command for converting string to integer

esham · #1 (**permalink**) 08-04-2005

Hi ...

I am trying to calculate the time needed for a command to execute..

but the resulting value is getting as string..

Quote:

(time -p cp /home/esham/speedtemp3 /home/ ) 2>file ; grep sys file | cut -d" " -f 2

so i am not able to use "expr " command..

please help me to convert the value to integer so that i can proceed with my script..

Regards

esham

Use bc

Say TIME=0.02

Code:

echo $TIME+1 | bc -l
