What happens is that it prints the header on to the terminal and the rest is piped out to the file output.
Also found out that -gk9 works for scientific notation. -nrk9 did not work as expected.
Hi!!!
i have two files "tushar20090429200000.txt" and "tushar_err20090429200000.txt"
The numeric part here is date and time.
So this part of file keeps changing after every hour.
I want to extract the numeric part from the both file names and compare them whether they are equal or not.

Hey everybody,
I'm trying to sort scientific numbers in a descending order using the command

alter_foreign_data_wrapper
ALTER FOREIGN DATA WRAPPER(7) PostgreSQL 9.2.7 Documentation ALTER FOREIGN DATA WRAPPER(7)NAME
ALTER_FOREIGN_DATA_WRAPPER - change the definition of a foreign-data wrapper
SYNOPSIS
ALTER FOREIGN DATA WRAPPER name
[ HANDLER handler_function | NO HANDLER ]
[ VALIDATOR validator_function | NO VALIDATOR ]
[ OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ]) ]
ALTER FOREIGN DATA WRAPPER name OWNER TO new_owner
ALTER FOREIGN DATA WRAPPER name RENAME TO new_name
DESCRIPTION
ALTER FOREIGN DATA WRAPPER changes the definition of a foreign-data wrapper. The first form of the command changes the support functions or
the generic options of the foreign-data wrapper (at least one clause is required). The second form changes the owner of the foreign-data
wrapper.
Only superusers can alter foreign-data wrappers. Additionally, only superusers can own foreign-data wrappers.
PARAMETERS
name
The name of an existing foreign-data wrapper.
HANDLER handler_function
Specifies a new handler function for the foreign-data wrapper.
NO HANDLER
This is used to specify that the foreign-data wrapper should no longer have a handler function.
Note that foreign tables that use a foreign-data wrapper with no handler cannot be accessed.
VALIDATOR validator_function
Specifies a new validator function for the foreign-data wrapper.
Note that it is possible that after changing the validator the options to the foreign-data wrapper, servers, and user mappings have
become invalid. It is up to the user to make sure that these options are correct before using the foreign-data wrapper.
NO VALIDATOR
This is used to specify that the foreign-data wrapper should no longer have a validator function.
OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ] )
Change options for the foreign-data wrapper. ADD, SET, and DROP specify the action to be performed. ADD is assumed if no operation is
explicitly specified. Option names must be unique; names and values are also validated using the foreign data wrapper's validator
function, if any.
new_owner
The user name of the new owner of the foreign-data wrapper.
new_name
The new name for the foreign-data wrapper.
EXAMPLES
Change a foreign-data wrapper dbi, add option foo, drop bar:
ALTER FOREIGN DATA WRAPPER dbi OPTIONS (ADD foo '1', DROP 'bar');
Change the foreign-data wrapper dbi validator to bob.myvalidator:
ALTER FOREIGN DATA WRAPPER dbi VALIDATOR bob.myvalidator;
COMPATIBILITY
ALTER FOREIGN DATA WRAPPER conforms to ISO/IEC 9075-9 (SQL/MED), except that the HANDLER, VALIDATOR, OWNER TO, and RENAME clauses are
extensions.
