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：

vim创建一个脚本文件

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

代码如下：

 1 [root@izgt88z6l1kvd7z ~]# vim Anyfile.sh
 2 [root@izgt88z6l1kvd7z ~]# cat Anyfile.sh 
 3 #!/bin/sh
 4 
 5 ## help function
 6 
 7 function helpu {
 8     echo " "
 9     echo "Fuzzy search for filename."
10     echo "$0 [--match-case|--path] filename"
11     echo " "
12     exit
13 }
14 
15 ## set variables
16 
17 MATCH="-iname"
18 SEARCH="."
19 
20 ## parse options
21 
22 while [ True ]; do
23 if [ "$1" = "--help" -o "$1" = "-h" ]; then
24     helpu
25 elif [ "$1" = "--match-case" -o "$1" = "-m" ]; then
26     MATCH="-name"
27     shift 1
28 elif [ "$1" = "--path" -o "$1" = "-p" ]; then
29     SEARCH="${2}"
30     shift 2
31 else
32     break
33 fi
34 done
35 
36 ## sanitize input filenames
37 ## create array, retain spaces
38 
39 ARG=( "${@}" ) 
40 set -e
41 
42 ## catch obvious input error
43 
44 if [ "X$ARG" = "X" ]; then
45     helpu
46 fi
47 
48 ## perform search
49 
50 for query in ${ARG[*]}; do
51     /usr/bin/find "${SEARCH}" "${MATCH}" "*${ARG}*"
52 done

然后给它执行的权限，我给最大的777

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

试一下，搜索sed

1 [root@izgt88z6l1kvd7z ~]# ./Anyfile.sh sed
2 ./administration/git/git-2.26.2/t/chainlint.sed
3

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。
```
alias 'lol'='/root/Anyfile.sh'
```
按x退出执行一下

 . ~/.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
