Re: tcsh doesn't find commands that end with .exe

I have the following problem with tcsh:

tcsh doesn't find the program if the .exe extension is given.  whoami is
only an example, this also happens to other programs.

[quetschke@Macros ~]$ which whoami
[quetschke@Macros ~]$ which whoami.exe
whoami.exe: Command not found.

That's by design.

You mean the grand design that leads earth and all its inhabitants to eternal bliss?

And if so, it seems to have a flaw:

[quetschke@Macros ~]$ which cmd.exe
[quetschke@Macros ~]$ which cmd

Care to elaborate where the difference comes from?

Why should I not be allowed to start a program with it's
real name? And why does it work sometimes?

Dunno why it prints cmd.exe but by design (minus flaws) tcsh only starts applications given w/o path if the application is in the internal hash table. The internal hash table stores the application names w/o .exe suffix.
And all lower case, (cygwin only). Try something like this:

Put progA.exe in /mytestexedir and add that to your PATH.

Start a tcsh and type "prog<TAB>"
[quetschke@Macros ~]$ prog
progA    progman

Aha progA, good try this.

[quetschke@Macros ~]$ progA
progA: Command not found.

Hmmm, try proga:

[quetschke@Macros ~]$ proga
(here will be the output of progA.exe)

Well, better don't use mixed cases.

If you need something different:
The maintainer might think about removing "strlwr(dp->d_name);"
from line 776 of sh.exec.c .

Oh and somehow tcsh's hash cannot handle directories with very many
files (i.e. /cygdrive/c/WINDOWS/system32/) therefore it doesn't seem
to hash them and does a real lookup instead. (I didn't look hard enough
at the code to really proove this, but just copy everything from
 /cygdrive/c/WINDOWS/system32/ into /mytestexedir/ and you will see
that proga progA.exe proga.exe can now be found and accessed. Just like
cmd CMD cmd.exe CMD.EXE .... )


$ ll /mytestexedir/ | wc -l
