WC Linux – (Count Lines, Words, Characters ) in Linux with best examples

WC command in the Linux/ Unix world is used to find out the Number of  Lines, Characters, and words. In this tutorial, we are going to learn how to use this command with examples.

Step 1: WC Command Basic Usage

If we don’t parse any parameters while use “wc ” command, then it will display “number of lines”, “number of words”  and “number of bytes” of a file. Execute the following command to get the information from myserverfix.txt file.

wc myservefix.txt

the output of this command is the following:

11  16 1500   myserverfix.txt

In the output

  • 11 is the number of lines.
  • 16 is the number of words.
  • 1500 is the number of bytes.

 

Step 2:  Count Number of Words in a File

To count the number of words in a file, we need to pass an additional parameter ‘w’ with the command. which is the following.

wc -w myserverfix.txt

the output of this command

22 myserver.txt

Here 22 is the number of words in the myserver.txt file.

 

Step 3: Count Number of Lines in a File.

To count the number of lines in a file, we need to parse another parameter in the “wc” command. Execute the following command in the terminal.

wc -l myserverfix.txt

The output of this command is following.

22 myserverfix.txt

Here 22 is the number of lines in the file.

 

Step 4:  Check Number of Characters in a  File.

To check the number of characters in a file execute the ‘wc’ command with -c parameters. This will display the information, execute the following command.

wc -c myserverfix.txt

The output of this command is following.

134 myserverfix.txt

 

Step 5: Check the Length of the Longest line in a file.

wc -L myserverfix.txt

It will display the length of the Longest Line in a File. However, if you want to explore more options that WC command provides, just execute the following command in the terminal.

wc --help

The output of this command is going to be the following.

Usage: wc [OPTION]... [FILE]...
  or:  wc [OPTION]... --files0-from=F

more than one FILE is specified.  With no FILE, or when FILE is -,
read standard input.
  -c, --bytes            print the byte counts
  -m, --chars            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
      --help			display this help and exit
      --version			output version information and exit
