我正在尝试用 zsh (Linux Mint 21.3 “Virginia”) 编写一个脚本，将文件从 $source 移动（或复制）到 $target，但结果却令人困惑。我使用 yad 文件对话框来选择文件并命名目标目录。我能做到的最好的就是只将最终选择复制到空目标。
以下是整个脚本
setopt -x
setopt -v
autoload -Uz zmv
# WARNING Just because two or more files from different sources have identical names does not mean
#that the files are identical.
declare -a array
array=$(yad --width=600 --height=800 \
--title="Choose files to move." \
--file --multiple --separator='\n')
echo $array
target=$(yad --width=600 --height=800 \
--title="Choose destination." \
--file --directory)
echo "target="$target
# The file you wish to move may already exist in the target directory.
# If you do not want to overwrite it you can use
# mv -n
# mv --no-clobber
# or
# mv --backup=numbered
# Clumsy, but better than nothing, and doesn't give me what I want.
# That is why I wrote this script, it adds an incremented number to the name.
# eg <movie>.<ext>
# eg <movie>_copy1.<ext>
# eg <movie>_copy2.<ext>
# Yes, I could use brackets but they are illegal characters and I have a renamer
# that would remove them.
# You can't just use <filename>.$ext to check if the file exists in target because
# you'll miss any existing copies. You have to account for iteration.
for filename in $array; do
unset x
# decompose filename
# just name without path
filename=$filename:t
echo
echo
echo "filename="$filename
echo
echo
# name without extension
shortname=${filename%.*}
echo "shortname="$shortname
echo
echo
# extension
ext=${filename##*.}
echo
echo
echo "ext="$ext
# The key here is to rename the file (if necessary) BEFORE copying it to target instead
# of after.
# Does file already exist in $target? Count them.
x=$(find $target -iname "$shortname*.$ext" | wc -c)
echo
echo
echo "x="$x
# If no file exists, move to target.
# If one file exists then $x will return "1". Think of it as
# <filename>_copy0.<ext>,
# this makes the file you wish to move
# <filename>_copy1.<ext>, - the value of $x.
case $x in
0) cp $filename $target
sleep .2
;;
*) mv $filename $shortname_copy$x.$ext
cp $filename $target
sleep .2
;;
esac
done
exit 0
这是使用相同参数两次运行脚本的终端输出。

在我看来，这个逻辑似乎有效。在移动文件之前，计算目标中的迭代次数并重命名文件，但我想我的 shell 脚本编写能力不足以胜任这项任务。欢迎任何帮助。
