executeOut

Arguments

:: MonadIO m

=> FilePath

command as filename, e.g. ls

-> [String]

arguments to the command

-> Maybe FilePath

chdir to this path

-> m CapturedProcess

Execute the given command and collect the stdout, stderr and the exit code. The command is run in a subprocess.

execLogged

Arguments

:: (MonadReader env m, HasSettings env, HasLog env, HasDirs env, MonadIO m, MonadThrow m)

=> FilePath

thing to execute

-> [String]

args for the thing

-> Maybe FilePath

optionally chdir into this

-> FilePath

log filename (opened in append mode)

-> Maybe [(String, String)]

optional environment

-> m (Either ProcessError ())

captureOutStreams

Arguments

:: IO a

the action to execute in a subprocess

-> IO CapturedProcess

Capture the stdout and stderr of the given action, which is run in a subprocess. Stdin is closed. You might want to race this to make sure it terminates.

actionWithPipes :: ((Fd, Fd) -> IO b) -> IO b

cleanup :: [Fd] -> IO ()

createRegularFileFd :: FileMode -> FilePath -> IO Fd

Create a new regular file in write-only mode. The file must not exist.

exec

Arguments

:: MonadIO m

=> String

thing to execute

-> [String]

args for the thing

-> Maybe FilePath

optionally chdir into this

-> Maybe [(String, String)]

optional environment

-> m (Either ProcessError ())

Thin wrapper around executeFile.

toProcessError :: FilePath -> [String] -> Maybe ProcessStatus -> Either ProcessError ()

chmod_755 :: (MonadReader env m, HasLog env, MonadIO m) => FilePath -> m ()

newFilePerms :: FileMode

Default permissions for a new file.

isBrokenSymlink :: FilePath -> IO Bool

Checks whether the binary is a broken link.
