SHTOOL-MKLN.TMP(1)					      GNU Portable Shell Tool						SHTOOL-MKLN.TMP(1)

NAME
shtool-mkln - GNU shtool enhanced ln(1) replacement SYNOPSIS
shtool mkln [-t|--trace] [-f|--force] [-s|--symbolic] src-path [src-path ...] dst-path DESCRIPTION
This is a ln(1) style command. It is enhanced to provide automatic calculation and usage of relative links with the shortest possible path, if possible. Usually if src-path and dst-path are not absolute paths or at least they share a common prefix except the root directory (``"/"''). When more than one src-path is specified, all of them are linked into dst-path. OPTIONS
The following command line options are available. -t, --trace Enable the output of the essential shell commands which are executed. -f, --force Force the creation of the link even if it exists. Default is to fail with error. -s, --symbolic Create a symbolic link instead of a hard-link. EXAMPLE
# shell script shtool mkln -s foo/bar baz/quux HISTORY
The GNU shtool fixperm command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1998 for ePerl. SEE ALSO
shtool(1), ln(1). 18-Jul-2008 shtool 2.0.8 SHTOOL-MKLN.TMP(1)
