Quiet

Quiet[expr]
evaluates expr "quietly", without actually outputting any messages generated.

Quiet[expr, {s₁::t₁, s₂::t₂, ...}]
quietens only the specified messages during the evaluation of expr.

Quiet[expr, "name"]
quietens only the named group of messages.

MORE INFORMATION

Quiet has attribute HoldAll.

Quiet[expr, m_off, m_on] specifies that messages in the list m_off should not be generated, but those in m_on should be.

Explicit message names of the form s::t can be mixed with named message groups.

Quiet constructs can be nested; the innermost specification for a particular message is the one used.

The operation of Check and related message functions is not affected by being inside Quiet.

If Quiet is used inside functions like Check, messages suppressed by Quiet are not tested by Check.

In Quiet[expr, "name"], possible named message groups are given by $MessageGroups.

Quiet[expr] is equivalent to Quiet[expr, All]. Quiet[expr, None, All] switches on all messages.
