Scenario
$ VAR1=test
$ VAR2=testing
$ VAR3=$VAR1_$VAR2
$ echo $VAR3
testing
I expected “test_testing” as the output. Why its not working? How to output in “test_testing” format? (make $VAR1_$VAR2 work)
Does it interprets VAR3=$VAR1_$VAR2 as VAR3=$(VAR1_$VAR2) ?
try:
it interprets
VAR3=$VAR1_$VAR2as$VAR1_ + $VAR2— there is no variable named $VAR1_
