避免命令名稱衝突情況，使用 alias

alias 替代名稱=原命令名稱

找尋 java 檔案

test@test:/$ fdfind -e java
home/test/Demo.java

查找 password 名稱檔案，有高亮效果

test@test:/$ fdfind 'password'

查找 path 類型檔案，名稱包含 password

fdfind -e path 'password'

預設不區分大小寫，可以加-tf區分大寫，注意小寫不行喔!!

test@test:~$ touch Demo
test@test:~$ touch demo
test@test:~$ ls
demo  Demo
test@test:~$ fdfind demo
Demo
demo
test@test:~$ fdfind -tf demo
Demo
demo
test@test:~$ fdfind -tf Demo
Demo

找尋後執行命令，像是找尋後刪除

test@test:~$ fdfind -tf Demo -x rm {}
test@test:~$ ls
demo
