Joins two files in similar style as GNU "join", but
with extra convenience of allowing unsorted inputs and
auto-detection of delimiters and headers.
make
make test
make memtest
sudo make install PREFIX=/usr/local
# Print key and line numbers where keys "ID" and "COL_ID" match.
# Auto detects column delimiters.
ezjoin -k ID,COL_ID -o key,1.line,2.line in1 in2 out
# Specify output comma delimiter and output columns with field
# names "NAME" and "TIME".
ezjoin -k ID,ID -o 1.NAME,2.TIME -O "," in1 in2 out
# When input files don't have headers, use column numbers for key.
# Here, we use the first column in file #1, and third in file #2.
# Also print "missing" columns when key in first is missing in second.
ezjoin -k 1,3 -o key,2.1 -m missing in1 in2 out
# Specify input file delimiters: first uses space, second uses comma.
ezjoin -k 1,1 -o key,1.line,2.line -d " ," in1 in2 out
# Ouput with header, re-using field names from each file.
# "key" will use the first file's field name for -k column.
ezjoin -k 1,1 -o key,1.NAME,2.ADDRESS in1 in2 out
# Suppress output header.
ezjoin -k 1,1 -o key,1.NAME,2.2 -n in1 in2 out
# Output custom header, regardless if inputs have headers.
# Input headers will be auto suppressed.
ezjoin -k 1,1 -o key,1.2,2.2 -h "ID NAME ADDRESS" in1 in2 out
ezjoin -- Join two files with column keys.
USAGE: ezjoin [OPTIONS] in1 in2 out
OPTIONS:
-D, --debug Print detailed messages for debugging.
-d, --delimiters ARG Force column delimiters for both files, such as -d
',;' will specify comma for the first file, and
semi-colon for the second file. By default,
delimiters are auto-detected in the first lines in
this order '|; , '.
-H, --hasheader If input has a header. This is autodetected if any
output column for the first file uses a field name
(instead of a digit). If only column digits are
given, and you want a custom header with -h, then
this can suppress the original header.
-h, --header ARG Custom header to output as first line.
-k, --keys ARG1[,ARGn] Column keys for both files, such as -k 1,NAME.
Defaults to first columns for both files. Column
numbers start with 1.
-m, --missing ARG1[,ARGn] What to print for missing key-values in second
file. Default is to suppress missing lookups.
-n, --noheader Suppress header output.
-O, --outdelim ARG Output delimiter. Default is space.
-o, --output ARG1[,ARGn] Columns to output, such as
-o 1.1,2.NAME,key,2.line.
A file is denoted by 1 or 2, followed by a period
and a column name or number. Column numbers start
with 1. 'key' will print the key value. X.line
will print the 1-based line number for file number
X.
-v, --version Display version info.
--help ARG Display usage instructions.
There is a choice of three different layouts for
description alignment. Your choice can be any one
of the following to suit your style:
0 - align (default)
1 - interleave
2 - stagger
