Hi...need your expertise...I'm a newbie to scripting. I have a file whose numerical content, I need to multiply by 1000. The file is called crc.sdf The format of its content is as follow. (INTERCONNECT U663/Y ERRFLG (0.000082:0.000082:0.000082) (0.000082:0.000082:0.000082)) (INTERCONNECT U667/Y DOUTVALID (0.000054:0.000054:0.000054) (0.000054:0.000054:0.000054)) (INTERCONNECT DOUTREADY U524/A (0.000550:0.000550:0.000550) (0.000550:0.000550:0.000550)) Basically I need to change those numbers, 3 numbers in each parenthesis (they represent time in ns to ps). It's probably easiest to search for . then take the number and multiply it but I'm not sure exactly how to do that. Any help is greatly appreciated. Sup

Try this: #!/bin/ksh function count { output1=$(print "$2 * 1000;scale=2" | bc) output2=$(print "$3 * 1000;scale=2" | bc) output3=$(print "$4 * 1000;scale=2" | bc) print "The results are $output1 $output2 $output3" } IFS="(): " exec 3 ./data.comp while read -u3 line do case $line in *I* ) : #print $line ;; * ) count $line ;; esac done Please note: There should be a left angle bracket between the exec 3 and the ./data.comp. That is what I named your data file as. Change it as appropriate. Jerry
