Bash script cd doesn't work

Part of my bash script is to access a series of folders:

 #lsit of folders
locations=("/Volumes/Israel\ Hernandez/Quantitative\ Data/Microglia\ data/3\ month/Mutant/314a"
    "/Volumes/Israel\ Hernandez/Quantitative\ Data/Microglia\ data/3\ month/Mutant/314b"
    "/Volumes/Israel\ Hernandez/Quantitative\ Data/Microglia\ data/3\ month/Mutant/314c")

for i in "${locations[@]}"
do (
    #change to directory

    cd "$i"
    #convert tiff to png

However when I received errors:

/Users/luna/Documents/Ethan/scripts/microglia.sh: line 16: cd: /Volumes/Israel\ Hernandez/Quantitative\ Data/Microglia\ data/3\ month/Mutant/314a/: No such file or directory

I've tried to just cd into that folder on terminal and it absolutely worked. How come it just wont work in a shell script?

before you cd command, you should process the escape space in you $i. here is the code, hope it helps.

#lsit of folders
locations=("/Volumes/Israel\ Hernandez/Quantitative\ Data/Microglia\ data/3\ month/Mutant/314a"
    "/Volumes/Israel\ Hernandez/Quantitative\ Data/Microglia\ data/3\ month/Mutant/314b"
    "/Volumes/Israel\ Hernandez/Quantitative\ Data/Microglia\ data/3\ month/Mutant/314c")

for i in "${locations[@]}"
do (

    #reverse esxape chars such space in you code
    i="echo \$\'"$(echo $i|sed -e 's|\\|\\\\|g')"\'"
    i=$(eval "echo $(eval $i)")
    i=$(eval "echo $(eval $i)")

    #change to directory
    cd "$i"
    #convert tiff to png

The error is clearly:"No Such file or directory!" You can executive the command "cd /Volumes/Israel\ Hernandez/Quantitative\ Data/Microglia\ data/3\ month/Mutant/314a/" on the terminal.
if the error is "No such file or directory!",you should carefully check the path. Don't doubt the script parser itself!Just doubt your code!

You don't need the backslash escapes before the spaces since the spaces are already inside a double-quoted string. Your quoting is correct — rejoice! Remove the backslashes inside your "" strings and you should be set.
