Shell Programming and Scripting

My script has the following for loop in it.

foreach id (CLKM4 DGTM4 GNNM4)

eval echo $id \$${id}sf \$${id}sfk

end


so "id" is a variable defined in the loop, and "idsf" and "idsfk" are variables defined in another part of the script, they return values of 0 or more. The problem i'm having is putting spaces in between the returned values. It seems that eval doesn't recognize spaces like " ", Is their a way I can't echo these same variables w/o using eval.

This works for me, if I understand your requirements correctly....

Consider the following:

Code:

> set CLKM4sf="one"
> set CLKM4sfk="also_one"
> set DGTM4sf="two"
> set DGTM4sfk="also_two"
> set GNNM4sf="three"
> set GNNM4sfk="also_three"
> foreach id ( CLKM4 DGTM4 GNNM4 )
foreach?   eval echo $id \$${id}sf \$${id}sfk
foreach? end
CLKM4 one also_one
DGTM4 two also_two
GNNM4 three also_three
>

I assume that that is your desired output?

If it doesn't work like this for you, please post your OS version and shell version, this was tested on

Code:

> tcsh --version
tcsh 6.13.00 (Astron) 2004-05-19 (i386-intel-OpenBSD) options 8b,nls,al,kan,sm,rh,nd,color,dspm,filec
> uname -a
OpenBSD somehost 3.8 GENERIC#0 i386

Well I'm not having a problem displaying the data. I just need there to be spaces in between the last two fields. My loop works fine.
