Hi.

I'll skip the usual posting of the entire demonstration script.
Code:
Input:
a  b  c  d  e  f  g  h  i
1,1 1,2 1,3 1,4 1,5 1,6 1,7 1,8 1,9
2,1 2,2 2,3 2,4 2,5 2,6 2,7 2,8 2,9
3,1 3,2 3,3 3,4 3,5 3,6 3,7 3,8 3,9

-----
 Results for sequence "recut 1,2,1,4,6-":
a       b       a       d       f       g       h       i
1,1     1,2     1,1     1,4     1,6     1,7     1,8     1,9
2,1     2,2     2,1     2,4     2,6     2,7     2,8     2,9
3,1     3,2     3,1     3,4     3,6     3,7     3,8     3,9

OS, ker|rel, machine: Linux, 3.16.0-4-amd64, x86_64
Distribution        : Debian 8.6 (jessie)

recut - ( local: RepRev 1.1, ~/bin/recut, 2010-06-10 )

Missing textutils:

The recut command allows dash-notation, replication of fields, etc. The details for recut are:
Code:
recut   Process fields like cut, allow repetitions and re-ordering. (what)

See the webpage noted above for 80 or so similar commands.

The command csvtool can also do this:
Code:
 Results for sequence "csvtool -t " " -u " " col 1,2,1,4-5,6-":
a b a d e f g h i
1,1 1,2 1,1 1,4 1,5 1,6 1,7 1,8 1,9
2,1 2,2 2,1 2,4 2,5 2,6 2,7 2,8 2,9
3,1 3,2 3,1 3,4 3,5 3,6 3,7 3,8 3,9

Best wishes ... cheers, drl
