help with bash variables?

[cannibalbob]

I need a variable to = 001 NOT 1... so when i use N = `expr 001 + 1` it results as 002 NOT 2...
any ideas?
:-?

You want to take 001 logical NOT 1? That's 110... you need to give more information, I have no clue what you're even trying to attempt.

[cannibalbob]

no... not logic. like this:

N=001
M=N+1

now M = 2 rather than 002...

Few ways you can do it:a=1
b=`expr $a + 1`If you want to be restricted to bash and most ksh shells, you can also say:a=1
b=$((a+1))
