SYNCTREE(1)						      General Commands Manual						       SYNCTREE(1)

synctree - synchronize directory trees. SYNOPSIS
synctree [-iuf] [[user1@]machine1:]dir1 [[user2@]machine2:]dir2 DESCRIPTION
Synctree synchronizes the directory tree rooted at dir2 with dir1. It walks recursively through both trees, and deletes and adds files in dir2 to make it equal to dir1. Mode, owner and group are set for each file unless the -u flag is given. In its normal mode of operation, synctree will ask if it may delete or add directories assuming that you don't want to. Non-directories are simply deleted or added, but synctree will ask if it needs to update a normal file with a default answer of 'y'. Simply typing return will choose the default answer, typing end-of-file is like typing return to this question and all other questions. You can specify a hostname and user-id to be used to access dir1 or dir2. Synctree will use rsh(1) to run a copy of itself on the remote machine. The call interface mimics that of rcp(1), but you can use more than one user@machine prefix if you want to make things really interesting. Hard links are enforced, an update is done by first deleting the old file so that links to unknown files are broken. Links to files within dir2 will be restored. If either directory contains the file .backup, then this file will be used as an alternate inode table. This allows one to make a backup copy of a file tree full of special files and differing user-ids on a remote machine under an unpriviledged user-id. OPTIONS
-i Ask for permission (with default answer 'n') to delete or add any file or directory. -u Only install newer files, i.e. merge the directory trees. -f Don't ask, think 'yes' on any question. SEE ALSO
remsync(1), cpdir(1), rsh(1), rcp(1), perror(3). DIAGNOSTICS
Messages may come from three different processes. One named "Slave" running in dir1, one named "Master" running in dir2, and synctree itself in a mediator role. The mediator will also perform the task of either the master or the slave if one of them is running locally. You need to know this to interpret the error messages coming from one of these processes. The messages are normally based on perror(3). Failure to contact a remote machine will be reported by rsh. Synctree should have a zero exit status if no errors have been encountered. BUGS
Directory dir2 will be created without asking. The master and slave processes get their error output mixed up sometimes (nice puzzle). The local and remote machine must use the same file type encoding. The link replacement strategy may lead to lack of space on a small device. Let synctree run to completion and then rerun it to pick up the pieces. Letting the local process keep its "synctree" name may be a mistake. It talks too much. AUTHOR

mv - Moves files and directories SYNOPSIS
mv [-i | -f] [--] file1 file2 mv [-i | -f] [--] file1... directory mv [-i | -f] [--] directory1... destination_directory The mv command moves files from one directory to another or renames files and directories. STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: mv: XCU5.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. OPTIONS
Overrides the -i option and any mode restrictions. (If both -f and -i are specified--for example, because an alias includes one of them--whichever appears last overrides the other.) Prompts you with the name of the file followed by a question mark whenever a move is to supersede an existing file. If the answer begins with y, or the locale's equivalent of a y, the move continues. Any other reply prevents the move from occurring. (If both -f and -i are specified--for example, because an alias includes one of them--whichever appears last over- rides the other.) Interprets all following arguments to mv as file names. This allows file names to start with a - (dash). DESCRIPTION
If you move a file to a new directory, mv retains the original file name. When you move a file, all other links to the file remain intact. In the second form, one or more files are moved to directory with their original file names. In the third form, one or more directories are moved to the destination directory with their original names. The mv command does not move a file onto itself. When you use mv to rename a file, the target file can be either a new file name or a new directory path name. If moving the file would overwrite an existing file that does not have write permission set and if standard input is a terminal, mv displays the permission code of the file to be overwritten and reads one line from standard input. If the line begins with y, or the locale's equivalent of a y, the move takes place and the file is overwritten. If not, mv does nothing with the file. When you use mv to move a directory into an existing directory, the directory and its contents are added under the existing directory. The LC_MESSAGES variable determines the locale's equivalent of y or n (for yes/no queries). If a mv operation fails, mv generally writes a diagnostic message to standard error, does nothing more with the current source file, and goes on to process any remaining source files. If the copying or removal of a file is prematurely terminated by a signal or error, mv might leave a partial copy of the file at either the source or the target path name. The mv program does not modify the source and target path names simultaneously; therefore, program termina- tion at any point always leaves either the source file or the target file complete. NOTES
[Tru64 UNIX] If the source is on a different file system than the destination, mv must copy the source to the destination's file system and then delete the source. The effect is equivalent to the following: rm -f destination && cp -pr source destination && rm -rf source The mv command might overwrite existing files. Specify the -i option last on the command line to cause the mv command to prompt you before it moves a file. EXIT STATUS
The following exit values are returned: All files were moved successfully. An error occurred. EXAMPLES
To rename a file, enter: mv file1 file2 This renames file1 to file2. If a file named file2 already exists, its old contents are replaced with those of file1. To move a directory, enter: mv dir1 dir2 This moves dir1 to dir2. It moves dir1 and all files and directories under dir1 to the directory named dir2, if the second direc- tory exists. Otherwise, the directory dir1 gets renamed dir2. To move a file to another directory and give it a new name, enter: mv file1 dir1/file2 This moves file1 to dir1/file2. The name file1 is removed from the current directory, and the same file appears as file2 in the directory dir1. To move a file to another directory, keeping the same name, enter: mv file1 dir1 This moves file1 to dir1/file1. To move several files into another directory, enter: mv file1 dir1/file2 /u/dir2 This moves file1 to /u/dir2/file1 and dir1/file2 to /u/dir2/file2. To use mv with pattern-matching characters, enter: mv dir1/* . This moves all files in the directory dir1 into the current directory (.), giving them the same names they had in dir1. This also empties dir1. Note that you must type a space between the * (asterisk) and the (dot). ENVIRONMENT VARIABLES
The following environment variables affect the execution of mv: Provides a default value for the internationalization variables that are unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization vari- ables contain an invalid setting, the utility behaves as if none of the variables had been defined. If set to a non-empty string value, overrides the values of all the other internationalization variables. Determines the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as opposed to multibyte characters in arguments). Determines the locale for the for- mat and contents of diagnostic messages written to standard error. Determines the location of message catalogues for the processing of LC_MESSAGES. SEE ALSO
