The wc commands stands for word count
nuclearegg69@zenbook-f13:~$ ls
a b c echo empty inNano3 inNano3.txt inNanoRenamed inNanoSymlink testRen testRen2
nuclearegg69@zenbook-f13:~$ nano a
nuclearegg69@zenbook-f13:~$ wc a
5 5 58 a
When we pass a file as an argument to wc
and run it, it gives us three numbers: the first is the line count, the second is the word count, the third is the bytes count.
You can add options to wc to limit what you want
nuclearegg69@zenbook-f13:~$ wc -l a
5 a
nuclearegg69@zenbook-f13:~$ wc -w a
5 a
nuclearegg69@zenbook-f13:~$ wc -c a
58 a
nuclearegg69@zenbook-f13:~$ wc -m a
58 a
-l
option gives you the lines only
-w
words only
-c
bytes only
-m
characters only
