NAME

dbfilestripcomments - remove comments from a fsdb file

SYNOPSIS

dbfilestripcomments [-h]

DESCRIPTION

Remove any comments in a file, including the header. This makes the file unreadable by other Fsdb utilities, but perhaps more readable by humans.

With the -h option, leave the header.

OPTIONS

-h or --header

Retain the header.

This module also supports the standard fsdb options:

-d

Enable debugging output.

-i or --input InputSource

Read from InputSource, typically a file name, or - for standard input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.

-o or --output OutputDestination

Write to OutputDestination, typically a file name, or - for standard output, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.

--autorun or --noautorun

By default, programs process automatically, but Fsdb::Filter objects in Perl do not run until you invoke the run() method. The --(no)autorun option controls that behavior within Perl.

--help

Show help.

--man

Show full manual.
