There are a lot of useful tools in Linux and wc is one of them, this tool let us know the number of:
Lines, words or characters that we could find in a text file, its use is very simple:
wc [OPTION]… [FILE]…
Where the options are
-c, --bytes print the byte counts
print the character counts -l, --lines print the newline counts -L, --max-line-length print the length of the longest line -w, --words print the word counts
Suppose you have a file called mytextfile.txt and would like to know how many lines and words it have just enter:
wc -l -w mytextfile.txt
The output will be like this.
7334 22002 /home/user/mytextfile.txt
So it has 7334 lines and 22002 words.
