  10 SYNOPSIS
  11 --------
  12 [verse]
  13 *lttng* ['linkgenoptions:(GENERAL OPTIONS)'] *disable-channel* (option:--kernel | option:--userspace)
  14       [option:--session='SESSION'] 'CHANNEL'[,'CHANNEL']...

  17 DESCRIPTION
  18 -----------
  19 The `lttng disable-channel` command disables one or more channels
  20 previously enabled with the man:lttng-enable-channel(1) command.
  21
  22 A channel always belongs to a tracing session (see man:lttng-create(1)
  23 to create a tracing session). Without the option:--session option, the
  24 `disable-channel` command disables one or more channels of the current
  25 tracing session (see man:lttng-create(1) and man:lttng-set-session(1) to
  26 learn more about the current tracing session).
  27
  28 The `disable-channel` command disables one channel per 'CHANNEL'
  29 argument.
  30
  31 As of LTTng{nbsp}{lttng_version}, you may :not: enable a disabled
  32 channel once its tracing session has ben started (see
  33 man:lttng-start(1)) at least once.
