There is a way, but it's too complicated to fit into the column. in the syntax column means "not existing". Needless to say you can increase the rate further ( -L 8000), and the command becomes very similar to cat, with the output appearing instantaneously.įor more information see man pv or the Ubuntu manpages online.To write the output of a command to a file, there are basically 10 commonly used ways. The example below uses a high rate (300), but if you choose a low rate such as -L 50, it will appear as if the computer is typing out the file for you. With pv you can literally print the file to the screen, and choose the rate ( -L) at which it appears. Monitor the progress of data through a pipe.pv will copy each supplied FILE in turn to standard output (- means standard input), or if no FILEs are specified just standard input is copied.

It is in the repositories and so can be installed with sudo apt-get install pv if you don't have it already.Īs the man page notes, pv is very often used to As we seem to be listing all available alternatives of displaying any text file in the terminal, it would be quite fun to introduce pv as technically one valid (but unusual) method, although I would normally use cat instead for most things.
