導致現在有不同的格式出現
1. 去除空白
2. 將底線 ( _ ) 換成dash ( - )
經過一番查詢,終於發現最簡單的方法 - rename指令
它是基於 Perl 底下發展出來的
NAME
rename - renames multiple files
SYNOPSIS
rename [ -v ] [ -n ] [ -f ] perlexpr [ files ]
DESCRIPTION
"rename" renames the filenames supplied according to the rule specified
as the first argument. The perlexpr argument is a Perl expression
which is expected to modify the $_ string in Perl for at least some of
the filenames specified. If a given filename is not modified by the
expression, it will not be renamed. If no filenames are given on the
command line, filenames will be read via standard input.
For example, to rename all files matching "*.bak" to strip the
extension, you might say
rename 's/\.bak$//' *.bak
To translate uppercase names to lower, you'd use
rename 'y/A-Z/a-z/' *
重點來了,因為它是用 Perl expression,要稍微了解一下它的方式
不過指令本身的格式很簡單:
rename 's/要改的部份/要變成的部份/' 目的檔案
所以操作的方式為
rename 's/ //' *
rename 's/_/-/' *
這樣就可以了
