Problem with SED in shell script

Nagendar — Thu, 26 Dec 2002 08:51:47 GMT

Hi friends,

I have a strange problem with sed in shell scripts on HP-UX 11.0.

The scripts is like this:
sed -e "s,dummyPort,$PORT,g" < /tmp/new-httpd1.conf >/tmp/new-httpd2.conf

sed -e "s,dummysslPort,$SSL_PORT,g" < /tmp/new-httpd2.conf >/tmp/new-httpd.conf

In the above two sed functions, first sed works fine. Second one gives the following error:
"sed: Function s,dummysslPort,443 cannot be parsed"

I even tried the following:

sed -e "s/a/b" -e "s/b/c" < file1 >file2. This also gives the same error.

I even replaced -e with -n and tried. Still does not work.

Any ideas? Please help.

Thanks,
Nagendar

I had a similar problem I changed the last sed command to:

's/$/
'

and the problem went away. I have no idea if that is a reasonable way
to fix it, though.

Hi,

You mean to say replace double quotes (") with with single quotes (') ?

Yes, that works fine. But the problem is that takes the literal values. I mean you can't use a variable in that case. That is another side problem of using single quotes.

Looking forward for more solutions.

hi,

Perhaps problems are not the same ...

In the first case, what is the content of $SSL_PORT ? If it contains a ',' it could generate errors due to string evaluation before execution. Try with another separator like / or ; ...

In your second sed problem, just add a final / and it will work (you must always have a third time the fiel separator.

Regards.

Hi,

The port does not contain the ",".

Regarding the second suggetion, I have put the third file seperator too in the sed. It does not solve the problem :(

Hi, the value of one of params was messed up. Hence the unusual behaviour. Thanks for the replies.

Hi Nagendar,

Try this:

sed -e 's/dummysslPort/'$SSL_PORT'/g' < /tmp/new-httpd2.conf >/tmp/new-httpd.conf

Justo.
