# log it!
#
# Use it to log a command to a file. Useful when you run commands in the terminal and want to keep history of its output.
#
# usage: log_it [args]
#
# example: log_it df -h
#
# the above command will add both stdout and stderr to a log file called 2024-02-20_16-08-53-df_-h.log

log_it() {
    printf -v date '%(%Y-%m-%d_%H-%M-%S)T' -1
    log_file_suffix=$(echo "$@" | sed -e 's/[^A-Za-z0-9._-]/_/g')
    log_file="$date-$log_file_suffix.log"

    echo "running command: $@" | tee -a "$log_file"
    echo "logging on $log_file" | tee -a "$log_file"
    echo "--" | tee -a "$log_file"

    # stdout and stderr
    $@ 2>&1 | tee -a "$log_file"
}

That's cool!
