Help! I've gone brain dead

Mark Fenton — Wed, 27 Feb 2002 20:33:37 GMT

and can't recall how to increment a variable in shell!

I want to do something like:

VAR=1
for blah blah blah
do
VAR=$VAR+1
echo $VAR > somewhere
do some other stuff
done

Mark,

To be brain dead, you have to be in management!

Hi Mark,

Another method:
VAR=`expr $VAR + 1`

Sounds like Harry and Shiju have had some of the same managers I've had! Ya'll didn't use to work at...

Well, better left unsaid!

Hi Mark:

In keeping with more-than-one-way:

# let X=X+1

Regards!

Thanks all.

Harry -- I have to apologize -- if I had thought about it, the chuckle should have been worth at least 10.

All others, thanks for breathing life back into a frazzled admin......

This forum is great.
