acut: extract columns from the input files
(fields from line-based records)

Parameters:
-sep {c}: specify column separator character. If the input file contains lines
  like this: 'one,two,three...' you have to use '-sep ,'.
  If the separator is the '|' character, you have to use the 'pipe' symbol, in
  order to avoid command-line misinterpretations.
  The default value is the , (comma)
-os {c}: the output separator (that separates the extracted columns)
  The default value is the space
-c[ols] {c}: specify the columns. The valid expressions can select ranges
  (see example)
-colsizes, -cs: specify the output field withs (padded with spaces)

Examples:
afind *.csv | acut -sep pipe -c 2,3 -cs 5,5 -
  -> select the 2nd and 3rd fields. Possible output: '  123,   34'

afind *.csv | acut -sep pipe -c 0-5,10-20
  -> extract the columns between [0 - 5] and [10 - 20]
