If tdc is executing test cases inside a namespace, only the
first command in a compound statement will be executed inside
the namespace by tdc. As a result, the subsequent commands
are not executed inside the namespace and the test will fail.
Example:
for i in {x..y}; do args="foo"; done && tc actions add $args
The namespace execution feature will prepend 'ip netns exec'
to the command:
ip netns exec tcut for i in {x..y}; do args="foo"; done && \
tc actions add $args
So the actual tc command is not parsed by the shell as being
part of the namespace execution.
Enclosing these compound statements inside a bash invocation
with proper escape characters resolves the problem by creating
a subshell inside the namespace.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
