Directory structuring

Directory structuring

[PaulAThompson]

I am very confused about the correct manner of defining directory paths under
cygwin, perl, and bash. I cannot determine the correct manner. Using the
cygwin window, I navigate to locations using 

cd /cygdrive/c/subdir

Using a bash shell to run a perl process under the shell and passing in a
directory, I must use a windows-style specification with *nix forward
slashes

c:/subdir

I have tried a number of manner of using cd within the bash shell to change
directories without any success

Is there a simple guide to the path specifications? This seems simple, but I
cannot figure out the correct specification

Within the bash shell, I have tried 

cd /cygdrive/c/subdir
cd "/cygdrive/c/subdir"
cd c:/subdir
cd "c:/subdir"

None of these work

If you're using Cygwin's Perl, then you don't need to worry about
windows-style paths.  If you must, for some reason, use the Windows-native
Perl, then check out 'man cygpath'.  It will handle the file path
conversions for you so you can stick with POSIX paths when you type.

'dir' is from the "coreutils" package which is installed by default.
Check if you have '/usr/bin/dir.exe".  If not, your installation is
incomplete.

[zac]  As far as I can reproduce all windows/terminals under cygwin using the bash. So the reason for your problem might be located somewhere else.

[zac] All of them should work! So what exactly is the reaction you get from the bash ??

Re: Directory structuring

[PaulAThompson]

I have solved this problem. Please do not reply any more.

Solution:

1) Ensure that cygwin was using a cygwin-native perl
2) Routine use of d2u to get the files to have *nix endings for lines not
windows endings
