shtool-mkshadow
SHTOOL-MKSHADOW.TMP(1) GNU Portable Shell Tool SHTOOL-MKSHADOW.TMP(1)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@engelschall.com> in 1998 for Apache. It was later
revised and taken over into GNU shtool.
