Hi,

i need to delete entire print lines... Like my file is having some printf statements. I need to remove all the printf lines in my file. These printf statements might be in a single line or it might stretch for 2 lines also( in this case these two lines have to be deleted as these two line together a printf statement). say my file is as follows:


$cat testfile.txt
1. pritnf 'this is first line ' .
2. printf ' this is second line '
'this is continuous line ' .
3. print ' this is 3rd line '
' it is still there '
' now its over ' .
4. set a = b
5. MOVE A TO B

output :
4. set a = b
5. MOVE A TO B

Please let me know how to delete those printf lines using sed in unix.

Thanks in advance..

MOVE(7) 						  PostgreSQL 9.2.7 Documentation						   MOVE(7)

NAME
MOVE - position a cursor SYNOPSIS
MOVE [ direction [ FROM | IN ] ] cursor_name where direction can be empty or one of: NEXT PRIOR FIRST LAST ABSOLUTE count RELATIVE count count ALL FORWARD FORWARD count FORWARD ALL BACKWARD BACKWARD count BACKWARD ALL DESCRIPTION
MOVE repositions a cursor without retrieving any data. MOVE works exactly like the FETCH command, except it only positions the cursor and does not return rows. The parameters for the MOVE command are identical to those of the FETCH command; refer to FETCH(7) for details on syntax and usage. OUTPUTS
On successful completion, a MOVE command returns a command tag of the form MOVE count The count is the number of rows that a FETCH command with the same parameters would have returned (possibly zero). EXAMPLES
BEGIN WORK; DECLARE liahona CURSOR FOR SELECT * FROM films; -- Skip the first 5 rows: MOVE FORWARD 5 IN liahona; MOVE 5 -- Fetch the 6th row from the cursor liahona: FETCH 1 FROM liahona; code | title | did | date_prod | kind | len -------+--------+-----+------------+--------+------- P_303 | 48 Hrs | 103 | 1982-10-22 | Action | 01:37 (1 row) -- Close the cursor liahona and end the transaction: CLOSE liahona; COMMIT WORK; COMPATIBILITY
There is no MOVE statement in the SQL standard. SEE ALSO
