我爲自己寫了這個。它速度快,允許正則表達式查找和替換,並支持「試運行」。
如果您在Mac上,它可以使用applescript將Finder中的當前文件夾挑出爲目標文件夾。
umxRenameFile <- function(baseFolder = "Finder", findStr = NA, replaceStr = NA, listPattern = NA, test = T, overwrite = F) {
# uppercase = u$1
if(baseFolder == "Finder"){
baseFolder = system(intern = T, "osascript -e 'tell application \"Finder\" to get the POSIX path of (target of front window as alias)'")
message("Using front-most Finder window:", baseFolder)
} else if(baseFolder == "") {
baseFolder = paste(dirname(file.choose(new = FALSE)), "/", sep = "") ## choose a directory
message("Using selected folder:", baseFolder)
}
if(is.na(listPattern)){
listPattern = findStr
}
a = list.files(baseFolder, pattern = listPattern)
message("found ", length(a), " possible files")
changed = 0
for (fn in a) {
findB = grepl(pattern = findStr, fn) # returns 1 if found
if(findB){
fnew = gsub(findStr, replace = replaceStr, fn) # replace all instances
if(test){
message("would change ", fn, " to ", fnew)
} else {
if((!overwrite) & file.exists(paste(baseFolder, fnew, sep = ""))){
message("renaming ", fn, "to", fnew, "failed as already exists. To overwrite set T")
} else {
file.rename(paste(baseFolder, fn, sep = ""), paste(baseFolder, fnew, sep = ""))
changed = changed + 1;
}
}
}else{
if(test){
# message(paste("bad file",fn))
}
}
}
message("changed ", changed)
}
