| 54 | * <pre> | |
| 55 | * If /C or /K is specified, then the remainder of the command line after | |
| 56 | * the switch is processed as a command line, where the following logic is | |
| 57 | * used to process quote (") characters: | |
| 58 | * | |
| 59 | * 1. If all of the following conditions are met, then quote characters | |
| 60 | * on the command line are preserved: | |
| 61 | * | |
| 62 | * - no /S switch | |
| 63 | * - exactly two quote characters | |
| 64 | * - no special characters between the two quote characters, | |
| 65 | * where special is one of: &<>()@ˆ| | |
| 66 | * - there are one or more whitespace characters between the | |
| 67 | * the two quote characters | |
| 68 | * - the string between the two quote characters is the name | |
| 69 | * of an executable file. | |
| 70 | * | |
| 71 | * 2. Otherwise, old behavior is to see if the first character is | |
| 72 | * a quote character and if so, strip the leading character and | |
| 73 | * remove the last quote character on the command line, preserving | |
| 74 | * any text after the last quote character. | |
| 75 | * </pre> | |
| 76 | * <p/> | |
| 77 | * <p> | |
| 78 | * Always quoting the entire command line, regardless of these conditions | |
| 79 | * appears to make Windows processes invoke successfully. | |
