-------------------------------------------
*Cat command behaviour in Linux:*
linux222:/home/hadoop/bin # cat test.*
content in test file
linux222:/home/hadoop/bin # echo $?
0
linux222:/home/hadoop/bin # cat test.* nonexist*
content in test file
cat: nonexist*: No such file or directory
linux222:/home/hadoop/bin # echo $?
1
linux222:/home/hadoop/bin # cat nonexist*
cat: nonexist*: No such file or directory
linux222:/home/hadoop/bin # echo $?
1
linux222:/home/hadoop/bin #
Here the issue in our filesystem, when we give nonexist path with *, we will
not get any error message on console. In this case we will get globstatuslength
will be zero.
After handling the above condition (globstatuslength == 0 ) we can get that
message on non matching directory with *.
> rmr command is not displaying any error message when a path contains wildcard
> characters and does not exist.

> When we give invalid directory path then it will show error message on the
> console. But if we provide the wildcard expression in invalid directory path
> then it will not show any error message even there is no pattern match for
> that path.
