BASH Function to Error Warnings and Messages with Terminal Colours

July 23, 2021 No Comments bash script

We sometimes need in BASH script to display messages with different format/colour to terminal console. For example, the warnings messages are blue, and error messages are red. We can use the following customize echo functions to display messages of different types. The colours are defined and easily customizable.

terminalColorClear='\033[0m'
terminalColorEmphasis='\033[1;32m'

terminalColorMessage='\033[1;33m'
terminalColorWarning='\033[1;34m'
 
echoDefault() {
    echo -e "${terminalColorClear}$1${terminalColorClear}"
}
 
echoMessage() {
    echo -e "${terminalColorMessage}$1${terminalColorClear}"
}
 
echoWarning() {
    echo -e "${terminalColorWarning}$1${terminalColorClear}"
}
 
echoError() {
    echo -e "${terminalColorError}$1${terminalColorClear}"
}
 
echoError "echoError"
echoWarning "echoWarning"
echoMessage "echoMessage"
echoDefault "echoDefault"
#!/bin/bash

terminalColorClear='\033[0m'
terminalColorEmphasis='\033[1;32m'
terminalColorError='\033[1;31m'
terminalColorMessage='\033[1;33m'
terminalColorWarning='\033[1;34m'

echoDefault() {
    echo -e "${terminalColorClear}$1${terminalColorClear}"
}

echoMessage() {
    echo -e "${terminalColorMessage}$1${terminalColorClear}"
}

echoWarning() {
    echo -e "${terminalColorWarning}$1${terminalColorClear}"
}

echoError() {
    echo -e "${terminalColorError}$1${terminalColorClear}"
}

echoError "echoError"
echoWarning "echoWarning"
echoMessage "echoMessage"
echoDefault "echoDefault"

This will show different messages to console:
