Hi all
Is there a way in awk to know that you are processing your final line of input if you do no know how many lines were in the input to begin with?
Thanks (7 Replies)

Hello,
I extracted a list of files in a directory with the command ls . However this is not my computer, so the ls functionality has been revamped so that it gives the filesizes in front like this :
This is the output of ls command : I stored the output in a file filelist

start_transaction
START TRANSACTION(7) SQL Commands START TRANSACTION(7)NAME
START TRANSACTION - start a transaction block
SYNOPSIS
START TRANSACTION [ transaction_mode [, ...] ]
where transaction_mode is one of:
ISOLATION LEVEL { SERIALIZABLE | REPEATABLE READ | READ COMMITTED | READ UNCOMMITTED }
READ WRITE | READ ONLY
DESCRIPTION
This command begins a new transaction block. If the isolation level or read/write mode is specified, the new transaction has those charac-
teristics, as if SET TRANSACTION [set_transaction(7)] was executed. This is the same as the BEGIN [begin(7)] command.
PARAMETERS
Refer to SET TRANSACTION [set_transaction(7)] for information on the meaning of the parameters to this statement.
COMPATIBILITY
In the standard, it is not necessary to issue START TRANSACTION to start a transaction block: any SQL command implicitly begins a block.
PostgreSQL's behavior can be seen as implicitly issuing a COMMIT after each command that does not follow START TRANSACTION (or BEGIN), and
it is therefore often called ``autocommit''. Other relational database systems might offer an autocommit feature as a convenience.
The SQL standard requires commas between successive transaction_modes, but for historical reasons PostgreSQL allows the commas to be omit-
ted.
See also the compatibility section of SET TRANSACTION [set_transaction(7)].
