Question

I have a script that renames files with.JPEG ext to .jpg but if it renames one and it already exists I need it to create a new directory called duplicates and move the file there instead of overwritting it.

Answer 1

我没有对此进行测试:

foreach j (*.JPEG *.JPG)
    set target = $j:r.jpg
    if (-e $target) then
        mkdir -p duplicates  # create directory if it doesn t already exist
        mv $j duplicates/$target
    else
        mv $j $target
    endif
end

But consider whether csh is the best tool for this kind of thing:

Answer 2

这将使你能够测试档案的存在:

test -e img.jpg

你可以测试档案的存在,如果确实存在,则将其移至复制件。 a. 创建一个称为重复的夹:

mkdir duplicates

希望会有所帮助。
