This is likely to be a dumb one.
How can I use sed to substitute string occurances having it read from an input file and write to this very same file ?
I have a file with lots of occurances of '2006', I want to change it to '2007', but I'd like these changes to be saved on the input file.

I have 1 file that has elements as follows. Also the CVR(10) and the word "SAUCE" only appear once in the file so maybe a grep command would work?

pckt
pckt(7M) STREAMS Modules pckt(7M)NAME
pckt - STREAMS Packet Mode module
SYNOPSIS
int ioctl( fd, I_PUSH, "pckt");
DESCRIPTION
pckt is a STREAMS module that may be used with a pseudo terminal to packetize certain messages. The pckt module should be pushed (see
I_PUSH on streamio(7I)) onto the master side of a pseudo terminal.
Packetizing is performed by prefixing a message with an M_PROTO message. The original message type is stored in the 1 byte data portion of
the M_PROTO message.
On the read-side, only the M_PROTO, M_PCPROTO, M_STOP, M_START, M_STOPI, M_STARTI, M_IOCTL, M_DATA, M_FLUSH, and M_READ messages are
packetized. All other message types are passed upstream unmodified.
Since all unread state information is held in the master's stream head read queue, flushing of this queue is disabled.
On the write-side, all messages are sent down unmodified.
With this module in place, all reads from the master side of the pseudo terminal should be performed with the getmsg(2) or getpmsg() func-
tion. The control part of the message contains the message type. The data part contains the actual data associated with that message type.
The onus is on the application to separate the data into its component parts.
