I'm impressed (though after running the code I think the then and else sections should be reversed - see below.)
I admit I'll have to spend a day with sed one of these days and I will, but just assuming all is well - and it looks like it is - what's the exit status of sed used by if here?
According to sed documentation sed returns 0 on successful completion and 1 if it encounters an invalid command, invalid syntax. The latter doesn't seem to be the case here.
In your code it looks like sed returns 0 for a valid value and 1 for an invalid one.
With tplus being (then/else reversed and echo $? added by me):
this is the output I get:
And... er... do you have a suggestion how to do it in a naked regular expression within [[ ... ]], without using sed or another program?
Say I write something like the following:
var1=1
var2=2
for int in 1 2
do
echo "\$var$int"
done
I want the output to be:
1
2
Instead I get something like:
$var1
$var2 (2 Replies)

I am having trouble parsing rpm filenames in a shell script.. I found a snippet of perl code that will perform the task but I really don't have time to rewrite the entire script in perl. I cannot for the life of me convert this code into something sed-friendly:
