Hi,

I thought about it and realized that i could delete all unwanted entries in the mysql databaseb by using a select and delete command
i want to retain only those seq1 entries whose stop_id is less than or equal to 1000000( ie from 0 to 1000000 )

I want to delete all other sequences from seq2 to 13 and also other entries having name VCC and QAC


Code:
id start_id stop_id
seq1 3333 66663
seq1 213267 723560
seq1 900000 1000000
seq1 12348965 19968965
seq2 2333 5623
seq1 2033333 2279800
seq3 213267 723560
seq2 900000 1000000
QAC 203333 229800
seq1 4532113 7633115
VCC 33333 3421111

I want only seq1 in the database having stop id<=1000000 .

required o/p looks like :

Code:
seq1 3333 66663
seq1 213267 723560
seq1 900000 1000000

Is there a way to delete all entries other than that required?

---------- Post updated at 07:42 PM ---------- Previous update was at 07:24 PM ----------

Also another question is to reduce the file size. Is there any command to check the count size of a file.

I am asking this because I have to retain the first 100Mb of data in seq1 and then deleting the remaining bits in that file.

What command should I use to retain the first 100 mb of file and delete the remaining bits using vi or awk?

Sorry for so many posts .Thanks ALL for your help

globus-gram-audit

GLOBUS-GRAM-AUDIT(8)						  GRAM5 Commands					      GLOBUS-GRAM-AUDIT(8)

NAME

       globus-gram-audit - Load GRAM4 and GRAM5 audit records into a database

SYNOPSIS

       globus-gram-audit [--conf CONFIG_FILE] [[--create] | [--update=OLD-VERSION]] [--check] [--delete] [--audit-directory AUDITDIR] [--quiet]

DESCRIPTION

       The globus-gram-audit program loads audit records to an SQL-based database. It reads $GLOBUS_LOCATION/etc/globus-job-manager.conf by
       default to determine the audit directory and then uploads all files in that directory that contain valid audit records to the database
       configured by the globus_gram_job_manager_auditing_setup_scripts package. If the upload completes successfully, the audit files will be
       removed.

       The full set of command-line options to globus-gram-audit consist of:

       --conf CONFIG_FILE
			       Use CONFIG_FILE instead of the default from the
			       configuration file for audit database
			       configuration.
       --check
			       Check whether the insertion of a record was
			       successful by querying the database after
			       inserting the records. This is used in tests.
       --delete 	       Delete audit records from the database right
			       after inserting them. This is used in tests to
			       avoid filling the databse with test records.
       --audit-directory DIR   Look for audit records in DIR, instead of looking
			       in the directory specified in the job manager
			       configuration. This is used in tests to control
			       which records are loaded to the database and then
			       deleted.
       --query SQL	       Perform the given SQL query on the audit
			       database. This uses the database information from
			       the configuration file to determine how to
			       contact the database.
       --quiet		       Reduce the amount of output for common
			       operations.

FILES

       The globus-gram-audit uses the following files (paths relative to $GLOBUS_LOCATION.

       etc/globus-gram-job-manager.conf
					  GRAM5 job manager configuration. It includes the
					  default path to the audit directory
       etc/globus-gram-audit.conf
					  Audit configuration. It includes the information
					  needed to contact the audit database.
