Leaving aside the question of why one might want to do this, Unix 101 should show you many ways to do it. For example, sed -n -e 's/.*PG_VERSION /PG_VERSION /p' -e /PG_VERSION/q config.log Please don't cross-post questions like this, especially when it's not really a PostgreSQL question at all. cheers andrew Kuriakose, Cinu Cheriyamoozhiyil wrote: > Hi All, > > I am giving the command > > cat config.log|grep -w 'PG_VERSION' > > Which gives the following Output: > > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > | #define PG_VERSION "8.3beta2" > #define PG_VERSION "8.3beta2" > > But the output that I would require is > > PG_VERSION "8.3beta2" that should occur only once, can anyone please > tell me the command to get this output. > > Thanks in advance > > Regards > Cinu Kuriakose > > > ---------------------------(end of broadcast)--------------------------- > TIP 9: In versions below 8.0, the planner will ignore your desire to > choose an index scan if your joining column's datatypes do not > match > >
