shtool-mkshadow - GNU shtool create shadow tree using symlinks
shtool mkshadow [-v|--verbose] [-t|--trace] [-a|--all] src-dir dst-dir
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.
The following command line options are available.
Display some processing information.
Enable the output of the essential shell commands which are executed.
Really shadow all files and directories in src-dir. Default is to skip CVS related files and directories, backup files, object files, etc.
# shell script shtool mkshadow -v -a . /tmp/shadow
The GNU shtool mkshadow command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1998 for Apache. It was later revised and taken over into GNU shtool.
