Premise · What I want to realize

I've getting an error into writing a Dockerfile, so I'm worried about a getting error. That command is cp.

testing environment

  • base container image centos:7
  • My laptop is MacBook Pro (it may not need info, isn't it?)

What I did

the Dockerfile is here,

FROM centos:7 # Official centos image. this is a comment for asking here.

ENV JAVA_HOME=/usr/lib/jvm/java-11-openjdk \
    SCALA_HOME=/usr/local/scala \
    SCALA_VERSION=scala-2.13.0

WORKDIR /usr/local/lib/

Problems occurring · Error messages

the getting error is,

cp: invalid option -- 'e'
Try 'cp --help' for more information.

umm.., I've completely understand the error. I haven't cp alias too.

Could you please help me? If you need more information, feel free asking me.

i had the same error as you because i wrote the command as below

sudo find /home/usersdata -type f -user mark -exec cp -p -parents {} /official ;

  • the parameters parents should --parents instead of -parents

For some reasons the error does not provide explicitly what is wrong.

Hope it helps you
