echo with acbuild run writes a file on the host #310

Closed jharshman closed 7 years ago

jharshman commented 7 years ago

AcBuild Version: 

$ acbuild version
acbuild version v0.4.0
appc version 0.8.5

Given the following line:

acbuild run -- echo 'eval "$(rbenv init -)"' | tee /etc/profile.d/rbenv.sh

a file is generated on the host machine running acbuild rather than inside the container. The end goal here is to have eval "$(rbenv init -)" written into the file /etc/profile.d/rbenv.sh within the container image.

Is this misuse on my part or a bug?

What's happening here is the shell on the host is interpreting the pipe and running the tee command, instead of those things being passed into acbuild. You can invoke a shell inside of acbuild to do the pipe logic for you if you wish:

acbuild run -- /bin/sh -c 'echo \'eval "$(rbenv init -)"\' | tee /etc/profile.d/rbenv.sh'

Thanks for the quick reply! Seems to be something funky going on with the quotes though. Here's what got it working.

acbuild run -- /bin/sh -c "echo 'eval \"\$(rbenv init -)\"' | tee /etc/profile.d/rbenv.sh"
