After reading the man more carefully, an end position should be
specified for the key:
"KEYDEF is F[.C][OPTS][,F[.C][OPTS]] for start and stop position, where
F is a field number and C a character position in the field; both are
origin 1, and the stop position defaults to the line's end."
Hence
cat junk
AA|def
A|xyz
cat junk | sort -k1,1 -t"|" # 1=start position, 1=end position
A|xyz
AA|def
It's all good now.
Ahaha. Thank you! - Cameron
