我想重命名子目录中的所有jpeg文件以及子目录名称和jpeg文件,例如
WorkingDirectory/FolderA/ -> a.jpg
WorkingDirectory/FolderB/ -> a.jpg
想要改变为
WorkingDirectory/FolderA/ -> FolderA-a.jpg
WorkingDirectory/FolderB/ -> FolderB-a.jpg
到目前为止,我正在使用
old.names <- list.files(path = ".", pattern = "jpeg$", recursive = TRUE)
new.names <- old.names
new.names = gsub("/", "-", new.names)
new.names = gsub(".jpeg", "", new.names)
final <- data.frame(do.call(cbind,mget(c('old.names','new.names'))))
final$old.names = gsub("", "", final$old.names)
final$new.names = gsub("", "", final$new.names)
file.rename(final$old.names, paste0(final$new.names, ".jpeg"))
我能够重命名文件,但我面对上述代码的问题是,它将所有文件移动到工作目录中,因为它们应保留在子目录中。

上面的例子似乎已经足够了:
old.names <- list.files(path = ".", pattern = "jpeg$", recursive = TRUE)
new.names <- old.names
new.names <- gsub("/", "-", new.names)
new.names <- file.path(dirname(old.names), new.names)
file.rename(old.names, new.names)

您正在从示例代码中的new.names
剥离文件夹名称。
这应该有效:
old.names <- list.files(path = ".", pattern = "jp[e]*g$", recursive = TRUE)
old.names;
#[1] "tmp/FolderA/a.jpg" "tmp/FolderB/b.jpg"
new.names <- sapply(strsplit(old.names, "/"), function(x)
sprintf("%s/%s",
paste0(x[1:(length(x) - 1)], collapse = "/"),
paste0(x[(length(x) - 1):length(x)], collapse = "-")));
new.names;
#[1] "tmp/FolderA/FolderA-a.jpg" "tmp/FolderB/FolderB-b.jpg"
file.rename(old.names, new.names);
说明:在old.names
上拆分"/"
,然后通过将第一个new.names
条目与n-1
(即文件夹)连接起来构建"/"
,然后添加通过将最后一个文件夹名称和旧文件名与"-"
连接而生成的新文件名。
