Hi,
I want to draw xgraph for my wireless simulation in AODV protocol. For that i used the following code. But in that command the column file is not working and it shows some error as " column 1: unknown file or directory column 10: unknown file or directory" when i try to execute that. Anyone is having the correct column seperator code for this. Plz guide me to get the column seperation properly... The command i have used is: cat out.tr | grep " 2 3 cbr " | grep ^r | column 1 10 | awk '{dif = $2 - old2; if(dif==0) dif = 1; if(dif > 0) {printf("%d\t%f\n", $2, ($1 - old1) / dif); old1 = $1; old2 = $2}}' > jitter.txt In this code the 2 grep and the awk commands are working fine but not the column 1 10. Plz help me... when i run this it shows column 1: unknown file or directory column 10: unknown file or directory Thank you, G.Prabhu ----------------------------------------- This email was sent using TCEMail Service.
