Hello, bug-coreutils,
In coreutils-6.7/configure, I read:
# When cross-compiling, there is no way to tell whether // is specia
l
# short of a list of hosts. However, the only known hosts to date
# that have a distinct // are Apollo DomainOS (too old to port to)
# and Cygwin. If anyone knows of another system for which // has
# special semantics and is distinct from /, please report it to
# <[email protected]>.
OK. z/OS (IBM mainframe OS):
[EMAIL PROTECTED]:133$ uname -a
OS/390 MVS3 17.00 03 2066
... is entirely idiosyncratic. '/' and '//' are treated as identical
by most utilities and system calls:
[EMAIL PROTECTED]:134$ ls -di / //
3 / 3 //
However, fopen(), almost uniquely, and utilities that exploit it
treat them as distinct:
[EMAIL PROTECTED]:148$ wc /etc/profile //etc/profile ///etc/profile
244 1127 10166 /etc/profile
wc: file "//etc/profile": EDC5047I An invalid file name was specified as a
function parameter.
244 1127 10166 ///etc/profile
488 2254 20332 total
so, one should be cautious using //*. POSIX advises avoiding the
construct, and using ///* to be safe.
Just thought you'd like to know,
gil
