Large file data handling issue

I have a single record large file, semicolon ';' and pipe '|' separated. I am doing a vi on the file. It is throwing an error "File to long"

I need to actually remove the last | symbol from this file.
Code:
sed -e 's/\|*$//' filename

is working fine for small files. But not working on this big file. The file size is "614077"

614077 what? 600K isn't very large at all, sed should be able to handle it fine.

Even if it's a large file, sed will still work with it, it will just take longer.

What might be a problem are really really long lines...

hmm, yes this is a 600K file and as already said it is a single record. How can i handle the file manupulation?

What exactly do you mean by "sed is not working on this big file", What messages do you get when you press enter?
Paste the first and last 100 bytes of the file.
Also try it this way:

Code:
sed 's/|$//' filename

Thanks for the reply.. but your command also didnt work.
With the small files i can see record values and the record getting trimmed off with the trailling '|'.
When I use the same command with my actual file there is nothing that is coming on screen even if I echo it into a newfile nothing with get populated in the new file.

Starting bytes
001;04.5.1;2012-10-25 08:47:41;ABCDE||3;1351169231;1351169261;;;1351169256;1351169256;1351169261;;;;;;;;;;;00:00:05;

Ending bytes.
