XCOPY Alternative in UNIX

Expand Post »
Hi all,
Can you please tell me if there is a bash command in UNIX that is similar in functionality to XCOPY in Windows? XCOPY can copy who directory trees from a source folder to a destination folder, but from what I saw about the cp command in bash, it is not possible. Also XCOPy can copy only new files, and returns if files were copied or not. I would like if the bash command did that as well. Here is the XCOPY functional specs for further reference. You can find if files had been copied or not by looking at the XCOPY return codes.

Thanks in advance.
Shane

Re: XCOPY Alternative in UNIX

Obviously you haven't looked very carefully at the man page.
Copying directory trees (recursive mode):
cp -r
Copying directory trees, viewing all files copied (verbose mode):
cp -rv

You can string any of the cp options together, like that.

Re: XCOPY Alternative in UNIX

oh. sorry I missed something in my question. I wanted to selectively copy the files in the source directory into the destination directory. Say for example all the .h files and .c files. XCOPY can do this by using the /S switch.

Shell Scripting Syntax (Toggle Plain Text)
  1. SomeFolder
  2. |
  3. +--Source
  4. |
  5. +--Dest
if you type
Shell Scripting Syntax (Toggle Plain Text)
  1. XCOPY /S *.h ..\dest
it will recursively copy the .h files in source to dest while retaining the directory structure.

I tried it with cp but it didnt do that.
Shell Scripting Syntax (Toggle Plain Text)
  1. $ cp -R *.h ../temp
  2. cp: cannot stat `*.h': No such file or directory
  3.  
Is there any way i can do that in bash?

You need a path. You can't just put "*.h". You need either to use working directories, or the full path:
cp -r somefolder/*.h ../someotherfolder

Re: XCOPY Alternative in UNIX

I am afraid that doesn't work. Only the files in the somefolder is copied to the destination. Recursive seraching is not done. Can you please try the above command and see if my observation is correct.
Create a folder like this.

Shell Scripting Syntax (Toggle Plain Text)
  1. ├─dest
  2. └─source
  3.     │--test1.h
  4.     │
  5.     └─child
  6.            └─test2.h
The above command


Shell Scripting Syntax (Toggle Plain Text)
  1.  cp -r source/*.h dest
doesnt copy the test2.h file in the child directory. Only the test1.h is copied.

Re: XCOPY Alternative in UNIX

The reason cp -r source/*.h is not working is because you've only told it to look at .h files. For that reason, it doesn't copy the child directory (since it's not a .h file itself), much less its contents (though they may be .h files).

Re: XCOPY Alternative in UNIX

So how do I tell to look for .h files in child folders as well? I want to copy them so that the directory structure is the same as the source directory structure. I hope you understand what I am trying to do here. I only want the shell command please. I have looked the documentation of cp and tried all combinations. So if you know the exact answer please reply.
