[英]Changing suffix on bash file backup
I have been trying to change the suffix on my backup files using the --suffix
function but I'm not quite sure how to do it. 我一直在尝试使用
--suffix
函数更改备份文件上的后缀,但是我不确定该怎么做。 Currently this line of code 目前这行代码
find ./$1 -name "IMG_****.JPG" -exec cp --backup=t {} ./$2 \;
searches the first command line argument directory for images in the IMG_****.JPG
format and copies them to the directory entered second, making copies of any files with duplicate names and adding the =t
suffix to the end giving IMG_****.JPG.~1~
etc. Instead of .~1~
I would like to add something like .JPG
, any ideas on how to use the --suffix
to do this? 在第一个命令行参数目录中搜索
IMG_****.JPG
格式的图像,然后将其复制到第二个输入的目录中,以任何名称重复的文件进行复制,并在末尾添加=t
后缀,以提供IMG_****.JPG.~1~
等.~1~
我想添加.JPG
而不是.JPG
,关于如何使用--suffix
执行此操作的任何想法?
The backup suffix is '
~
', unless set with--suffix
orSIMPLE_BACKUP_SUFFIX
.备份后缀为“
~
”,除非使用--suffix
或SIMPLE_BACKUP_SUFFIX
设置。
It should be pretty obvious from this sentence that supplying --suffix
is equivalent to setting SIMPLE_BACKUP_SUFFIX
, which as its name suggests only applies to simple backups (ie, --backup=simple
or --backup=never
). 从这句话中可以很明显地看出,提供
--suffix
等效于设置SIMPLE_BACKUP_SUFFIX
,顾名思义,该设置仅适用于简单备份(即--backup=simple
或--backup=never
)。 Eg, 例如,
> touch src dst
> cp --backup=simple --suffix=.bak src dst
> ls src* dst*
dst dst.bak src
However, you are requesting numbered backups through --backup=t
, so the suffixes you will get will always be .~1~
, .~2~
, etc., unaffected by --suffix
. 但是,您请求通过编号备份
--backup=t
,所以你会得到后缀总是会.~1~
.~2~
等,通过影响--suffix
。
