Regular Expresions

Hello friends,
this is yerra i am using openSUSE10.3,i am getting problems with regular expressions in shell,regular expresions are Not working for shell based commands as comapared to Fedora

ex:-man pthread_mutex* should giveone among the man pages for the functions like pthread_mutex_lock etc.


Kindly give the solution

Doesn't work that way because REs are evaluated wrt the filesystem.

pthread_mutex* is not a file, it is the name of a man page. So there is no list of filenames to evaluate the RE against.

For 'man' the usable option is apropos, see 'man man'.

~> man -k pthread_mutex
pthread_mutex_destroy (3p) - destroy and initialize a mutex
pthread_mutex_getprioceiling (3p) - get and set the priority ceiling of a mutex (REALTIME THREADS)
pthread_mutex_init (3p) - destroy and initialize a mutex
pthread_mutex_lock (3p) - lock and unlock a mutex
pthread_mutex_setprioceiling (3p) - get and set the priority ceiling of a mutex (REALTIME THREADS)
pthread_mutex_timedlock (3p) - lock a mutex (ADVANCED REALTIME)
// more and more lines follow
