NAME

6       dbcolrename - change the names of columns in a fsdb schema
7

SYNOPSIS

9       dbcolrename OldName1 NewName1 [OldName2 NewName2] ...
10

DESCRIPTION

12       Dbcolrename changes the names of columns in a fsdb schema, mapping
13       OldName1 to NewName1, and so on for multiple pairs of column names.
14
15       Note that it is valid to do "overlapping" renames like "dbcolrename a b
16       b a".
17

OPTIONS

19       No non-standard options.
20
21       This module also supports the standard fsdb options:
22
23       -d  Enable debugging output.
24
25       -i or --input InputSource
26           Read from InputSource, typically a file name, or "-" for standard
27           input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue
28           objects.
29
30       -o or --output OutputDestination
31           Write to OutputDestination, typically a file name, or "-" for
32           standard output, or (if in Perl) a IO::Handle, Fsdb::IO or
33           Fsdb::BoundedQueue objects.
34
35       --autorun or --noautorun
36           By default, programs process automatically, but Fsdb::Filter
37           objects in Perl do not run until you invoke the run() method.  The
38           "--(no)autorun" option controls that behavior within Perl.
39
40       --help
41           Show help.
42
43       --man
44           Show full manual.
45
