具有完整路径的Linux cp

Question

How to copy file to dir with full file destination path?

When i use:

cp --parents /etc/passwd /tmp

I get an error

cp: illegal option -- - usage: cp [-R [-H | -L | -P]] [-f | -i | -n] [-alpvx] source_file target_file cp [-R [-H | -L | -P]] [-f | -i | -n] [-alpvx] source_file ... target_directory

And if i using this script

for line in "`cat fromDirs.txt`"; do find "$line" -type f \( -name '*good*' -o -exec grep -F "(NODES_'TASK')" {} \; \) -exec cp {} /tmp/ \;; done

maybe there are possibility to concatenate the variables like

-exec cp $line{} /tmp/ \;; done
or
-exec cp {} /tmp/$line \;; done

???

The problem is your version of cp does not accept long options. When it sees --parents it thinks you are trying to use the - option (as well as the p , a , r , etc. options).

You can emulate it like this:

source=/etc/passwd
mkdir -p /tmp/$(dirname $source)
cp $source /tmp/$source
