i need to add missing delimiters...
ladies, gents..
say i have a file that should have 10 fields... (9 delimiters)
some records have 10 fields, some have 5 some have 8, etc.. nothing consistent, but i need my file to have 9 delimiters on each line, even if its null fields..
how can i go line by line and add the correct # of delimiters if they are missing..
i have a dirty way... but looking for help on a more elegant solution...
thanks
my ugly way... works fine on small stuff.. but when you have 100's of files, ranging in size from 10 -200 fields.. its just not practical
this example... i expect 4 delimiters on each line...
(i dont need to substitute the delimiters, just used the 1's for ease of reading)
$ cat test.txt
a1b1c1
a1b
a1b1c1
cat test.txt | awk -F1 '{print $1 "|" $2 "|" $3 "|" $4}'
a|b|c|
a|b||
a|b|c|
thanks in advance..

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.
