help in bc
hi,

the following piece of code gives syntax error
vernum is got as a string value, and to convert it to floating point number, i am using

verno=$(echo "$vernum" + 0.0 | bc )

it gives the error as syntax error on line 1

can somebody explain?

thanks,
kavitha

Not sure - what shell are you using, is the code you posted the first line of the script (or the only line)?

Try verno=`echo "$vernum" + 0.0 | bc`
