Extended grep use and example on UNIX and AIX server

 How AIX and UNIX admin use extended grep with example.

----------------------------------------------------------------------------

AIX and UNIX

Lets observe following example where AIX admin wanted to check path of  storage disk.

#lspath |grep -w "hdisk2"

#lspath |grep -w "hdisk3"

#lspath |grep -w "hdisk4"

Instead of typing above single command for getting path details, AIX admin can use following extended grep.

#lspath |grep -E " hdisk2 |hdisk 3 |hdisk4"

above command will display path information for hdisk2 ,hdisk3 and hdisk4.

Thanks !!!!!
