- The M(shell) module takes the command name followed by a list of space-delimited arguments.
|
|
It is almost exactly like the M(command) module but runs
|
|
the command through a shell (C(/bin/sh)) on the remote node.

|
notes:
|
|
- If you want to execute a command securely and predictably, it may be
|
|
better to use the M(command) module instead. Best practices when writing
|
|
playbooks will follow the trend of using M(command) unless M(shell) is
|
|
explicitly required. When running ad-hoc commands, use your best
|
|
judgement.
|
|
- To sanitize any variables passed to the shell module, you should use
|
|
"{{ var | quote }}" instead of just "{{ var }}" to make sure they don't include evil things like semicolons.
