Copy files searched with find command using xargs command I'd like to copy the files searched using find command into the current directory. I am executing the following command-line:

    # find linux books
$ find ~ -type f -iregex '.*linux.*\.pdf' -print0 | xargs -0 echo
    # Expected output on STDOUT
../Books/LinuxCollection/Linux_TLCL-17.10.pdf ../Richard Blum, Christine Bresnahan - Linux Command Line and Shell Scripting Bible, 3rd Edition - 2015.pdf ..


I wish to copy the files to the current directory using the cp command. Here is the command that I entered:

$ find ~ -type f -iregex '.*linux.*\.pdf' -print0 | xargs -0 cp .


However, I get an error as shown below upon executing the above command:

usage: cp [-R [-H | -L | -P]] [-fi | -n] [-apvXc] source_file target_file
       cp [-R [-H | -L | -P]] [-fi | -n] [-apvXc] source_file ... target_directory


I have also tried to resolve the issue by using command substitution. Here is the command that I tried:

$ cp $(find ~ -type f -iregex '.*linux.*\.pdf' -print0) .


However, I get another error as shown below upon executing the above command:

cp: Blum,: No such file or directory


How do I accomplish the desired result using the xargs command?
xargs appends its input to the command, so you are basically running cp . source_file. Use

find ~ -type f -iregex '.*linux.*\.pdf' -print0 | xargs -I '{}' -0 cp '{}' .


instead.
