[分享]在脚本中使用 alias

fangdingj

在脚本中是可以使用alias 的，只是bash 在非交互式shell中黙认把alias关闭了，打开就是了

以下是测试代码，bash,zsh,ksh 执行结果一样

1. 
   
2. sh=$(readlink -f /proc/$/exe)
   
3. sh=$(basename $sh)
   
4. if [ "$sh" = "bash" ];then
   
5.     shopt -s expand_aliases
   
6. elif [ "$sh" = "zsh" ];then
   
7.     # in my system, this is not needed
   
8.     set +o noaliases
   
9.     # ksh ,what ?
   
10. fi
    
11. alias echo='/bin/echo -e'
    
12. echo "\n\naaa\n\tbbbbbb"
    
13. alias ls='/bin/ls -a'
    
14. ls /
    
15. alias df='/bin/df -h'
    
16. df
