Replace 1st field leave all others alone

[segment]

Hey all (reposting this). I have 4500+ files all close to being the same they're all 27 lines long. I'm trying to do an inplace edit for one variable but I can't seem to finesse it...

I have the following line inside every file

238 INVITE sip:$user@$server SIP/2.0\r

The number 238 is always changing and I need to remove those numbers altogether to leave:

INVITE sip:$user@$server SIP/2.0\r

Most of the changes I've made using awk, sed and perl (perl -pi -e 's/something/something else/g') but I can't find a way around this one... Remember the numbers change so in on instance it may be:

238 INVITE sip:$user@$server SIP/2.0\r

The next it may be:

1444 INVITE sip:$user@$server SIP/2.0\r

Any thoughts in this? Bear in mind, I will be passing $onevariable $twovariable (variables with $ signs). I tried to do it in one shot with awk and sed but it didn't work you would think sed 's/$/bar/g' would place bar at the end of each line but it did the opposite placed it in the beginning...

Here is one message:

No need to worry about $server $user $cseq those fields I've taken care of. This is nothing more than an example of what I need.... Reason for posting the entire text is because neither awk nor sed have worked for me... For edits on certain fields I've had success with perl (perl -pi -e 's/foo/bar/g') but I'm on a brainfart figuring out how to remove that 1st field...

perl -e 'print $i=pack(c5,(40*2),sqrt(7600),(unpack(c,Q)-3+1+3+3-7),oct(104),10,oct(101));'

something like this for starters:

sed 's#^\([0-9][0-9]*\) INVITE\(.*\)#INVITE\2#' myFile.txt

vlad
+----------------------------+
| #include<disclaimer.h> |
+----------------------------+

or being politically correct:

nawk '$1 ~/^[0-9][0-9]*/ && $2 == "INVITE" {$1=""; sub(/^ */, "")}1' myFile.txt
