[Bug] GenericContainer doesn’t properly split commands

Module

Core

Testcontainers version

1.17.3

Using the latest Testcontainers version?

Host OS

Docker version

N/A

What happened?

GenericContainer setCommand uses Java String split to build the array of command parts. If the command contains quoted arguments/quoted arguments with escaped quotes, the container fails.

Example command:

/bin/sh test.sh “argument 1” “argument 2”

Relevant log output

@REslim30 Thanks for the insight. I can see where non-POSIX commands could be a probably.

I currently have a workaround in place, so it’s not blocking me.

It actually might be a shell thing. From man bash

DEFINITIONS
       The following definitions are used throughout the rest of this document.
       blank  A space or tab.
       word   A sequence of characters considered as a single unit by the shell.  Also known as a token.
       name   A word consisting only of alphanumeric characters and underscores, and beginning with an alphabetic character or an underscore.  Also referred to as an iden-
              tifier.
       metacharacter
              A character that, when unquoted, separates words.  One of the following:
              |  & ; ( ) < > space tab newline

QUOTING
       Quoting is used to remove the special meaning of certain characters or words to the shell.  Quoting can be used to disable special treatment for special characters,
       to prevent reserved words from being recognized as such, and to prevent parameter expansion.

       Each of the metacharacters listed above under DEFINITIONS has special meaning to the shell and must be quoted if it is to represent itself.

       When the command history expansion facilities are being used (see HISTORY EXPANSION below), the history expansion character, usually !, must be  quoted  to  prevent
       history expansion.

       There are three quoting mechanisms: the escape character, single quotes, and double quotes.
