Bash 日志配置
使用输出重定向实现日志记录
使用 echo 命令加输出重定向实现日志记录：
1echo "This is a line." >> shell.log
2echo "This is another line." >> shell.log
自定义函数实现日志记录
简单日志记录函数
1#!/bin/bash
2
3function log() {
4 msg=$1
5 echo $msg >> shell.log
6}
7
8log "This is a line."
9log "This is another line."
日志分级
1#!/bin/bash
2
3function info() {
4 echo -e "\033[32m$*\033[0m"
5}
6
7function warning() {
8 echo -e "\033[33m$*\033[0m"
9}
10
11function error() {
12 echo -e "\033[31m$*\033[0m"
13}
14
15function logging() {
16 level=$1
17 shift
18 case $level in
19 "info")
20 info "$*";;
21 "warning")
22 warning "$*";;
23 "error")
24 error "$*";;
25 *)
26 echo "$*";;
27 esac
28}
29
30# Test
31logging info "This is an info message."
32logging warning "This is a warning message."
33logging error "This is an error message."
日志效果如下：
