bash shell loop through directory listing contents and executability

Question

I'm currently working on a homework assignment and I need to take a given directory path and from that list the files and directories in it. While also including if it's executable or not. I'm also restricted by not being allowed to use any other languages except bash.

My original thought was to use ll and cut to get what I needed but I couldn't seem to get it to work. Then I was thinking I could use something like (not working, just an idea)

read input
for f in $input
do
if [[ -x "$f" ]]
then
echo "$f is executable"
else
echo "$f is not executable"
fi
done

I need the output to be something like and I'm not sure how to get there

file-name1 is executable

file-name2 is not executable

directory1 is executable

• MelBurslan: can you tell how this code is failing ? [[ -x filename ]] is a perfectly legitimate construct in bash. Would you be using some other shell may be ?
• DopeGhoti: Rather than for f in $input, try for f in ${input}/*. Making sure the value of $input is a readable directory is an exercise I shall leave for you.
• Jeff Schaller: why are you looping over $input? On the assumption that the user is entering "a (single) directory path"...
• DopeGhoti: As I see it, the OP's intent is to loop over the contents of the directory specified as the input.

Answer 1

Try like

my=($(ls -la $dr |awk {'print 9ドル'})) 
echo ${my[@]} 
for i in "${my[@]}" 
do 
 if [[ -x "$i" ]] 
 then 
 echo "File '$i' is executable" 
 else 
 echo "File '$i' is not executable or found" 
 fi 
done 

• Piyush Jain: $dr you can replace with your directory.
• DopeGhoti: Don't parse the output of ls.
• Piyush Jain: tmp]$ ./test.sh . .. 1 2 3 4 5 a b c d e File '.' is executable File '..' is executable File '1' is not executable or found File '2' is not executable or found File '3' is not executable or found File '4' is not executable or found File '5' is not executable or found File 'a' is not executable or found File 'b' is not executable or found File 'c' is not executable or found File 'd' is not executable or found File 'e' is not executable or found
• DopeGhoti: No, seriously, don't parse ls. mywiki.wooledge.org/ParsingLs

Answer 2

You're taking a directory and then checking to see whether the directory itself is executable, and not looking into its contents as you want to.

read input
for f in ${input}/*; do
 echo -n "$f is "
 type=""
 if [[ -x "$f" ]]; then
 type="executable"
 else
 type="non-executable"
 fi
 if [[ -d "$f" ]]; then
 type="$type directory"
 fi
 echo "$type"
done

Making sure the value of $input is a readable directory is an exercise I shall leave for you.
