This is why relative paths have problems sometimes. There isn't a good way to handle absolutely any relative path, because all relative paths have an assumption:
the current working directory is "x".
You are assuming /home/polypus. Unix tools are designed to do one thing very well. It's hard to make a bulletproof tool because of the cwd assumption.
Because:
Obviously it may not be true.
So, there is no really elegant way to deal with it. You're onto one way to deal with it.
For programming, you should consider avoiding relative paths unless you want the code to work if and only if it runs from a certain directory.

Hi,
I have a file with about 60 lines of path:
app-defaults/boxXYZ.......
I want to change this to /my/path/goes/here/app-defaults/boxXYZ, but of course vi doesn't like the regualr :s/old/new/ command.
Is there any other quick way to do this?
Thanks ;) (2 Replies)

shtool-mkln
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).
