"a*" in this context is not a wildcard. It is a literal string. You need -regexm()- or -strmatch()- for the wildcard interpretation.

I have an example that fails to replace string var using wildcard in expression. I tried this and it fails... Any idea? var1 is string. 


var1 

abc
ab
d
e

replace var1="" if var1=="a*"

0 obs replaced.
