I have a list of files, with their full paths, one per line in a file "files.txt"
I was trying to move all of those files from their original location to a new directory.
I CDed into the directory where they live now and issued
for file in ~/Desktop/files.txt do mv $file ~/newfolder
but nothing happens. I am sure I am missing something obvious
bash won't read the contents of the file unless you tell it to.
for file in $(cat ~/Desktop/files.txt); do mv "$file" ~/newfolder; done
You need to tell your loop to read the file, otherwise it is just executing:
mv ~/Desktop/files.txt ~/newfolder
In addition, as nerdwaller said, you need separators. Try this:
while read file; do mv "$file" ~/newfolder; done < ~/Desktop/files.txt
If your paths or file names contain spaces or other strange characters, you may need to do this:
while IFS= read -r file; do mv "$file" ~/newfolder; done < ~/Desktop/files.txt
Notice the quotes " around the $file variable.
If the filenames do not contain whitespace:
mv -t dest_dir $(< text.file)
is probably the most concise way.
If there is whitespace in the filenames
while IFS= read -r filename; do mv "$filename" dest_dir; done < test.file
is safe.
I usually do it with
cat filename | xargs -I {} mv {} /new/dir/path
but not sure right now it works with spaces in filenames.
Try this:
python -c "import shutil; [shutil.move(_.strip(), 'new') for _ in open('files.txt').readlines()];"
BASH code (you can script this):
i=0
IFS=$'\n' ## split only on newlines
for line in $(cat files_test.txt)
do
echo "$line"
let ++i ## increment counter
done
unset IFS ## reset IFS to default
printf 'total: %s lines\n' $i
Test (complex file names):
$ pwd; ls -l
/mnt/Vancouver/domains/buriedtruth.com/docs
total 5520
-rw-r--r-- 1 victoria victoria 1537 Feb 14 11:10 files_test.txt
$ cat files_test.txt | wc -l
12
$ i=0
$ IFS=$'\n' ## split only on newlines
$ for line in $(cat files_test.txt)

# Check if the correct number of arguments is provided

file_list="$1"

Save the script in a file, for example, move_files.sh. Make the script executable using the command chmod +x move_files.sh. Then you can run the script by providing the file list and the destination directory as arguments:
./move_files.sh <file_list> <destination_directory>
Replace <file_list> with the path to your file containing the list of filenames, and <destination_directory> with the path to the directory where you want to move the files.
Note: The script assumes that the filenames listed in the file are either absolute paths or relative paths to the current directory. If the file names are relative to a different directory, you may need to modify the script accordingly.
Possibly
mv -t dest_dir $(sed 's|^|"|;s|$|"|' text.file)
also deals with filenames with spaces while still using a single mv command and no loop. Untested.
