swap fields in a file

I have a file (tmp.out) with contents delimited by '|':

1|d|2|rt|
3|sfd|4|sgf|
5|sg|6|gtr|
7|s|8|sf|

I want to write only the 1st and 3rd columns to another file, but they should be swapped with each other:

2|1
4|3
6|5
8|7

Here is what I have so far:

cat tmp.out | cut -d'|' -f3,1 > eid_tmp.out

Thanks,

- CB

DH_MOVEFILES(1) 						     Debhelper							   DH_MOVEFILES(1)

NAME
dh_movefiles - move files out of debian/tmp into subpackages SYNOPSIS
dh_movefiles [debhelperoptions] [--sourcedir=dir] [-Xitem] [file...] DESCRIPTION
dh_movefiles is a debhelper program that is responsible for moving files out of debian/tmp or some other directory and into other package build directories. This may be useful if your package has a Makefile that installs everything into debian/tmp, and you need to break that up into subpackages. Note: dh_install is a much better program, and you are recommended to use it instead of dh_movefiles. FILES
debian/package.files Lists the files to be moved into a package, separated by whitespace. The filenames listed should be relative to debian/tmp/. You can also list directory names, and the whole directory will be moved. OPTIONS
--sourcedir=dir Instead of moving files out of debian/tmp (the default), this option makes it move files out of some other directory. Since the entire contents of the sourcedir is moved, specifying something like --sourcedir=/ is very unsafe, so to prevent mistakes, the sourcedir must be a relative filename; it cannot begin with a `/'. -Xitem, --exclude=item Exclude files that contain item anywhere in their filename from being installed. file ... Lists files to move. The filenames listed should be relative to debian/tmp/. You can also list directory names, and the whole directory will be moved. It is an error to list files here unless you use -p, -i, or -a to tell dh_movefiles which subpackage to put them in. NOTES
Note that files are always moved out of debian/tmp by default (even if you have instructed debhelper to use a compatibility level higher than one, which does not otherwise use debian/tmp for anything at all). The idea behind this is that the package that is being built can be told to install into debian/tmp, and then files can be moved by dh_movefiles from that directory. Any files or directories that remain are ignored, and get deleted by dh_clean later. SEE ALSO
debhelper(7) This program is a part of debhelper. AUTHOR
