How do I copy files from Folder A to Folder B based on Text File C with bash?

  • folderA: source folder with image files only, e.g. image01.png, image02.png etc. There are no space in the image names, only dash or underscore
  • folderB: destination folder with nothing inside.
  • C.txt: is a UTF16 encoded raw text file, inside the text file stored the file names that I want to copy from folderA and these file names are line by line

    image01.png
    image02.png
    image04.png
    

Specific paths are

  • ~/Documents/C.txt
  • ~/Documents/folderA/
  • ~/Documents/folderB/

    What do you mean "based on text file C"? Can you provide an example of how you expect this to work? – Allan Jan 15 at 14:38

    I'm glad that you found a solution but the solution doesn't match your question- "How do I copy files from one directory to another based on a text file with filenames" – fd0 Jan 16 at 16:40
  • I don't think so fd0, I do exactly this : I changed directory to folderA then 'cp argument1 argument2' where argument 1 is a chain of file names that I want and separated by a space; argument2 is the destination. Talking is unreal, test it in your local host. – gcplau Jan 16 at 16:44
  • Please don‘t add the answer to the Question, Post it as an answer below instead. It might also help to make sure the formatting is correct, and to show how you use C.txt in your solution. – nohillside Jan 16 at 16:49

Assuming your file C contains a list of file names to copy:

A="~/Documents/folderA"
B="~/Documents/folderB"
while IFS= read -r file; do
    cp "${A}/${file}" "${B}/"
done < ~/Documents/c.txt

should do the trick.

  • cd ~/ to change director cp (paste chain of file names here now) (then, type a space) then type your destination folder path/name (hit return) – gcplau Jan 16 at 15:59

  • @gcplau What exactly doesn‘t work? – nohillside Jan 20 at 10:42
