mv command: mv vs rename operation
Hi all,
I wish to know about a simple concept of mv command in UNIX. Is moving a file to a different directory takes longer than renaming it in the same direcotry using the mv command?
The scenerio is that I have to transfer a file from one directory to a location which is regularly scanned by some "program" for the file. This "program" moves the file to some other system. Now if the input file is huge, the "program" may transfer the file before the whole file is moved to this location.
So I decided to move the file with a different name to the second location. Once this operation is complete then I would rename the file to the original name so that the "program" can transfer the file.
My query is that whether the renaming would take same time as move operation? If so, then my approach may not work......Please suggest......
Thanks in advance.

mvdir(1) General Commands Manual mvdir(1)
NAME
mvdir - Moves (renames) a directory
SYNOPSIS
mvdir directory1 directory2
DESCRIPTION
The mvdir command renames directories within a file system. To use mvdir, you must have write permission to directory1 and directory2 and
to the parent directories of directory1 and directory2. The directory1 argument must name an existing directory. If directory2 does not
exist, directory1 is moved to directory2. If directory2 exists, directory1 becomes a subdirectory of directory2. directory2 cannot be a
subdirectory of directory1.
Directories cannot be moved across file systems.
You can also rename a directory with the mv command.
NOTES
This command was made obsolete by the mv command.
EXAMPLES
To rename or move a directory to another location, enter: mvdir appendixes manual
If manual does not exist, then this renames the directory appendixes to manual.
If a directory named manual already exists, this moves appendixes and its contents to manual/appendixes. In other words, appendixes
becomes a subdirectory of manual.

Functions: rename(2)
