27 | * | ||
28 | * This is a new implementation of 'cat' which aims to be SUSv3 compliant. | ||
29 | * | ||
30 | * Changes from the previous implementation include: | ||
31 | * 1) Multiple '-' args are accepted as required by SUSv3. The previous | ||
32 | * implementation would close stdin and segfault on a subsequent '-'. | ||
33 | * 2) The '-u' options is required by SUSv3. Note that the specified | ||
34 | * behavior for '-u' is done by default, so all we need do is accept | ||
35 | * the option. | ||
