EXIT STATUS

*0*::
    Success

*1*::
    Command error

*2*::
    Undefined command

*3*::
    Fatal error

*4*::
    Command warning (something went wrong during the command)


ENVIRONMENT
-----------
`LTTNG_ABORT_ON_ERROR`::
    Set to `1` to abort the process after the first error is
    encountered.

`LTTNG_HOME`::
    Path to the LTTng home directory.
+
Defaults to `$HOME`.
+
Useful when the Unix user running the commands has a non-writable home
directory.

`LTTNG_MAN_BIN_PATH`::
    Absolute path to the manual pager to use to read the LTTng
    command-line help (with man:lttng-help(1) or with the
    nloption:--help option) instead of `/usr/bin/man`.

`LTTNG_SESSION_CONFIG_XSD_PATH`::
    Path to the directory containing the `session.xsd` tracing session
    configuration XML schema.

`LTTNG_SESSIOND_PATH`::
    Absolute path to the LTTng session daemon binary (see
    man:lttng-sessiond(8)).
+
The genoption:--sessiond-path general option overrides this environment
variable.
+
NOTE: The man:lttng-create(1) command can spawn an LTTng session daemon
automatically if none is running. See man:lttng-sessiond(8) for the
environment variables affecting the execution of the session daemon.


FILES
-----
`$LTTNG_HOME/.lttngrc`::
    Unix user's LTTng runtime configuration.
+
This is where LTTng stores the name of the Unix user's current tracing
session between executions of man:lttng(1). man:lttng-create(1) and
man:lttng-set-session(1) set the current tracing session.

`$LTTNG_HOME/lttng-traces`::
    Default output directory of LTTng traces in local and snapshot
    modes.
+
Override this path with the nloption:--output option of the
man:lttng-create(1) command.

`$LTTNG_HOME/.lttng`::
    Unix user's LTTng runtime and configuration directory.

`$LTTNG_HOME/.lttng/sessions`::
    Default directory containing the Unix user's saved tracing session
    configurations (see man:lttng-save(1) and man:lttng-load(1)).

+{system_sessions_dir}+::
    Directory containing the system-wide saved tracing session
    configurations (see man:lttng-save(1) and man:lttng-load(1)).

NOTE: `$LTTNG_HOME` defaults to the value of the `HOME` environment
variable.
