will remove the blank lines and will display the results in the screen.
You have to redirect the output to a new filename.
$ sed '/^$/d' filename > NEW_FILENAME

nlist_pa
nlist_pa(4) Kernel Interfaces Manual nlist_pa(4)
NAME
nlist_pa: nlist, nlist64 - structure formats for PA-RISC systems
SYNOPSIS
Remarks
The exact content of the structures defined below can be best found by examining It varies somewhat between various HP-UX implementations.
This manpage describes on PA-RISC systems. For on Integrity systems, see nlist_ia(4).
DESCRIPTION
and can be used to extract information from the symbol table in an object file (see nlist(3C)). They are basically the same tool except
can only process SOM files on a PA-RISC 32-bit system while can process SOM and ELF files on either a PA-RISC 32-bit or 64-bit system.
Since symbol tables are machine dependent (as defined in each implementation's copy of a header file, is defined to encapsulate the differ-
ences.
The nlist function, either or when used with the corresponding nlist structure, can be used to extract certain information about selected
symbols in the symbol table. The data associated with each symbol is machine specific, thus only the name and position of the field in the
function is standardized by HP-UX. The rest of the structure includes at least the value and type of the symbol. The names and meanings
of all fields not standardized will change no more than necessary.
