Method Detail

getExec

public static final java.io.File getExec(java.lang.String path)

Check if the specified file path is a valid file.

Parameters:

path - The file path to check if it is valid.

Returns:

Pointer to this file, if this file is valid. Otherwise return null.

findPathExec

public static final java.lang.String findPathExec(java.lang.String prog)

This method browses current path to search for a file. Typically this should be an executable, but it is impossible under Java to check if this file has the execution bit on. Apart from the user defined $PATH variable, common bin-directory places are searched.

Parameters:

prog - The file to check if it exists in the system $PATH

Returns:

The path of the specified program. If it is not found, the program name is returned.
