I usually download with filezilla in the directory /Public/Downloads on my nas.
I made a script executed by filezilla when download queue is finished, so all my downloads are moved to /Public/Downloads/Completed. My directory /Public/Downloads contains also two files and three directories that must not be moved.
folder.jpg
log.txt
Temp
Cache
Completed
I tried this command:
find /Public/Downloads/* -maxdepth 1 | grep -v Completed | grep -v Cache | grep -v Temp | grep -v log.txt | grep -v folder.jpg | xargs -i mv {} /Public/Downloads/Completed
This works for downloaded files and folders named without special characters: they are moved to /Public/Downloads/Completed
But when there is a <space> or an à or something else special, xarg is complaining unmatched single quote; by default quotes are special to xargs unless you use the -0 option
I've searched a solution by myself but haven't find something for my needs combining find, grep and xargs for files and directories.
How do I have to modify my command ?

Answer 1

This is just a suggestion for your change strategy and not about xargs. You only need the bash shell and mv for the external tool.
#!/usr/bin/env bash
shopt -s nullglob extglob
array=(
folder.jpg
log.txt
Temp
Cache
Completed
)
to_skip=$(IFS='|'; printf '%s' "*#(${array[*]})")
for item in /Public/Downloads/*; do
[[ $item == $to_skip ]] && continue
echo mv -v "$item" /Public/Downloads/Completed/ || exit
done
Remove the echo if you think that the output is correct.
Add the -x e.g. set -x (after the shebang) option to see which/what the code is doing or bash -x my_script, assuming my_script is the name of your script.

Answer 2

So i've changed my strategy for a loop using a temporary text file:
#!/bin/bash
ls -p /Public/Downloads | grep -v "Cache/" | grep -v "Temp/" | grep -v "Completed/" | grep -v 'log.txt' | grep -v 'folder.jpg' >/Public/Downloads/Completed/temp.txt
cat /Public/Downloads/Completed/temp.txt |\
while IFS='' read -r CURRENT || [ -n "$CURRENT" ]; do
mv /Public/Downloads/"$CURRENT" /Public/Downloads/Completed
done
rm /Public/Downloads/Completed/temp.txt
1) I write a list of directories and files to be moved with "ls" in "temp.txt"
2) Each line of "temp.txt" is passed into the $CURRENT variable. So each file and directory is moved one by one with "mv". The variable $CURRENT is double quoted in the mv command in case of "space" character in the name of the directory or the file
3) "temp.txt" is deleted

Answer 3

Based on OP input, the main issue is files name with "special" characters, including space. Two options:
If none of the input files has embedded new line in the file name (which is the case), the problem can be addressed by explicit specification of the delimited string to new line (-d '\n'). See below
If any of the files can contain new line in the name, the whole pipeline has to use zero-terminated strings. Does not seems to be the case here.
find /Public/Downloads/* -maxdepth 1 |
grep -v Completed |
grep -v Cache |
grep -v Temp |
grep -v log.txt |
grep -v folder.jpg |
xargs -d '\n' -i mv {} /Public/Downloads/Completed
