It is not a bug but just a feature.
The command does cd but for it's OWN separate process. It does
change the current directory but for that process not for ROOT
session.
The proper way to change the current directory for the ROOT session
can be found with tutorials/rootalias.C as follows:
root\tutorials\rootalias.C:
//_______________________________________________
char *pwd()
{
return gSystem.WorkingDirectory();
}
//_______________________________________________
char *cd(char *path=0)
{
if (path)
gSystem.ChangeDirectory(path);
return pwd();
}
To load this rootalias.C "by automatic" one should adjust
".rootrc" file and put in into his "home" directory. (For 95 one has
to define the home directory himself and set HOME env variable "by
hand").
Having completed this from ROOT session one may use:
root [0] cd("c:/")
or
root [0] cd("c:\\")
to change the current directory on PC. I'd like to call your
attention that with the second "native" form of the
directory name one should apply "backslash" TWICE due C/C++ syntax.
The "right" slash will work too and it is the prefered method since
it is Ok for UNIX and for Windows as well.
Hope this helps,
Valery
