Hi All,
In Bash script language, how do I create a variable name
from a variable?
I am trying to create a variable called "abcStatus"
x=abc
$xStatus=xyz
obviously doesn't work. What am I doing wrong?
Many thanks,

It's not really core to Scientific Linux itself, but:
For most bash cases where I've found myself wanting something like
this, I've usually wound up using "hashes" instead. The first hash,
abc, contains a list of variable names, abcstatus, abctime, abcdate,
abcowner, etc. that can then be referrenced to refer to other valures
or hashes as needed.
I agree with everything said so far, but would like to toss in a chapter
from the Advanced Bash-Scripting Guide (ABS).
The dangers are of course still present, but might give a bit better
explanation about what is going on. I actually do have scripts I use
that utilize the \$$var method.
