    > ps -o ucomm,pmem,nswap,inblock,oublock,pcpu
    COMMAND          %MEM NSWAP INBLK OUBLK %CPU
    csh               0.3     0    14     8  0.0
    netscape          9.6     0  8143  6848  0.0
                       ^      ^    ^     ^    ^
                       |      |    |     |    |
    how do you write ksh script to read the above values and assign them
    to variables and then use them for calculation ?
    
    -Man
    

        Maybe this small example will get you started...
