Hello, Tested versions: - 4.1.2(1)-release - 3.2.39(1)-release
Reproduce by: string="1/2 3=" echo ${string//[= /]} Expected result: 123 Actual result: 1/2 3= Workaround: Escape the "inner" slash with a backslash.Within a bracket expression, the slash should lose its special meaning. It looks like the construct is incorrectly parsed (because it uses slashes itself), but I may be wrong, I didn't inspect the code.
Regards, Jan
