So - what did you change from post#3 to #5?


Date / time arithmetic is among the ugliest problems in IT. Try this slightly adapted version that IS NOT PREPARED to cross midnight:

Code:
for FN in 2007*.txt; do T1=${FN#*T}; T1=${T1%.*}; if (( T1 - 3000 <= T2)); then echo $OFN$'\n'$FN; fi; OFN=$FN; T2=$T1; done
2007-12-27T150000.txt
2007-12-27T153000.txt
2007-12-27T153000.txt
2007-12-28T000000.txt
2007-12-28T000000.txt
 2007-12-28T003000.txt


EDIT: seems to cross midnight, but is far from robust:



Code:
for FN in 2007*.txt; do T1=${FN#*T}; T1=${T1%.*}; if (( (240000 + 10#$T1 - 10#$T2) % 240000 <= 3000)); then echo $OFN$'\n'$FN; fi; OFN=$FN; T2=$T1; done

COMMIT 
PREPARED(7) PostgreSQL 9.2.7 Documentation COMMIT PREPARED(7) NAME
COMMIT_PREPARED - commit a transaction that was earlier prepared for two-phase commit SYNOPSIS
COMMIT PREPARED transaction_id DESCRIPTION
COMMIT PREPARED commits a transaction that is in prepared state. PARAMETERS
transaction_id The transaction identifier of the transaction that is to be committed. NOTES
To commit a prepared transaction, you must be either the same user that executed the transaction originally, or a superuser. But you do not have to be in the same session that executed the transaction. This command cannot be executed inside a transaction block. The prepared transaction is committed immediately. All currently available prepared transactions are listed in the pg_prepared_xacts system view. EXAMPLES
Commit the transaction identified by the transaction identifier foobar: COMMIT PREPARED 'foobar'; COMPATIBILITY
COMMIT PREPARED is a PostgreSQL extension. It is intended for use by external transaction management systems, some of which are covered by standards (such as X/Open XA), but the SQL side of those systems is not standardized. SEE ALSO
PREPARE TRANSACTION (PREPARE_TRANSACTION(7)), ROLLBACK PREPARED (ROLLBACK_PREPARED(7)) PostgreSQL 9.2.7 2014-02-17 COMMIT PREPARED(7)
