log4bash

Let's face it - plain old echo just doesn't cut it. log4bash is an attempt to have better logging for Bash scripts (i.e. make logging in Bash suck less).

Using log4bash

source the log4bash.sh script at the beginning of any Bash program.

    #!/usr/bin/env bash
    source log4bash.sh

    log "This is regular log message... log and log_info do the same thing";

    log_warning "Luke ... you turned off your targeting computer";
    log_info "I have you now!";
    log_success "You're all clear kid, now let's blow this thing and go home.";
    log_error "One thing's for sure, we're all gonna be a lot thinner.";

    # If you have figlet installed -- you'll see some big letters on the screen!
    log_captains "What was in the captain's toilet?";

    # If you have the "say" command (e.g. on a Mac)
    log_speak "Resistance is futile";
