Bash Script: Read One Character At A Time

To read one character at a time in a Bash script, you can use the read command with the -n 1 option to read a single character from standard input.

Here is an example of how to use the read command to read one character at a time in a Bash script:

# Read a single character
read -n 1 key

# Print the character that was read
echo "Key pressed: $key"

This script will read a single character from standard input and store it in the key variable. The echo command is then used to print the character that was read.

You can use this script to read input from the user and process it one character at a time. For example, you could use it to implement a simple menu system or to read a password input.

Keep in mind that the read command is a powerful tool that can be used to read input from the user and process it in various ways. You can use the various options available with the read command to customize its behavior and read input in different formats.
