actually I found a better way playing around

IFS=3D"|"
read X Y Z < file_name

The file contains a list of records in which the "|" deliminates the various fields. So your method would not be best in this case. I also need to grep a particular record, for my purposes I will just put that in a temp file and use that. This is better than multiple lines of code which all grep the same line from the file and just awk a different field.

think the OS might be linux and that is the issue =20

It is a stupid way to set multiple variables from a deliminated list. Smart way would be this:

$ let A=3D2;
$ let B=3D3
$ let C=3D$A*$B
$ echo $C

6
$ echo $SHELL
/bin/ksh
$
