No, it won't work, we need to find lines containing a "B" at the start, so we need to mention it, a "^B" tells grep to look for lines having B as their first character, hope you got the concept.

sam_initialize
SAM_INITIALIZE(3) Corosync Cluster Engine Programmer's Manual SAM_INITIALIZE(3)
NAME
sam_initialize - Initialize health checking
SYNOPSIS
#include <corosync/sam.h>
cs_error_t sam_initialize (int time_interval, sam_recovery_policy_t recovery_policy);
DESCRIPTION
The sam_initialize function is used to initialize health checking of a process.
Application can have only one instance of SAM. This function must be called before any other of SAM functions. It is recommended to ini-
tialize before the process begins any process initialization.
The time_interval parameter is a timeout in milliseconds before taking recovery action after having not received a healthcheck.
If time_interval parameter is zero, there is no time limit and no healthcheck must be sent by the process. In this operational mode, a
process failure will continue to execute the recovery policy.
The recovery_policy is defined as type:
typedef enum {
SAM_RECOVERY_POLICY_QUIT = 1,
SAM_RECOVERY_POLICY_RESTART = 2,
} sam_recovery_policy_t;
where
SAM_RECOVERY_POLICY_QUIT
on failure, the process will terminate.
SAM_RECOVERY_POLICY_RESTART
on failure, the process will restart.
To perform event driven healthchecking, sam_register(3) and sam_start(3) functions must called. Event driven healthchecking causes the
duplicate standby process running the SAM serve rto periodically request healthchecks from the active process.
RETURN VALUE
This call return CS_OK value if successful, otherwise and error is returned.
ERRORS
CS_ERR_BAD_HANDLE
can happened in case of double initialization.
CS_ERR_INVALID_PARAM
recovery_policy has invalid value.
