I have two files which contain data from two different transactions in the same format:
<Name> - <Count>
My goal is to end up with data in this format after combining the two:
<Name> - <Count1> - <Count2>

Thanks... (3 Replies)

join
JOIN(1) FSF JOIN(1) NAME
join - join lines of two files on a common field SYNOPSIS
join [OPTION]... FILE1 FILE2 DESCRIPTION
For each pair of input lines with identical join fields, write a line to standard output. The default join field is the first, delimited by whitespace. When FILE1 or FILE2 (not both) is -, read standard input. -a SIDE print unpairable lines coming from file SIDE -e EMPTY replace missing input fields with EMPTY -i, --ignore-case ignore differences in case when comparing fields -j FIELD (obsolescent) equivalent to `-1 FIELD -2 FIELD' -j1 FIELD (obsolescent) equivalent to `-1 FIELD' -j2 FIELD (obsolescent) equivalent to `-2 FIELD' -o FORMAT obey FORMAT while constructing output line -t CHAR use CHAR as input and output field separator -v SIDE like -a SIDE, but suppress joined output lines -1 FIELD join on this FIELD of file 1 -2 FIELD join on this FIELD of file 2 --help display this help and exit --version output version information and exit Unless -t CHAR is given, leading blanks separate fields and are ignored, else fields are separated by CHAR. Any FIELD is a field number counted from 1. FORMAT is one or more comma or blank separated specifications, each being `SIDE.FIELD' or `0'. Default FORMAT outputs the join field, the remaining fields from FILE1, the remaining fields from FILE2, all separated by CHAR. AUTHOR
