One Day One GNU/Linux Command
=============================
tee - Read from stdin and write to stdout and files
Summary :
Tee will copy the stdin to file(s) and also to stdout output.
Actually tee is doing the redirection. The following ASCII
art(!) will shows "How Tee works".
STDIN >---+---> STDOUT
|
|
|
V
File(s)
Examples :
$ tee -- Read from stdin and write into stdout.
$ tee f1 f2 -- Read from stdin and write into stdout, f1 & f2.
$ tee -i myfile -- Same as above. But it will ignore the interrupt
signals (Ex: ctrl+C).
$ tee -a myfile -- Read from stdin and write into stdout & append
to myfile.
$ who | tee myfile -- Store the output of who to myfile and also
write to stdout.
$ ls -1 | tee f1 f2 | wc -l -- Store the ls output in f1, f2 and
write the count of all files on stdout.
NOTE:
STDIN - Standard Input - Keyboard
STDOUT - Standard Output - Screen
Read : man tee
HTH :)
