1. 新建search.sh指令碼，寫入以下shell指令碼：

#!/bin/sh
# lazy find
# GNU All-Permissive License
# Copying and distribution of this file, with or without modification,

# notice and this notice are preserved.  This file is offered as-is,

## 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

2. 賦予指令碼可執行許可權：

chmod +x search.sh

3. 使用

sh search.sh hello ## 在當前目錄下遍歷搜尋帶hello關鍵字的所有檔案

sh search --path /usr/local hello ##在指定目錄/usr/local下搜尋帶關鍵字hello的所有檔案

4. 新增到系統快捷命令

vim ~/.bashrc ##編輯系統命令

新增：

alias lf=/root/find_file.sh ##自定義檔案搜尋指令碼

儲存生效：

. ~/.bashrc

5. 使用快捷命令搜尋檔案

lf hello 或者 lf --path /usr/local hello
