Hi,That should work, unless you write a script and expect the variable to
In a ksh script I would like to assign a string back onto itself
while concatenating another string to it... something like this:
optString="$optString$newString"
I have a string variable: $optString that has the value "r"
I then get another string variable: $newString that has a value of "o"
I would like to end up with optString having a value of "ro"
As you might guess (or know outright! :-) my idea doesn't work. At
the end $optString still equals "r", not "ro". Can someone help me out
with something that works. (I have tried sed and awk as well, but
likely as not, I am not getting the syntax correct... just to let you
know I tried and am now pulling my hair out.)
be changed after the script has ended. In that case, you need to use
the "." command.
