setFileSize :: RawFilePath -> FileOffset -> IO ()unix System.Posix.Files.ByteString Truncates the file down to the specified length. If the file was larger than the given length before this operation was performed the extra is lost. Note: calls truncate.
setFileTimes :: RawFilePath -> EpochTime -> EpochTime -> IO ()unix System.Posix.Files.ByteString setFileTimes path atime mtime sets the access and modification times associated with file path to atime and mtime, respectively. Note: calls utime.
setFileTimesHiRes :: RawFilePath -> POSIXTime -> POSIXTime -> IO ()unix System.Posix.Files.ByteString Like setFileTimes but timestamps can have sub-second resolution. Note: calls utimensat or utimes. Support for high resolution timestamps is filesystem dependent with the following limitations:
- HFS+ volumes on OS X truncate the sub-second part of the timestamp.
-
unix System.Posix.Files.ByteString Set group ID on execution.
setOwnerAndGroup :: RawFilePath -> UserID -> GroupID -> IO ()unix System.Posix.Files.ByteString setOwnerAndGroup path uid gid changes the owner and group of path to uid and gid, respectively. If uid or gid is specified as -1, then that ID is not changed. Note: calls chown.
setSymbolicLinkOwnerAndGroup :: RawFilePath -> UserID -> GroupID -> IO ()unix System.Posix.Files.ByteString Acts as setOwnerAndGroup but does not follow symlinks (and thus changes permissions on the link itself). Note: calls lchown.
setSymbolicLinkTimesHiRes :: RawFilePath -> POSIXTime -> POSIXTime -> IO ()unix System.Posix.Files.ByteString Like setFileTimesHiRes but does not follow symbolic links. This operation is not supported on all platforms. On these platforms, this function will raise an exception. Note: calls utimensat or lutimes. Support for high resolution timestamps is filesystem dependent with the following limitations:
- HFS+ volumes on OS X truncate the sub-second part of the timestamp.
-
unix System.Posix.Files.ByteString Set user ID on execution.
setFdMode :: Fd -> FileMode -> IO ()unix System.Posix.Files.PosixString setFdMode fd mode acts like setFileMode but uses a file descriptor fd instead of a FilePath. Note: calls fchmod.
setFdOwnerAndGroup :: Fd -> UserID -> GroupID -> IO ()unix System.Posix.Files.PosixString Acts as setOwnerAndGroup but uses a file descriptor instead of a FilePath. Note: calls fchown.
