Full Discussion: Insert Columns before the last Column based on the Count of Delimiters

Try (untested):
Code:
awk -FÇ 'NF < 140 {NF+=2; $NF=$(NF-2);$(NF-2)=""}' file

This would add two columns even if there's just e.g. three of them. Is that what you want?

rcvpack

RCVPACK(1)                                                           [nmh-1.5]                                                          RCVPACK(1)

NAME

       rcvpack - append message to file

SYNOPSIS

       /usr/lib/mh/rcvpack file [-mbox] [-mmdf] [-version] [-help]

DESCRIPTION

       The rcvpack program will append a copy of the message to the file listed on its command line.

       If the -mbox switch is given (the default), then the messages are separated using mbox (uucp) style delimiters.  This is the format used by
       most mail clients (elm, mailx, etc.).

       If the -mmdf switch is given, then the messages are separated by mmdf style delimiters.  Each message in the  file  is  separated  by  four
       CTRL-A's and a newline.

       rcvpack will correctly lock and unlock the file to serialize access to the file, when running multiple copies of rcvpack .

       In general, its use is obsoleted by the file action of slocal, although it might still have occasional uses in various shell scripts.

FILES

       /etc/nmh/mts.conf          nmh mts configuration file

SEE ALSO

       rcvdist(1), rcvstore(1), rcvtty(1), slocal(1)

BUGS

       Only two return codes are meaningful, others should be.
