| 18 | DESCRIPTION |
| 19 | ----------- |
| 20 | The `lttng disable-channel` command disables one or more channels |
| 21 | previously enabled with the man:lttng-enable-channel(1) command |
| 22 | which belong to: |
| 23 | |
| 24 | With the option:--session='SESSION' option:: |
| 25 | The recording session named 'SESSION'. |
| 26 | |
| 27 | Without the option:--session option:: |
| 28 | The current recording session (see man:lttng-concepts(7) to learn |
| 29 | more about the current recording session). |
| 30 | |
| 31 | See man:lttng-concepts(7) to learn more about channels. |
| 32 | |
| 33 | The `disable-channel` command disables one channel per 'CHANNEL' |
| 34 | argument. |

| 37 | channel once its recording session has been started (see |
| 38 | man:lttng-start(1)) at least once. |
