In general no. A hashed file is a database table. Your question is analogous to "can we access (read field) from Oracle table?".

You can invoke dssh to execute an appropriate query in that environment.

There is an operating system level command for reading the entirety of a single record from a hashed file, the name of the command is UVread. It displays the record in raw format, for example with dates in internal format, one field per line on stdout.

If it is an absolute necessity, why dont you write the hash file to a sequential file and then try to read it using unix (vi editor) ?
