28 This command is a filter (see 4.3.3) that copies all text lines from
|
|
|
29 its standard input path to the standard output path
|
|
|
30 <emphasis>and</emphasis> any number
|

34 The example below uses a pipeline and TEE to simultaneously send the
|
|
|
35 output listing of the "dir" command to the terminal, printer, and a
|
|
|
36 disk file:
|
|
|
37 </para>
|
|
|
38 <screen>
|
|
|
39 dir e ! tee /printer /d0/dir.listing
|
|
|
40 </screen>

42 The following example sends the output of an assembler listing to a
|
|
|
43 disk file and the printer:
|
|
|
44 </para>
|
|
|
45 <screen>
|
|
|
46 asm pgm.src l ! tee pgm.list >/printer
|

49 The example below "broadcasts" a message to four terminals:

52 echo WARNING System down in 10 minutes ! tee /t1 /t2 /t3 /t4
