Cut first column from file in Vi(Vim)

I have a parts file that looks like this:

It is an ascii text file ( *.csv ) that can go on for 1000s of lines.  I want to cut out the first column , the part number only.  It is delimited by a split bar "|".

Can I do this in Vi ( Vim) so I produce a file of the first column only like below?

EE36264
F1.5
F7-412-1
FCO26A
M1363400104
M1490300004
CA2210A4R
CL-4-BLPL-0.75-S

thanks.

are you looking for vi solution only?

for alternate:

awk -F"|" '{ print $1 }'  filename > NewFilename

:1,$ s/|.*//
:w output_file

Worked! Thank you very much.

Yes. I need a Vim solution because I am using Vim on Windows 7.

awk, cut, sed and so on can't be run on a windows box , right?

You can install cygwin and there you can use mentioned commands.
