Examples ls *.txt | wc -l | tee /dev/tty count.txt In the above example the ls command would list all .txt files in the current directory, take a word count (wc) by the amount of lines (-l) and the output displayed to the /dev/tty (terminal) will be sent to the count.txt. Note: Because the above example did not take advantage of the -a or append option if the count.txt file already existed it would have been overwritten. Related commands cat |
