1.封装函数#!/bin/bash function log(){ echo "$@"}//测试：log "this is a test..."log "today is `date '+%Y-%m-%d'` "2.设置时间日志#!/bin/bash function log(){ echo "$(date '+%Y-%m-%d %H:%M:%S') $@"} log "this is a test..."3.设置日志级别，并输出对应日志#!/bin/bash #日志级别 debug-1, info-2, warn-3, error-4, always-5LOG_LEVEL=3 #调试日志function log_debug(){ content="[DEBUG] $(date '+%Y-%m-%d %H:%M:%S') $@" [ $LOG_LEVEL -le 1 ] && echo -e "\033[32m" ${content} "\033[0m"}#信息日志function log_info(){ content="[INFO] $(date '+%Y-%m-%d %H:%M:%S') $@" [ $LOG_LEVEL -le 2 ] && echo -e "\033[32m" ${content} "\033[0m"}#警告日志function log_warn(){ content="[WARN] $(date '+%Y-%m-%d %H:%M:%S') $@" [ $LOG_LEVEL -le 3 ] && echo -e "\033[33m" ${content} "\033[0m"}#错误日志function log_err(){ content="[ERROR] $(date '+%Y-%m-%d %H:%M:%S') $@" [ $LOG_LEVEL -le 4 ] && echo -e "\033[31m" ${content} "\033[0m"}#一直都会打印的日志function log_always(){ content="[ALWAYS] $(date '+%Y-%m-%d %H:%M:%S') $@" [ $LOG_LEVEL -le 5 ] && echo -e "\033[32m" ${content} "\033[0m"}4.日志写入文件#日志文件LOG_FILE=./log.txtfunction log(){ content="$(date '+%Y-%m-%d %H:%M:%S') $@" echo $content >> $LOG_FILE} |

#!/bin/bash#${FUNCNAME[1]代表调用该函数的函数，$LINENO代表当前代码行号Log(){ local log_level=$1 local log_info=$2 local line=$3 local script_name=$(basename $0) case ${log_level} in "INFO") echo -e "\033[32m$(date "+%Y-%m-%d %T.%N") [INFO]: ${log_info}\033[0m";; "WARN") echo -e "\033[33m$(date "+%Y-%m-%d %T.%N") [WARN]: ${log_info}\033[0m";; "ERROR") echo -e "\033[31m$(date "+%Y-%m-%d %T.%N") [ERROR ${script_name} ${FUNCNAME[1]}:$line]: ${log_info}\033[0m";; *) echo -e "${@}" ;; esac}Log INFO "Install Success"Log WARN "You Can Ignore"Log ERROR "Invalid Param" $LINENO |
