Using "$lineMo" does not work (tried it)
Using '$lineMO' also does not work because the ' ' negates the meaing of $ and searches for the string $lineMO in the file rather than the contents of the variable $lineMO

I'm looking for SED equivalent for grep -w -f. All I want is to search a list of patterns from a file. Also If the pattern doesn't match I do not want "null returned", rather I would prefer some text as place holder say "BLANK LINE" as I intend to process the output file based on line number.

Hey guys,
I have a file with an ID which I'm using to grep out the original record from another file. Problem is I have special characters in the original file, and grep is returning only a partial record. How can I get around this?

workqueue_enqueue
WORKQUEUE(9) BSD Kernel Developer's Manual WORKQUEUE(9)
NAME
workqueue -- simple do-it-in-thread-context framework
SYNOPSIS
#include <sys/workqueue.h>
int
workqueue_create(struct workqueue **wqp, const char *name, void (*func)(struct work *, void *), void *arg, pri_t prio, int ipl, int flags);
void
workqueue_enqueue(struct workqueue *wq, struct work *wk, struct cpu_info *ci);
void
workqueue_destroy(struct workqueue *wq);
DESCRIPTION
The workqueue utility routines are provided to defer work which is needed to be processed in a thread context.
workqueue_create() creates a workqueue. It takes the following arguments:
wqp Specify where to store the created workqueue.
name The name of the workqueue.
func The function to be called for each work.
arg An argument to be passed as a second argument of func.
prio The priority level for the worker threads.
ipl The highest IPL at which this workqueue is used.
flags The value of 0 indicates a standard create operation, however the following flags may be bitwise ORed together:
WQ_MPSAFE Specifies that the workqueue is multiprocessor safe and does its own locking, otherwise the kernel lock will be held while
work will be processed.
WQ_PERCPU Specifies that the workqueue should have a separate queue for each CPU, thus the work could be enqueued on concrete CPUs.
workqueue_enqueue() enqueues the work wk into the workqueue wq.
If the WQ_PERCPU flag was set on workqueue creation, the ci argument may be used to specify the CPU on which the work should be enqueued.
Also it may be NULL, then work will be enqueued on the current CPU. If WQ_PERCPU flag was not set, ci must be NULL.
The enqueued work will be processed in a thread context. A work must not be enqueued again until the callback is called by the workqueue
framework.
workqueue_destroy() destroys a workqueue and frees associated resources. The caller should ensure that the workqueue has no work enqueued
beforehand.
RETURN VALUES
workqueue_create() returns 0 on success. Otherwise, it returns an errno(2).
CODE REFERENCES
The workqueue subsystem is implemented within the file sys/kern/subr_workqueue.c.
