Change directory without using 'cd' [closed]

Question

I have a list of files with their paths in a text file. And I want to copy these files, mentioned in list, to another directory with their parent folders tree. Also my shell-script to copy these files is in the same directory as this text-file.

Now I have put this text file inside a directory and I want to copy files as listed in the text file from the parent folder of the current directory of text file.

List of files is like below:

../app/code/community/Company/Module/Block/Adminhtml/Location.php
../app/code/community/Company/Module/Block/Adminhtml/Location/Edit.php
../app/code/community/Company/Module/Block/Adminhtml/Location/Grid.php

../skin/frontend/default/default/module/js/module_bak_21052016.js

Now I know cp --parents can copy the file along with it's parent directories and re-create structure if necessary, but how can I change directory just by passing ../ to the cp command, so that it picks up file from parent folder and not look for it in current folder ?

Answer 1

how can I change directory just by passing ../ to the cp command

You can not pass a "change directory" argument (comparable to the -C option of tar, for example) to any version of cp I have ever seen. Earlier, I suggested simply doing a cd in the shell script, before issuing the cp command, but that was deemed unhelpful, too.

Answer 2

These are my assumption:

File structure in the original place:

..
├── app
│   ├── code
│   ├── design
│   ├── etc
│   └── locale
│   └── ...
├── script.d
│   ├── file.list
│   ├── script.sh
└── skin
    └── frontend
    └── ...

file.list is the name of the file containing the list of files to be copied. script.sh is the following script.

#! /bin/bash

distDir="THE NEW DIRECTORY PATH" # <<<<<< Alter this line

for filePath in $(cat "file.list");
do
    len=$(wc -c "$filePath")
    newFilePath=$(cut -c4-$len "$filePath")

    tempFileName=$(grep -Po '[^/]+$' "$filePath")

    path=$(grep -Po '^.*/' "$newFilePath")

    newPath=$distDir

    for dir in $(echo "$path" | tr / '\n');
    do

        if [ $(ls "$newPath" | grep -P '^'$dir'$' | wc -l) = 0 ]
        then
            mkdir "$newPath"'/'"$dir"
            newPath="$newPath"'/'"$dir"
        fi

    done

    cp "$filePath" "$newPath"'/'
done

Just make sure you give the correct path in the first line.
