This makes it more likely that the log files created by containers will have useful debugging information. |
