Can't find unexpected operator (Bash error)

I've created a开发者_JS百科 simple Bash script that should create symlinks in /usr/local/{etc,lib,include...} from an inputted directory path

#!/bin/sh

input="$1"
for subdir in "etc include bin lib man share sbin"; do
   dir=$input/$subdir
   if [ -e $dir ] && [ -d $dir ]; then
      for file in $dir/*; do
         ln -s $file /usr/local/$subdir
      done
   fi
done

The error i'm getting is:

user@comp:/usr/local# ./update-locallinks /usr/local/test/
[: 6: /usr/local/test/etc: unexpected operator

and this is what /usr/local/test/ looks like:

user@comp:/usr/local# ls /usr/local/test/
bin
etc
include
lib

Always protect your bash variables with double quotes in test expressions:

   if [ -e "$dir" ] && [ -d "$dir" ]; then

---

for subdir in "etc include bin lib man share sbin"; do

Why the quotes? Change that to:

for subdir in etc include bin lib man share sbin; do

otherwise $dir will contain etc include bin ... on the first (and only) iteration.
