NAME

6       dbcolneaten - pretty-print columns of Fsdb data (assuming a monospaced
7       font)
8

SYNOPSIS

10       dbcolneaten [-E] [field_settings]
11

DESCRIPTION

13       dbcolneaten arranges that the Fsdb data appears in neat columns if you
14       view it with a monospaced font.  To do this, it pads out each field
15       with spaces to line up the next field.
16
17       Field settings are of the form
18
19           field op value
20
21       OP is >=, =, or <= specifying that the width of that FIELD must be
22       more, equal, or less than that VALUE
23
24       dbcolneaten runs in O(1) memory but disk space proportional to the size
25       of data.
26

OPTIONS

28       -E or --noeoln
29           Omit padding for the last column (at the end-of-the-line).
30           (Default behavior.)
31
32       -e or --eoln
33           Do padding and include an extra field separator after the last
34           column.  (Useful if you're interactively adding a column.)
35
36       This module also supports the standard fsdb options:
37
38       -d  Enable debugging output.
39
40       -i or --input InputSource
41           Read from InputSource, typically a file name, or "-" for standard
42           input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue
43           objects.
44
45       -o or --output OutputDestination
46           Write to OutputDestination, typically a file name, or "-" for
47           standard output, or (if in Perl) a IO::Handle, Fsdb::IO or
48           Fsdb::BoundedQueue objects.
49
50       --autorun or --noautorun
51           By default, programs process automatically, but Fsdb::Filter
52           objects in Perl do not run until you invoke the run() method.  The
53           "--(no)autorun" option controls that behavior within Perl.
54
55       --help
56           Show help.
57
58       --man
59           Show full manual.
