copy and move files
|
|

| Hi, i need help.i am a quite new user of fortran. I would like to
rename a file (used as input file) and move it to another directory.
Which command can I use?
thanks

If you tell us the compiler you're using, someone will be able to
explain how to invoke system commands.

Fortran is not really suited for this type of tasks.
What you can do is one of the following:
1. Use the "system" subroutine. It is a common extension to
the standard. You can use it to run system commands:
character*100 command
write( command, '(4a)' ) 'copy ', file1, ' ', file2
call system(command)
This is a system-dependent and compiler-dependent way
of doing it though.
2. Open the old file and the new one, read the information
from the old file and write it to the new one.
This is an inefficient process, and depending on the
details (type of file, whether you want an exact copy
or can live with trailing blanks and the like) you may
be able to get what you want.
There was another thread not too long ago about the same
subject (or it ended up discussing the various options).
That will provide more details.
Regards,
Arjen

call system("copy " // trim(file1) // " " // trim(file2))
is more concise and more general, since it will work even if the file
names are long

Oops, you are right - you might even add '"' around the file names
to get it absolutely (?) foolproof.

If you are using a compiler which supports POSIX libraries, such as
the Intel compiler, it is trivial. First call PXFLINK to create a new
link to the data, then PXFUNLINK to remove the old link to the data:
character(100) :: oldfn, newfn
:
call PXFLINK (oldfn, len_trim (oldfn), newfn, len_trim (newfn), ierr)
if (ierr /= 0) some error occurred...
call PXFUNLINK (oldfn, len_trim (oldfn), ierr)
if (ierr /= 0) some error occurred...

I'm working on PC, using Compaq visual fortran.

CVF uses "SYSTEM" to send a command to the OS shell. Alternatively,
there are the necessary interfaces and data structures to the
underlying Win32 API routines CopyFile or MoveFile defined in the
KERNEL32 module supplied as one other alternative. Of course, this is
also compiler- and OS-specific so the ususal caveats apply...

Oh, and lest I forget, there's also the RENAME() and RENAMEFILEQQ()
routines in the DFPORT and DFLIB modules that are wrappers to the APIs
already prepared. For some reason they didn't provide higher level
wrappers for copy or move. RENAME, of course, on Win32 fails across
different media so that is a restriction as opposed to others but is
potentially much quicker if files are large in avoiding an actual
physical copy operation.

If you are indeed a *user* rather than a *programmer*, you may find it
simpler to separate the math from the housekeeping, and call both your
fortran code and the system utilities from a makefile, a shell script,
or one of the many scripting languages.

Perhaps this was too terse for a novice, so I'll elaborate. Fortran is
easy if you stick to math, but otherwise things can get quite
complicated. So for simplicity do the math in fortran, try to find some
simple high-level tool for anything else, and glue everything together
in a script. I usually do this with an extra target or two in the same
makefile that builds the fortran executable. Learning to use makefiles
(and to build libraries) is worth the hassle even for an occasion/casual
*user*.
