Hi,
The following cat command just hangs and is not responsive to ctrl-C.
Is it a bug? Thanks.
$ help cat
cat: cat [-] [file ...]
Display files.
Read each FILE and display it on the standard output. If any
FILE is `-' or if no FILE argument is given, the standard input
is read.
$ cat .
$ cat .
cat: .: Is a directory
What is the output of "type cat"?
$ type -a cat
cat is /bin/cat
