.IX Title "funtbl 1"
.TH funtbl 1 "April 14, 2011" "version 1.4.5" "SAORD Documentation"
.SH "NAME"
funtbl \- extract a table from Funtools ASCII output
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBfuntable\fR [\-c cols] [\-h] [\-n table] [\-p prog] [\-s sep] <iname>
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
[\s-1NB:\s0 This program has been deprecated in favor of the \s-1ASCII\s0 text processing
support in funtools. You can now perform fundisp on funtools \s-1ASCII\s0 output
files (specifying the table using bracket notation) to extract tables
and columns.]
.PP
The \fBfuntbl\fR script extracts a specified table (without the
header and comments) from a funtools \s-1ASCII\s0 output file and writes the
result to the standard output. The first non-switch argument is the
\&\s-1ASCII\s0 input file name (i.e. the saved output from funcnts, fundisp,
funhist, etc.). If no filename is specified, stdin is read. The
\&\-n switch specifies which table (starting from 1) to extract. The
default is to extract the first table. The \-c switch is a
space-delimited list of column numbers to output, e.g. \-c \*(L"1 3 5\*(R"
will extract the first three odd-numbered columns. The default is to
extract all columns. The \-s switch specifies the separator string to
put between columns. The default is a single space. The \-h switch
specifies that column names should be added in a header line before
the data is output. Without the switch, no header is prepended. The
\&\-p program switch allows you to specify an awk-like program to run
instead of the default (which is host-specific and is determined at
build time). The \-T switch will output the data in rdb format (i.e.,
with a 2\-row header of column names and dashes, and with data columns
separated by tabs). The \-help switch will print out a message
describing program usage.
.PP
For example, consider the output from the following funcnts command:
.PP

.PP
There are four tables in this output. To extract the last one, you
can execute:
.PP
.Vb 4
\& [sh] funcnts \-s snr.ev "ann 512 512 0 9 n=3" | funtbl \-n 4
\& 1 147.000 25 147.000 25
\& 2 478.000 84 625.000 109
\& 3 817.000 140 1442.000 249
.Ve
.PP
Note that the output has been re-formatted so that only a single space
separates each column, with no extraneous header or comment information.
.PP
To extract only columns 1,2, and 4 from the last example (but with a header
prepended and tabs between columns), you can execute:
.PP
.Vb 5
\& [sh] funcnts \-s snr.ev "ann 512 512 0 9 n=3" | funtbl \-c "1 2 4" \-h \-n 4 \-s "\et"
\& #reg counts sumcnts
\& 1 147.000 147.000
\& 2 478.000 625.000
\& 3 817.000 1442.000
.Ve
.PP
Of course, if the output has previously been saved in a file named
foo.out, the same result can be obtained by executing:
.PP
.Vb 5
\& [sh] funtbl \-c "1 2 4" \-h \-n 4 \-s "\et" foo.out
\& #reg counts sumcnts
\& 1 147.000 147.000
\& 2 478.000 625.000
\& 3 817.000 1442.000
