Bash Shell Count Number of Characters In a String or Word

by

In bash, you can count the number of characters in a string or word using the ${#string} syntax. The # operator returns the length of the string.

Here’s an example of how you can use this syntax to count the number of characters in a string:

string="Hello, World!"
char_count=${#string}
echo "The number of characters in the string is: $char_count"

Output:

The number of characters in the string is: 13

In this example, the string “Hello, World!” is assigned to the variable string, and the number of characters in the string is calculated using the ${#string} syntax. The resulting count is stored in the char_count variable, which is then displayed using the echo command.
