```

## Method Detail

### setShell

```java
public void setShell(java.lang.String shell)

```

Sets the shell to use when running commands (applies to UNIX only)

**Parameters:**

- `shell` - the shell to use. E.g. "csh". If null is specified, then the command is issued directly without a shell

### getShell

```java
public java.lang.String getShell()

```

Returns the shell used to run programs

### setJobListener

```java
public PHXRuntime setJobListener(com.phoenix_int.aserver.util.IPHXProcessJobInfoListener jobListener)

```

### getJobListener

```java
public com.phoenix_int.aserver.util.IPHXProcessJobInfoListener getJobListener()

```

### exec

```java
public java.lang.Process exec(java.lang.String cmd,
                              java.lang.String baseDir)
                       throws java.io.IOException

```

Runs the specified command. The function first switches to the proper directory.

**Parameters:**

- `cmd` - the command to run
- `baseDir` - the directory to run it in.

**Throws:**

- `java.io.IOException` - thrown if the command cannot be executed

### exec2

```java
public PHXProcess exec2(java.lang.String cmd,
                        java.lang.String baseDir,
                        boolean addErrorChecks)
                 throws java.io.IOException

```

Runs the specified command. The function first switches to the proper directory. The PHXProcess which is returned has the ability to track the process and sub-processes in a somewhat platform independent way.

**Parameters:**

- `cmd` - the command to run
- `baseDir` - the directory to run it in.
- `addErrorChecks` - Whether to insert error checks after each command in multi-line commands.

**Throws:**

- `java.io.IOException` - thrown if the command cannot be executed
