Why cp indicate "is not a directory" on one server and it's okay on another server

When I execute this command on my server : 

cp *index.html saveIndex/$(date +%Y%m%d-%H%M)Index.html

The shell indicates :

cp: target 'saveIndex/20180110-0934Index.html' is not a directory

However, this command function on my computer.

Because you have multiple *index files, and your command looks like: cp index.html 1index.html bla-blaindex.html saveIndex/20180110-0934Index.html and it could be executed if only last argument is a directory, not file name.

You can or run cp *index.html saveIndex/, or add seconds at the date for new filename and create the script like that:

#!/bin/bash
for ifile in *index.html
do
    cp "${ifile}" saveIndex/$(date +%Y%m%d-%H%M%S)Index.html
    sleep 1
done

sleep 1 will allows you to get unique names, but you can use any another suffix you prefer ($RANDOM for example or last time modified/changed date, inode of each file) to avoid sleep 1 waiting.

Inode example:

#!/bin/bash
for ifile in *index.html
do
    cp "${ifile}" saveIndex/$(stat -c %i "${ifile}")-$(date +%Y%m%d-%H%M%S)Index.html
done
