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

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.

Or ... ask the application not the OS ....

psql> select version() ;
