Converting relative path into absolute path?
absolute-path, path, perl, shell, unix
Solution
From this source comes:
#!/bin/bash
# Assume parameter passed in is a relative path to a directory.
# For brevity, we won't do argument type or length checking.
ABS_PATH=`cd "$1"; pwd` # double quotes for paths that contain spaces etc...
echo "Absolute path: $ABS_PATH"
You can also do a Perl one-liner, e.g. using `Cwd::abs_path`
Problem
I'm not sure if these paths are duplicates. Given the relative path, how do I determine absolute path using a shell script? Example: ``` relative path: /x/y/../../a/b/z/../c/d absolute path: /a/b/c/d ```
