| 7 | mount: The mount command is only used to display all mount points. The mount
|
|---|
| 8 | points for the very important are automounted. Nothing is stored in the Win32
|
|---|
| 9 | registry database. If you wish to add other mount points, ones that aren't
|
|---|
| 10 | auto mounted, then you may do so in the /etc/fstab file. i
|
|---|
| 11 |
|
|---|
| 12 | ROOTPATH "/": The "/" auto mount point is currently a reference to the parent
|
|---|
| 13 | directory of the directory containing the msys-1.0.dll file.
|
|---|
| 14 | <strikeout>In later releases
|
|---|
| 15 | the / will be a reference to a pseudo device that points to the mount points.
|
|---|
| 16 | I.E. in a later release it is planned that `ls /' will list the mount points.
|
|---|
| 17 | </strikeout> I plan to do something but it won't be as previously stated.
|
|---|
| 18 |
|
|---|
| 19 | /bin: The /bin auto mount point is a reference to the directory containing the
|
|---|
| 20 | msys-1.0.dll file. I.E. if the path to msys-1.0.dll is
|
|---|
| 21 | C:\msys\1.0\bin\msys-1.0.dll then /bin resolves to C:\msys\1.0\bin.
|
|---|
| 22 |
|
|---|
| 23 | /tmp: The /tmp auto mount point is a reference to the directory that is
|
|---|
| 24 | referenced by the Win32 TMP environment variable. I.E. if the win32 TMP
|
|---|
| 25 | environment variable value is C:\TEMP then the /tmp mount point resolves to
|
|---|
| 26 | C:\TEMP.
|
|---|
| 27 |
|
|---|
| 28 | /usr: The /usr auto mount point is a reference to the parent directory of the
|
|---|
| 29 | directory containing the msys-1.0.dll file. I.E. if the path to msys-1.0.dll
|
|---|
| 30 | is C:\msys\1.0\bin\msys-1.0.dll then the /usr mount point resolves to
|
|---|
| 31 | C:\msys\1.0.
|
|---|
| 32 |
|
|---|
| 33 | /cygdrive: There is no such item. All devices and mapped shares are auto
|
|---|
| 34 | mounted with the device letter as the mount point. E.G.: the C:\ drive is
|
|---|
| 35 | referenced as /c.
|
|---|
| 36 |
|
|---|
| 37 | /etc/fstab: If this file exists then it is read for user specified mount
|
|---|
| 38 | points. The form of the record is [PHYSICAL PATH][WHITE SPACE][MOUNT POINT]
|
|---|
| 39 | where [WHITE SPACE] is one or more spaces and/or tabs.
|
|---|
| 40 |
|
|---|
| 41 | binary vs text: File processing mode is set to binary. This is not changeable.
|
|---|
| 42 | I had originally planned to set this to text mode processing but ran into
|
|---|
| 43 | various problems of which volumes have been written in the Cygwin archives.
|
|---|
| 44 | For release 1.0 of MSYS this means that you cannot have \r\n line endings on
|
|---|
| 45 | text files. In a future release it is planned to "Do The Right Thing" and
|
|---|
| 46 | predetermine the type of file being opened and set text or binary processing
|
|---|
| 47 | as appropriate for reading files. Or, predetermine the type of file and as the
|
|---|
| 48 | file is being read remove the \r from the end of the line.
|
|---|
| 49 |
|
|---|
| 50 | uname -s: The default system name is returned as MSYS_NT-4.0, if you're on
|
|---|
| 51 | NT 4.0. However you could export MSYSTEM=MINGW32 as change the returned value
|
|---|
| 52 | for `uname -s' to MINGW32_NT-4.0. This is done to aid the use of MSYS with
|
|---|
| 53 | MinGW and configuration scripts will determine that it is a MINGW32 build
|
|---|
| 54 | system.
|
|---|
| 55 |
|
|---|
| 56 | --added in version 1.0.2--
|
|---|
| 57 | /bin and /usr/bin: These are currently reserved for MSYS programs only (MSYS
|
|---|
| 58 | programs are progrms that depend on the msys-1.0.dll file). It will be unlikely
|
|---|
| 59 | that non-MSYS programs will execute properly if they exist in /bin and /usr/bin.
|
|---|
| 60 |
|
|---|
| 61 | POSIX paths in arguments: POSIX paths passed as arguments on the command line
|
|---|
| 62 | are now converted to WIN32 paths. This is only true for programs that don't
|
|---|
| 63 | exist in the /bin and /usr/bin paths. POSIX paths are determined by i) a '/'
|
|---|
| 64 | character in the argument and ii) the argument must not be two characters long.
|
|---|
| 65 | The two character filter is done so that WIN32 parameters of the type /x can be
|
|---|
| 66 | passed to the WIN32 program. This allows you to do `write /p /mydocuments/abc'
|
|---|
| 67 | and the write.exe program found in the c:\WINNT\System32 directory on my
|
|---|
| 68 | system can print to the printer on lpt1 the c:\msys\1.0\mydocments\abc file.
|
|---|
| 69 |
|
|---|
| 70 | --added in version 1.0.3--
|
|---|
| 71 | More robust checking for filesystem paths on arguments.
|
|---|
| 72 |
|
|---|
| 73 | --added in version 1.0.4--
|
|---|
| 74 | Symlink resolution.
|
|---|
| 75 | diff, diff3 and head to the distribution.
|
|---|
| 76 | --removed in version 1.0.4--
|
|---|
| 77 | Requirement that the path must begin with /.
|
|---|
| 78 | bash from the distribution.
|
|---|
| 79 |
|
|---|
| 80 | --removed in version 1.0.11--
|
|---|
| 81 | Requirement that /bin and /usr/bin are reserved for MSYS programs only.
