How to "cd $variable" when the variable tries to add "\" before spaces (path contain spaces)?

  • 772

My bash script registers its own path so it can return to its own folder after doing a cd somewhere (kinda if it explores a different forest and is able to relocate its house).

And if the path have spaces, I've used sed to add \ before every space.

But when using cd $SCRIPTPATH to this variable:

./newsed.sh: 11: cd: can't cd to /media/daniell/B/bkp/ST500LM012\

Source: newsed.sh:

#!/bin/bash -e

tmp="$( cd -- "$(dirname "$0")" >/dev/null 2>&1 ; pwd -P )"
SCRIPTPATH="$(echo "$tmp" | sed 's/ /\\ /g')"

echo "$SCRIPTPATH"

ls
cd
ls
cd $SCRIPTPATH
ls

echo $SCRIPTPATH produces a normal path (/media/daniell/B/bkp/ST500LM012\ HN-M500MBB\ Dat/0/ok/Pendrive/flshdrive/0.Floflis-DNA/layers/soil) that I can manually copy and cd into it, and works; but when cd'ing directly to the variable (cd $SCRIPTPATH) it crashes right after the \.

bash

  1. Use quotes around variables to prevent spaces from being treated as delimiters in the shell, i.e.

    cd "$SCRIPTPATH"

    will work.
