Number of words multiplied by the number of lines in Linux

[sjalesho]

You can do that with "wc",

1. wc - l for the number of lines
2. wc -w for the number of words

Hoe should one combine these 2, let's say if I want to multiply the number of words with the number of lines from file a and b respectively?

Thanks

Look into bc and dc.

For a file named e.c:

echo `expr $(cat e.c|wc -l) \* $(cat e.c|wc -c)`
