Cygwin bash: read file word by word

I want to read text file word by word. Problem: there are some words containing "/*". Such a word causes script to return files in root directory. I tried:

for word in $(< file)
do
    printf "[%s]\n" "$word"
done

And several other combinations with echo/cat/etc... For this file:

/* example file

I get following output:

[/bin]
[/cygdrive]
[/Cygwin.bat]
...
[example]
[file]

Should be easy but it's driving me nuts.

How about this one?

while read -a a; do printf '[%s]\n' "${a[@]}"; done < file

Output:

[/*]
[example]
[file]

How about this solution, the double quotes around $(< file) stop * from being expanded and sed is used format the output as required:

for word in "$(< file)" 
do
    echo "$word" | sed -E 's/(\S*)(\s)/[\1]\2\n/g'
done

Output:

[/*] 
[example] 
[file]

You need to turn off pathname expansion globbing. Run a new shell with bash -f and try again. See http://wiki.bash-hackers.org/syntax/expansion/globs or dive into the manpage with man bash, maybe do man bash | col -b >bash.txt.

this may help; 

# skip blank lines and comment lines begining with hash (#)

cat $CONFIG_FILE | while read LINE
  do
  first_char=`echo $LINE | cut -c1-1`
  if [ "${first_char}" = "#" ] 
   then
      echo "Skip line with first_char=  >>${first_char}<<"
   else
     :
     echo "process line:  $LINE"  ;
   fi

done

Another way is to use a case statement
