How to insert a column to a text file in csh?

I have a cron job to open a text file and insert a VARIABLE (dynamic).
Example:

OrigFile:
A 1 B 2 C 3 D 4 041110

UpdateFile:
A 1 B 2 C 3 D 4 Date: 041110


Since it's a cron job, so the script is written in csh.


Thanks in advance.

who said that s.*y ?
cron never will use csh !
the worst you can do in scriping is: use csh.
when you need (sure) portability use bourne.

y Q: sed 's/\(.*\) \(.*\)/\1 date: \2/' infile >outfile
will do the job.
