Getting around `eval` in the various scripts

[mulle-nat]

Hi

first of all, thanks for the project. It looks like it can save me a lot of time maintaining my containerized commands :+1:

I was curious, so I had a look at the scripts. I am wondering: in the generated code from a distrobox-export you are quoting the arguments to run the command with eval when outside of the container. But why not just run the command directly ?

exec /usr/local/bin/distrobox-enter -n <whatever> -- /usr/bin/<whatever> "%@"

A way to avoid eval when constructing command lines

When constructing arguments, you could use set -- to avoid lot of quoting. This example runs its arguments with the '-l' option through the ls command:

#! /bin/sh -x

[ $# -eq 0 ] && echo "usage: $0 <filename>..." && exit 1

# build from back to front
ls_args="-l -d"
set -- ${ls_args} "$@"
set -- ls "$@"
"$@"
