Hi,
I need to replace, as the title says, the first letter of each line (when it's not a number) by the same letter, but capital.
For instance :
hello
Who
123pass
Would become :
Hello
Who
123pass
Is there a way with sed to do that ? Or other unix command ?
Thank you :) (7 Replies)

BEGIN(7) SQL Commands BEGIN(7)NAME
BEGIN - start a transaction block
SYNOPSIS
BEGIN [ WORK | TRANSACTION ] [ transaction_mode [, ...] ]
where transaction_mode is one of:
ISOLATION LEVEL { SERIALIZABLE | REPEATABLE READ | READ COMMITTED | READ UNCOMMITTED }
READ WRITE | READ ONLY
DESCRIPTION
BEGIN initiates a transaction block, that is, all statements after a BEGIN command will be executed in a single transaction until an
explicit COMMIT [commit(7)] or ROLLBACK [rollback(7)] is given. By default (without BEGIN), PostgreSQL executes transactions in ``autocom-
mit'' mode, that is, each statement is executed in its own transaction and a commit is implicitly performed at the end of the statement (if
execution was successful, otherwise a rollback is done).
Statements are executed more quickly in a transaction block, because transaction start/commit requires significant CPU and disk activity.
Execution of multiple statements inside a transaction is also useful to ensure consistency when making several related changes: other ses-
sions will be unable to see the intermediate states wherein not all the related updates have been done.
If the isolation level or read/write mode is specified, the new transaction has those characteristics, as if SET TRANSACTION [set_transac-
tion(7)] was executed.
PARAMETERS
WORK
TRANSACTION
Optional key words. They have no effect.
Refer to SET TRANSACTION [set_transaction(7)] for information on the meaning of the other parameters to this statement.
NOTES
START TRANSACTION [start_transaction(7)] has the same functionality as BEGIN.
Use COMMIT [commit(7)] or ROLLBACK [rollback(7)] to terminate a transaction block.
Issuing BEGIN when already inside a transaction block will provoke a warning message. The state of the transaction is not affected. To
nest transactions within a transaction block, use savepoints (see SAVEPOINT [savepoint(7)]).
For reasons of backwards compatibility, the commas between successive transaction_modes can be omitted.
EXAMPLES
To begin a transaction block:
BEGIN;
COMPATIBILITY
BEGIN is a PostgreSQL language extension. It is equivalent to the SQL-standard command START TRANSACTION [start_transaction(7)], whose ref-
erence page contains additional compatibility information.
Incidentally, the BEGIN key word is used for a different purpose in embedded SQL. You are advised to be careful about the transaction
semantics when porting database applications.
