Setting value for multiple variables

[Sylvain CROUET]

Hi!

I want to initialize several variables with the same value. I try to use a for loop

for VAR in A B C ; do
$VAR=xxx
done

but I get error messages :
./myscript[21]: A=: not found

That's because you are thinking "perl"

It should be "VAR=xxx" not "$VAR=xxx"

That won't work either.

This work but it's ugly !
#!/bin/ksh
for VAR in A B C ; do
eval $VAR=xxx
done
echo $A $B $C

There must be a better way.

Cheers,

Nicolas

for V in A B C
do
export $V=xxx
done

is another way. gotta be a cleaner way.

Thanks Nicolas,

Didn't read that one correctly :)

You could use an array, if you use numerous variable.

Also, I was looking at set and typeset builtin command but I can't make anthing of it.
