shell script output redirection

goral.j · 01-27-2005, 01:37 AM

I am having a lot of trouble figuring out how to output the contents of a command to a file and also having it appear within the terminal. All the standard redirection I know of, such as ping google.com > output.out, will simply give the impression that the computer has locked up while it prints to file.

Is there anyway to have the output printed within the terminal and to the file simultaneously?

Thanks in advance,

Jeff

You want the tee command (man tee)

For example:

Code:

date | tee somefile.txt

You'll see the output of the date command on the screen, and the same information will be written to somefile.txt.

Also:
tee -a if you want to append a file
and not clobber it.
