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_rwlockattr_destroy
pthread_rwlockattr_init(3T)pthread_rwlockattr_init(3T)NAME
pthread_rwlockattr_init(), pthread_rwlockattr_destroy() - initialize or destroy a read-write lock attributes object
SYNOPSIS PARAMETERS
attr Pointer to the read-write lock attributes object to be initialized or destroyed.
DESCRIPTION
initializes the read-write lock attributes object attr with the default value for all attributes. The attributes object describes a read-
write lock in detail and is passed to the read-write lock initialization function.
When a read-write lock attributes object is used to initialize a read-write lock, the values of the individual attributes determine the
characteristics of the new read-write lock. Attributes objects act like additional parameters to object initialization.
After a read-write lock attributes object has been used to initialize one or more read-write lock, any function affecting the attributes
object does not affect the previously initialized read-write locks.
The read-write lock attributes and their default values are:
The default value is
If an initialized read-write lock attributes object is reinitialized, undefined behavior results.
destroys the read-write lock attributes object attr. The destroyed read-write lock attributes object ceases to exist and its resources are
reclaimed. Referencing the object after it has been destroyed results in undefined behavior. A destroyed read-write lock attributes object
can be reinitialized using the function
Read-write locks which have been already initialized using this attributes object are not affected by the destruction of the read-write
lock attributes object.
RETURN VALUE
Upon successful completion, and return 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 and functions return the corresponding error number:
[ENOMEM] There is insufficient memory available in which to initialize attr.
[EINVAL] The value specified by attr is invalid.
