Evaluate string containing shell variable names
Hello,

I have this:

Code:
#!/usr/bin/ksh
V1=ABC
str="hello 123;${V1}"

eval "echo $str"

i get

Code:
hello 123
/script.sh ABC not found

However eval works if $str variable doesn't contain a semicolumn (eg if str="hello 123~${v1}"

running the eval statement above would produce

hello 123~ABC


How would I use eval (any other method is fine) to evaluate a string variable whose assigned value contains names of other string variables?



Thnx.
