shtool-mkshadow (1) Linux Manual Page
NAME
shtool mkshadow – GNU shtool create shadow tree using symlinks
SYNOPSIS
shtool mkshadow [-v|–verbose] [-t|–trace] [-a|–all] src-dir dst-dir
DESCRIPTION
This command creates a shadow tree of src-dir under dst-dir by recreating the directory hierarchy of src-dir under dst-dir and by creating the files of src-dir by linking them into the corresponding directories under dst-dir via symbolic links. When src-dir can be reached via relative paths from dst-dir, relative symbolic links are used, too. This high-level functionality is originally designed for developers to create copies of source trees.
OPTIONS
The following command line options are available.
-v,–verbose- Display some processing information.
-t,–trace- Enable the output of the essential shell commands which are executed.
-a,–all- Really shadow all files and directories in src-dir. Default is to skip CVS related files and directories, backup files, object files, etc.
EXAMPLE
# shell script shtool mkshadow -v -a . /tmp/shadow
HISTORY
The GNU shtool mkshadow command was originally written by Ralf S. Engelschall <rse [at] engelschall.com> in 1998 for Apache. It was later revised and taken over into GNU shtool.
