Variants

Read(Option<u16>, W)

Open a file for reading, e.g. [n]< file.

Write(Option<u16>, W)

Open a file for writing after truncating, e.g. [n]> file.

ReadWrite(Option<u16>, W)

Open a file for reading and writing, e.g. [n]<> file.

Append(Option<u16>, W)

Open a file for writing, appending to the end, e.g. [n]>> file.

Clobber(Option<u16>, W)

Open a file for writing, failing if the noclobber shell option is set, e.g. [n]>| file.

Heredoc(Option<u16>, W)

Lines contained in the source that should be provided by as input to a file descriptor.

DupRead(Option<u16>, W)

Duplicate a file descriptor for reading, e.g. [n]<& [n|-].

DupWrite(Option<u16>, W)

Duplicate a file descriptor for writing, e.g. [n]>& [n|-].
