Bash contains features that appear in other popular shells, and some
(file descriptor 2) to the file DIRLIST, while the command
ls 2>&1 > DIRLIST
directs only the standard output to file DIRLIST, because the
-standard error was duplicated as standard output before the standard
-output was redirected to DIRLIST.
+standard error was made a copy of the standard output before the
+standard output was redirected to DIRLIST.
Bash handles several filenames specially when they are used in
redirections, as described in the following table:
Unless otherwise noted, each builtin command documented as accepting
options preceded by `-' accepts `--' to signify the end of the options.
-For example, the `:', `true', `false', and `test' builtins do not
-accept options.
+The `:', `true', `false', and `test' builtins do not accept options and
+do not treat `--' specially. The `exit', `logout', `break',
+`continue', `let', and `shift' builtins accept and process arguments
+beginning with `-' without requiring `--'. Other builtins that accept
+arguments but are not specified as accepting options interpret
+arguments beginning with `-' as invalid options and require `--' to
+prevent this interpretation.
