Synopsis

       getcol [-amv][-n num][-r lines][-s num] filename [column number range]

Description

       Extract specified columns from an ASCII table file

Options

       filename
              Name  of  a ASCII table file.  At least one of these must be present for any values
              to be printed.  If it is stdin or STDIN, an ASCII table  is  expected  as  standard
              input.  If there is no input file, standard input is assumed.

       @filename
              Name  of  a  file  containing a list of ASCII table files.  If this is present, any
              other file names on the command line will be ignored.

       field range
              Print value of these columns for the number of lines of the table specified by  the
              -n  argument  after the skippiing the number of lines specified by the -s argument.
              A value of 0 causes the entire input line to be printed.

       -a     Sum all numeric columns selected, printing  the  sum  on  the  line  following  the
              result.  Columns with no sum are filled with ___.  (Added in version 2.6.9)

       -b     Input is bar-separate table file

       -c     Add count of number of lines in each column at end

       -d <number>
              Number of decimal places in f.p. output

       -e     Compute medians of selected columns

       -f     Print range of values in selected columns

       -h     Print Starbase tab table header

       -i     Input is tab-separate table file

       -k     Print number of columns on first line

       -l <number>
              Number of lines to add to each line

       -m     Compute  the  means  of all numeric columns selected, printing the mean on the line
              following the result (or the line following the sum if -a is used).   Columns  with
              no mean are filled with ___.  (Added in version 2.6.9)

       -n num Print  selected  columns  for this many lines.  If not specified, all lines will be
              read after the number of lines specified by -s have been skipped.

       -o     OR conditions insted of ANDing them

       -p     Print only sum, mmean, sigma, median, or range, not entries

       -r @listfile
              -r line range Print columns from the lines specified as either  the  first  nonzero
              number on each line of the file listfile or the comma- and hyphen- delimited range;
              i.e. 1-5,10-12 will print values from lines 1, 2, 3, 4, 5, 10, 11, and 12.   (added
              in version 2.6.12)

       -s num Skip  this  many  line before starting to print values.  If not specified, no lines
              will be skipped.

       -t     Starbase (tab-separated) table output

       -v     Print more information about process.
