Shell Programming and Scripting

Immediately following is a line of text that I wish to run through sed to have a couple things changed.

MSCT HATR/sgf-v1_1-3010-20080510-200727.dx* -> UDP 127.0.0.1

Using a script with sed ive been trying to get the letters "HATR" to be whatever I decide by using a "$1" after the script name when i start the script with no luck. I would also like to take the 4 digits that appear immediately after the "sgf-v1_1-" and alter the first digit from a 3 to a 6 and place it with a blank space after the last number in the line. So if I named this script alter and I had multple lines to ammend like the one above I would type

alter 25SEPTHATR and it would give me the following out:

MSCT 25SEPTHATR/sgf-v1_1-3010-20080510-200727.dx* -> UDP 127.0.0.1 6010
MSCT 25SEPTHATR/sgf-v1_1-3010-20080610-200727.dx* -> UDP 127.0.0.1 6010
MSCT 25SEPTHATR/sgf-v1_1-3011-20080510-200727.dx* -> UDP 127.0.0.1 6011
MSCT 25SEPTHATR/sgf-v1_1-3011-20080610-200727.dx* -> UDP 127.0.0.1 6011

Can anyone show me how Ive already done alot with sed to get the chages to this point just cant figure these last couple out?

post your script so far, and input example + output example

well - I assume this is close to what your after ....

Code:

#   echo "MSCT HATR/sgf-v 1_1-3010-20080510-200727.dx* -> UDP 127.0.0.1" | sed 's/\(.*sgf-v 1_1-\)\(.\)\(...\)\(.*\)/\1\2\3\4 6\3/g'
MSCT HATR/sgf-v 1_1-3010-20080510-200727.dx* -> UDP 127.0.0.1 6010

Another one:

Code:

#!/bin/sh

awk -F" |/" -v var=$1 '{$2=var;split($3,a,"-");$NF=$NF" "a[3]+3000}{print}' file

Save this script as alter, make it executable and start the script as follow:

Code:

./alter 25SEPTHATR

Either one worked out well I appreciate you guys providing me an answer so quickly. I posted one more question concerning sed in the Shell Programming and Scripting Forum where this one was. If you could help me with that it would complete my task at hand...thanks in advance.
