I am trying to match a pattern exactly in a shell script. I have tried two methods
awk '/\<mpath${CURR_MP}\>/{print $1 $2}' multipath
perl -ne '/\bmpath${CURR_MP}\b/ and print' /var/tmp/multipath
Both these methods require that I use the escape character. I am guessing that is why... (8 Replies)

pthread_rwlock_unlock
pthread_rwlock_unlock(3T)pthread_rwlock_unlock(3T)NAME
pthread_rwlock_unlock() - unlock a read-write lock.
SYNOPSIS PARAMETERS
rwlock Pointer to the read-write lock to be unlocked.
DESCRIPTION
The function is called by the owner to release the read-write lock referenced by rwlock. Results are undefined if the read-write lock
rwlock is not held by the calling thread.
If this function is called to release a read lock on the read-write lock rwlock and there are other read locks currently held on this read-
write lock, the read-write lock shall remain in the read locked state but without the current thread as one of its owners. If this function
releases the last read lock for this read-write lock, the object shall be put in the unlocked state with no owners.
If this function is called to release a write lock on the read-write lock rwlock, the read-write lock shall be put in the unlocked state
with no owners.
If the call to the function results in the read-write lock becoming unlocked and there are threads waiting to acquire the read-write lock
for writing, the scheduling policy is used to determine which thread shall acquire the read-write lock for writing. If there are threads
waiting to acquire the read-write lock object for reading, the scheduling policy is used to determine the order in which the waiting
threads shall acquire the read-write lock object for reading. If there are multiple threads blocked on rwlock for both read locks and
write locks, it is unspecified whether the readers will acquire the lock first or whether a writer will acquire the lock first.
Results are undefined if this function is called with an uninitialized read-write lock.
RETURN VALUE
Upon successful completion, returns zero. Otherwise, an error number is returned to indicate the error (the variable is not set).
ERRORS
For each of the following conditions, if the condition is detected, the function returns the corresponding error number:
[EINVAL] The value specified by rwlock does not refer to an initialized read-write lock object.
[EPERM] The current thread does not own the read-write lock.
