搜索文件/目录的shell脚本

• 在 Windows 下，有一款非常实用的神器，叫作 Everything ，它可以在极短的时间里，搜索出来你所想要的文件/目录
• Linux 下也有一些类似于 everything 的神器，比如：locate，Catfish，Tracker，等等。这些工具也十分强大，但是自己动手丰衣足食，说干就干：

1. vim创建一个脚本文件

2. [root@izgt88z6l1kvd7z ~]# vim Anyfile.sh

   代码如下：

3. [root@izgt88z6l1kvd7z ~]# vim Anyfile.sh
   [root@izgt88z6l1kvd7z ~]# cat Anyfile.sh 
   #!/bin/sh
   
   ## help function
   
   function helpu {
       echo " "
       echo "Fuzzy search for filename."
       echo "$0 [--match-case|--path] filename"
       echo " "
       exit
   }
   
   ## set variables
   
   MATCH="-iname"
   SEARCH="."
   
   ## parse options
   
   while [ True ]; do
   if [ "$1" = "--help" -o "$1" = "-h" ]; then
       helpu
   elif [ "$1" = "--match-case" -o "$1" = "-m" ]; then
       MATCH="-name"
       shift 1
   elif [ "$1" = "--path" -o "$1" = "-p" ]; then
       SEARCH="${2}"
       shift 2
   else
       break
   fi
   done
   
   ## sanitize input filenames
   ## create array, retain spaces
   
   ARG=( "${@}" ) 
   set -e
   
   ## catch obvious input error
   
   if [ "X$ARG" = "X" ]; then
       helpu
   fi
   
   ## perform search
   
   for query in ${ARG[*]}; do
       /usr/bin/find "${SEARCH}" "${MATCH}" "*${ARG}*"
   done

4. 然后给它执行的权限，我给最大的777

5. [root@izgt88z6l1kvd7z ~]# chmod 777 Anyfile.sh

6. 试一下，搜索sed

7. [root@izgt88z6l1kvd7z ~]# ./Anyfile.sh sed
   ./administration/git/git-2.26.2/t/chainlint.sed
    

9. 使用 alias 命令,来实现别名ss=./Anyfile.sh。为了能够在系统重启之后ss命令依然能使用，我们直接在 .bashrc 里进行修改。

10. alias 'lol'='/root/Anyfile.sh'

    按x退出执行一下

11.  . ~/.bashrc

    再次实验

    [root@izgt88z6l1kvd7z ~]# lol my
    ./administration/git/git-2.26.2/t/t4051/dummy.c
    ./administration/git/git-2.26.2/Documentation/MyFirstObjectWalk.txt
    ./administration/git/git-2.26.2/Documentation/MyFirstContribution.txt
    ./administration/my.cnf
    ./.mysql_history

    ok
