Hi.
There are probably other (better) ways, but:

#!/bin/ksh

set -A ARGS $@

FILE=${ARGS[$(expr $# - 1)]}

echo $FILE

Regards.

Yes, I've tryed it and works. Tough, in the example, the script only takes the file name and echoes it. From that, doing the rest is easy.... For instance:

#!/bin/ksh

set -A ARGS $@

FILE=${ARGS[$(expr $# - 1)]}

echo $@ | sed s/$FILE// >> $FILE

well i cant use sed at the moment am not on that chapter yet.

any other way would be nice. And pls can give an explanation of the code in details

Thanks

And pls the the remaining arguments goes into the middle of the file and not the begining or end of it.

Thank u.

set -A ARGS $@ defines ARGS as an array and initializes it with the script arguments.

$@ is the list of arguments itself.

FILE=${ARGS[$(expr $# - 1)]} assigns the last argument to the FILE variable. This is the way arrays are managed on ksh

$# is the number of arguments, so

expr $# -1 is the position of the last one within the array

Is this homework or something? Have a look to rule #6 on:

My intention was to give you some hints so try first to do it for yourself, then ask the forum.

Regards.
