In this way the program vimdiff reads the user input instead of the stream coming from the pipe.

tty
tty(1) User Commands tty(1)NAME
tty - return user's terminal name
SYNOPSIS
tty [-l] [-s]
DESCRIPTION
The tty utility writes to the standard output the name of the terminal that is open as standard input. The name that is used is equivalent
to the string that would be returned by the ttyname(3C) function.
OPTIONS
The following options are supported:
-l Prints the synchronous line number to which the user's terminal is connected, if it is on an active synchronous line.
-s Inhibits printing of the terminal path name, allowing one to test just the exit status.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of tty: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 Standard input is a terminal.
1 Standard input is not a terminal.
>1 An error occurred.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWcsu |
+-----------------------------+-----------------------------+
|CSI |Enabled |

SEE ALSO isatty(3C), ttyname(3C), attributes(5), environ(5), standards(5)DIAGNOSTICS
not on an active synchronous line
The standard input is not a synchronous terminal and -l is specified.
not a tty
The standard input is not a terminal and -s is not specified.
NOTES
The -s option is useful only if the exit status is wanted. It does not rely on the ability to form a valid path name. Portable applications
should use test -t.
