4. Examples
By default if you pass file as a argument to wc command it prints number of lines, words and characters:
wc /etc/passwd
To instruct wc command to print only number of words contained within file we can use -w option:
wc -w /etc/passwd
Similarly if we need only number of lines we would use -l option:
wc -l /etc/passwd
For number of characters we need to use -c option:
wc -m /etc/passwd
wc can also print out a number of bytes within file:
wc -c /etc/passwd
