unbuffer ? unbuffer output |
unbuffer program [ args ] |
unbuffer disables the output buffering that occurs when program output is redirected. For example, suppose you are watching the output from a fifo by running it through od and then more. |
od -c /tmp/fifo | more |
You will not see anything until a full page of output has been produced. You can disable this automatic buffering as follows: unbuffer od -c /tmp/fifo | more |
The man page is longer than the program. |
