The following behavior confused me:
basename .a .a
.a
while I expected no output, since there is nothing in front of
`.a'. This is not a completely made up situation: I may do
basename /usr/lib/$A.a .a
and if $A is unset, I get the suffix `.a'. (This is how I noticed the
problem, since I tested for the empty string as a possible output of
the above, and not for `.a')
Is this a feature? The behavior contradicts the info documentation:
"If SUFFIX is specified and is identical to the end of NAME, it is
removed from NAME as well."
If I remove .a from "".a, I get "". Or NAME is not supposed to be ""?
But I get
A=.a echo b${A%.a}
b
I notice that Solaris's basename behaves the same as GNU's.
Thx
