--------------------------------------
Summary: Don't use bash shopt in the wrapper script
Key: JCLOUDS-283
URL: https://issues.apache.org/jira/browse/JCLOUDS-283
Project: jclouds
Issue Type: Bug
Components: jclouds-scriptbuilder
Affects Versions: 1.6.2
Reporter: Ignasi Barrera
Assignee: Ignasi Barrera
Fix For: 1.7.0
Some images with a bash shell don't support the "shopt" command used in the
wrapper script, so it should be removed to make the generated scripts more
portable. Some default devstack images don't support the command (see [1]), so
fixing this may help significantly testing jclouds with openstack.
The used at the moment are:
* xpg_echo: Turns on/off the interpretation of the backslash (to interpret or
not the '\n', for example).
* expand_aliases: Turns on/off the alias expanding. This allows to define alias
in the script and use them alter.
The first one can be removed, if all calls to the "echo" command that need to
interpret the backslash are changed to "echo -e".
The second one, could be removed if the alias definitions are replaced by bash
functions, which should be a direct change.
