Keep Leading Zero 1

[vodkadrinker]

Example

>echo 08 + 01|bc -l
9

and I am after 09 is there an easy way to do this please.

 

[PHV]

One way:
printf "%02d" $(echo 08 + 01|bc -l)

Another way:
typeset -Z2 i=$(echo 08 + 01|bc -l)

Hope This Helps, PH.

Yet another way:
typeset -Z2 i=$(( 8 + 1 ))

typeset -Z2 var
var=$(echo 08 + 01|bc -l)
echo $var
09

From TFM

typeset [+HLRZfilrtux [n]] [Name[= Value]] ... Sets attributes and values for shell parameters. When invoked inside a function, a new instance of the Name parameter is created. The parameter value and type are restored when the function completes. You can specify the following flags with the typeset command:

-Z
Right-justifies and fills with leading zeros if the first nonblank character is a digit and the -L flag has not been set. If the n parameter has a nonzero value, it defines the width of the field; otherwise, it is determined by the width of the value of its first assignment.

I like the printf option as it keeps things simple.

Many thanks everyone,
