request cannot be processed again

[dave.t]

Ok this thing really is strange
I put the # symbol infront of almost all the lines except the echo statements. It still did not work.
I renamed the file to Agbpvr.cgi and it displayed the echo. Yes! But when I tried to run the same thing a second time Request Cannot Be Processed.
I renamed the file again to Bgbpvr.cgi and it worked one time only.
What is going on!

caution, as when i move the 'then' to next line, mine doesn't work anymore...

that's just what i said, too. you must NOT put the "then" into the next line. has to be:

if [ -f /etc/mvpmc/mvpmcx2 ] then
...
else
...
fi

[dave.t]

I got it
Very strange thing. I use edit pad lite
I have a few set ups as I have 3 popcorns. After playing around with different cgi files, i thought i would copy the gbpvr.cgi file from one of the working popcorns. Again this did not work. I renamed this file to 1gbpvr.cgi and changed the index.htm that called it and it worked.
Does something keep record of bad files with attached names it seems silly that it wont work as gbpvr.cgi but will work if I rename it to 1gbpvr.cgi
Very strange

Dave, this begins to ring old bells with me.
I had a script that worked for ages and was tar'd up on the PCH drive.
I had a play with it and it stopped working with the usual unhelpful error msg.
I untar'd the backup and it was the same.
So to play round I copied it to a test directory and all of a sudden it worked, but the original still didn't work.
Renaming the cgi files or the directory seemed to get things working - but for the life of me I don't know why!

that's just what i said, too. you must NOT put the "then" into the next line. has to be:

if [ -f /etc/mvpmc/mvpmcx2 ] then
...
else
...
fi

Funny, as my working script has the 'then' on its own line.

[pBS]

mine too....sorry, was a typo on my part...i meant when i *don't* move it onto next line, it doesn't work..

if [ -f /etc/mvpmc/mvpmcx2 ]
then
echo "Already Connected...........";
else

is how i've had it and when changed it wouldn't work...
it's a quirk of the syabas linux flavor as i tried every possible iteration to find out what actually worked..but that may change with firmware updates...
i *think* it can stay on same line only if whole 'if' statement is on one line..

[Turas]

hmm. that's strange indeed.
but you're right that the syntax is depending on the linux-flavor.

===
On http://steve-parker.org/sh/test.shtml (tutorial about Bourne and the Bourne Again shells) I found:

Also, be aware of the syntax - the "if [ ... ]" and the "then" commands must be on different lines. Alternatively, the semicolon ";" can seperate them:

if [ ... ]; then
# do something
fi
===

so if pch is using a bourne shell then obviously i'm wrong. which is strange indeed since "then" on the same line does work for me.
(or so i thought ... will have to doublecheck this again )

[Turas]

so.... sorry for adding some confusion.
just checked my gbpvr.cgi and you (and the tutorial ) are completely right, it has to be:

if [ -f /etc/mvpmc/mvpmcx2 ]
then
...
else
...
fi

otherwise you'll get a syntax error:

.../opt/sybhttpd/localhost.drives/HARD_DISK/_GB-PVR/gbpvr.cgi: line 14: syntax error: "else" unexpected (expecting "then")

sorry again for remembering it the wrong way round.

Mine works fine like this:

if [[ <boolean expr> ]]; then

<stuff>

fi

Maybe the A100's use a different shell than A110's?

[trummel]

The key there is the semicolon. It tells the linux shell that what follows is a new command. you could probably do this:-
if [ -f /etc/mvpmc/mvpmcx2 ];then;...;else;...;fi
although I wouldn't recommend it.

I use a similiar thing all of the time to test changes to my iptables firewall on a remote system. If I cock up, it only locks me out for 10 seconds.

service iptables start; sleep 10; service iptables stop
