True.  I was trying to get too literal in translating "mimic", here. 
And if I had tried it, I would have seen error messages like "file not
found" for attempts to create a name like "*".

When I tried to make an illegal name in Explorer, it added ":", "/" and
""" (that is the double quote itself), to your list.

I'm not so sure the reasons are "obvious", though.  It is certainly not
the same reason that there are "similar problems" for UNIX.  As I
remember, the processing method used by DOS is to handle the wild card
interpretation via a "system/function call", so wild cards are handled
outside of the specific application.  An application wanting wild card
processing would need to use the supplied API.  I'm not so sure here
about exact names, but the sequence was to prepare to read names
specified by wild cards, call a "get first matching name" function, then
a "get next matching name" function and continue the get next until a no
match condition was returned.  If the application did not use the API,
the name with wild card characters would be taken literally by it, so
the underlying system needed to protect itself, by checking for and not
allowing invalid characters.

This is not the case on UNIX.  Wild card processing is done at the
application level, by the shell (and others, such as 'find').  If I
should want to, I could write a shell that uses a completely different
set of characters (or none at all), and have it co-exist with a
"standard" shell on any UNIX system available.

This concept also applies to the I/O re-direction symbols you mentioned
in your list.

To further "round out this discussion": What Bob says is true of UNIX but not
Win32.  Win32 does have other characters that it doesn't like in the filenames.
 I don't remember off the top of my head what they are, though.

Spaces in filenames is absolutely _not_ a good feature.

Also in bash, you can use what is know as "Tab Completion".  E.G.:

cd Inst<tab>

this will complete the file name for you.  This will complete the filename for
you.  It will ring the bell if there is ambiguity.  CAUTION: Don't hit the
<tab>  as the first character of the command.

Windows/Cygwin directory name stuff

[Paul Bailey]

Hi.

On my Win98 machine, I have a sub-dir called "Installer Programs".  (I also
have other directory names, and file names, with spaces in them.)

I installed Cygwin, which went OK.  I was copying and moving files, and
cd'ing throughout the filesystem.  No problems.  That is, until this:

cd Installer Programs

It wouldn't let me.  I tried

cd InstallerPrograms
cd Installer_Programs
cd Installer-Programs

Nothing doing.  Eventually I got there through:

cd Installer*

Fortunately I only have the one directory starting with the word
"Installer".

I searched throught the Web for some kind of information on spaces in Unix
filenames.  What little turned up was succinct one-liners, to the tune of
"Don't use white space in filenames."  Good advice for a Unix-only box, but
I *already* have the directories and files named as they are!

Is there some mechanism to navigate in bash through a filesystem where
directories have spaces in their names?  (I mean, I know Unix sees separate
words after a command as an argument list, but that doesn't apply in the
case of "cd" since I don't think you can cd into two separate directories
simultaneously, in the same shell, at the same time.)



Regards,


Paul Bailey.

You see, the shell does exactly what it should do: interpret the command
line, dealing with wildcards and separating arguments to commands. If a
particular command cannot handle multiple arguments (e.g. 'cd'), it's not
the shell's business. If there's an error with the parsing of the command
line, the shell complains; if not, it's the command that complains.

As for the filenames with spaces on it, you can have them on UNIX (and,
therefore, cygwin) too; you just have to tell the shell not to interpret
them, so that they are treated literally as part of the arguments. You do
this by prefixing them with a backslash ('\') or by putting quotes (single
or double) around the names of which they are part of. BTW: this is valid
for other special chars as well (*, [, ], {, } etc.).

HTH,

To round out this discussion, there is ONLY ONE character that UNIX (the
kernel) and therefor cygwin (the DLL) really cares about as "special"
and that is the forward slash (/).  This is the delimiter in a path
between the various names.  You _cannot_ have a name that contains a
literal forward slash.  Otherwise, any character is legal.

The interpretation of other characters, as special or not, depends on
the application being used, as mentioned in other posts to this
discussion.

them, so that they are treated literally as part of the arguments. You do
this by prefixing them with a backslash ('\') or by putting quotes (single
or double) around the names of which they are part of. BTW: this is valid
for other special chars as well (*, [, ], {, } etc.).

HTH,

Andre

Re: Windows/Cygwin directory name stuff

You're not directly interacting with 'Unix', you're interacting with
a shell program, which has it's own set of rules for interpreting
the commands you enter.  Commands such as 'cd' don't process
the command line, they are invoked by the shell (thought in some
cases, commands may be 'built-in' code included in the shell for
performance reasons, but still the shell processes the command
line before the args are passed to the command).

Try:  cd 'Installer programs'

Windows/Cygwin directory name stuff

[Paul Bailey]

Hi.

On my Win98 machine, I have a sub-dir called "Installer Programs".  (I also
have other directory names, and file names, with spaces in them.)

I installed Cygwin, which went OK.  I was copying and moving files, and
cd'ing throughout the filesystem.  No problems.  That is, until this:

cd Installer Programs

It wouldn't let me.  I tried

cd InstallerPrograms
cd Installer_Programs
cd Installer-Programs

Nothing doing.  Eventually I got there through:

cd Installer*

Fortunately I only have the one directory starting with the word
"Installer".

I searched throught the Web for some kind of information on spaces in Unix
filenames.  What little turned up was succinct one-liners, to the tune of
"Don't use white space in filenames."  Good advice for a Unix-only box, but
I *already* have the directories and files named as they are!

Is there some mechanism to navigate in bash through a filesystem where
directories have spaces in their names?  (I mean, I know Unix sees separate
words after a command as an argument list, but that doesn't apply in the
case of "cd" since I don't think you can cd into two separate directories
simultaneously, in the same shell, at the same time.)



Regards,


Paul Bailey.
