ODT Column Extraction: odtcols
The odtcols utility extracts column
subsets from ODT data
The odtcols launch command is:
tclsh oommf.tcl odtcols [standard options] [-s] [-w colwidth] \
[-f format] [col ...] <infile >outfile
Commonly the -s switch is used in a first pass, to reveal the
column headers; specific column selections may then be made in a second,
- Produces a file summary instead of column extraction. Output includes
table titles, column and row counts, and the header for each specified
column. If no columns are specified, then the headers for all the
columns are listed.
- -w colwidth
- Minimum horizontal spacing to provide for each column on output.
Optional. Default value is 15.
- -f format
- C printf-style format string for each output item. Optional. Default
- col ...
- Output column selections. These may either be integers representing
the position of the column in the input data (with the first column
numbered as 1), or else arbitrary strings used for case-insensitive
glob-style matching against the column headers. The columns are
output in match order, obtained by processing the column selections
from left to right. If no columns are specified then by default all
columns are selected.
- Odtcols reads its input from stdin. Use the redirection operator
``<'' to read input from a file.
- Odtcols writes its output to stdout. Use the redirection operator
``>'' to send the output to a file.
