join_data_file.pl

A program to join two or more data files and concatenate rows.

SYNOPSIS

join_data_file.pl [–options] <file1> <file2> …

Options:
-o --out <filename>       provide output file name, default file1
-z --gz                   compress output
-v --version              print version and exit
-h --help                 show extended documentation

OPTIONS

The command line flags and descriptions:

• –out <filename>

  Provide the name of the output file. If the input files were split using ‘split_data_file.pl’, then the original base name may be reconstituted. Otherwise, the user will be asked for an output file name.

• –gz

  Indicate whether the output files should be compressed with gzip. Default behavior is to preserve the compression status of the first input file.

• –version

  Print the version number.

• –help

  Display the POD documentation

DESCRIPTION

This program will join two or or more data files, essentially concatanating the files but intelligently dealing with the metadata and column headers. Checks are made to ensure that the number of columns in the subsequent files match the first file.

The program will not merge datasets from multiple files; see the program ‘merge_datasets.pl’ for that.

This program is intended as the complement to ‘split_data_files.pl’.
