Verify the data type in a file with UNIX function

I am seeking help on this UNIX function, please help. Thanks in advance.

I have a large file, named as 'MyFile'. It was tab-delmited, I am told that each record in column 1 is unique. How would I verify this with UNIX function or command?

NAME
pddump - Dump profiling data files SYNOPSIS
pddump file... OPERANDS
A data file generated by a profiled program. A valid file is identified as a "profiling data file" by the file(1) command. DESCRIPTION
The pddump command displays, on the standard output, the record definitions and data of the specified profiling data files. Each file's dump is prefixed by the line "File = file:". This is followed by the file's field-alignment option and a list containing the file's name/value attribute pairs and the file's record definitions. Then each record in the file is dumped, showing the name of the record and the name and value of each of its fields. Strings are printed within double quotes, unsigned integers are printed in hexadecimal, and signed integers and floating-point numbers are printed in decimal. Non-array data lines contain equal signs to assist in filtering. The content of the profiling data files produced by Tru64 UNIX may be expanded in future releases, but Tru64 UNIX tools will continue to support older formats. To write tools that process Tru64 UNIX profiling data files, use the pdtostd(1) command to convert the Tru64 UNIX formats to industry standard formats, where a standard format exists. Alternatively, use the libpdf.a utilities to read the profiling data files directly, skipping any new attributes, records, or fields that may appear. FILES
