expanding dotted paths to absolute ones in bash or sh
I have a little script to help me manage a gallery of image files. It makes symbolic links to every file in and below the current directory, placing them in a target directory which is passed to the script as a parameter. Unfortunately, the script pukes when I pass a parameter that contains dotted paths.
$ linkall /home/joe/foo
$ linkall ~/foo
work beautifully. The latter one works because the parameter is expanded before it is passed.
But,
$ linkall ../foo
pukes.
Does anyone know of a way to expand the passed parameter into an absolute path? I've tried everything I can think of. I'm having a hard time even thinking of the right query to Google for. Whenever that happens, I look for a forum.
It seems to me that I'm probably looking for some code that gets used in a lot of scripts; basically boilerplate that I've just never come across yet.
Other than by strictly using absolute paths, I can't think of any workarounds off the top of my head.
I can post the script if that would help. It's 68 lines.

build-lives-rfx-plugin-multi - builds rendered effects for LiVES SYNOPSIS
build-lives-rfx-plugin-multi type [scripts_dir exec_dir] [build_bindir] DESCRIPTION
This perl script builds rendered effects (RFX) plugins for LiVES. If scripts_dir is not defined then type is used to locate the plugin scripts directory and output directory. Type can be builtin (the default), custom, test, or builtinx. The type builtinx forces scripts_dir and exec_dir to be read from parameters and is used during LiVES install, and is the only type which should be used if scripts_dir is specified. Each plugin script in input directory is scanned to find its language code. The script is then passed to the script compiler for that lan- guage. The directory location of the script_compiler may be specified by the build_bindir parameter (as is the case during LiVES installa- tion0; otherwise the user's $PATH will be searched. Return values the script returns the following values 0 - success 1 - the "type" parameter was not defined, or set to an invalid value 3 - the builder for a plugin script was not found SEE ALSO
