To just print non-repeated lines in the file turns out to be a bit of a pain. The uniq command would do it but only if the key is on the right hand side of the line, so I've put it there.
The code sorts the file on the first column (delimited by pipes) then appends the key to the end of the line uses and uses uniq to remove line with non-repeated keys before stripping off the added key!
Looks a bit klunky - I'm sure that someone could do something more elegant

uniq
UNIQ(1) General Commands Manual UNIQ(1)NAME
uniq - report repeated lines in a file
SYNOPSIS
uniq [ -udc [ +n ] [ -n ] ] [ input [ output ] ]
DESCRIPTION
Uniq reads the input file comparing adjacent lines. In the normal case, the second and succeeding copies of repeated lines are removed;
the remainder is written on the output file. Note that repeated lines must be adjacent in order to be found; see sort(1). If the -u flag
is used, just the lines that are not repeated in the original file are output. The -d option specifies that one copy of just the repeated
lines is to be written. The normal mode output is the union of the -u and -d mode outputs.
The -c option supersedes -u and -d and generates an output report in default style but with each line preceded by a count of the number of
times it occurred.
The n arguments specify skipping an initial portion of each line in the comparison:
-n The first n fields together with any blanks before each are ignored. A field is defined as a string of non-space, non-tab charac-
ters separated by tabs and spaces from its neighbors.
+n The first n characters are ignored. Fields are skipped before characters.
