151203 2003-06-09 06:30:00 I have been asked to wirte a bash script to display the following as the output :

>filestats /bin /etc /var /etc/password /usr/sbin

/bin : 0 ordinary, 86 executable, 0 directories, 15 links.
/etc : 144 ordinary, 6 executable, 65 directories, 15 links.
/var : 0 ordinary, 0 executable, 19 directories, 1 links.
/etc/passwd : is not a directory
/usr/sbin : 15 ordinary, 232 executable, 0 directories, 49 links.

I have gotten as far as this with the script:

clear

if [ $# ieq 0 ]

then
DirList = "$PWD"elif
DirList = "$*"


for
Dir in $DirList do
Dir ls $Dir


for
File in 'ls $Dir 'do

if[ -f $File ]
then files=$(($files + 1))
if [ -x $File ]
then execF=$(($execF + 1))
if [ -d $File ]
then dire=$(($dire + 1))
fi


fi

done


echo: "numfiles:"$files
echo: "numexecF":$execF
echo: "numexecF":$execF
done


Im really stuck now ... can anyone out there help me ???

Please???
Thank you ??

Bash is really picky about where you put spaces etc compared to other languages . If you need some examples of the syntax have a look in the system startup scripts, thats what I used to learn .

That should be enough to get it to run without errors . But its not complete .

A couple of other tips:
- Have a look at "declare -i" in the man page, it makes arithmetic easier .
- If you want to handle spaces in filenames correctly, you will need to have a play with the IFS variable .
- Throwing an "echo $Dir" and "echo $File" into the loops will make debugging a lot easier . 		bmason (508)
151205 2003-06-09 12:38:00 Thanks alot bmason! I know about the spacing part, but the post automatically formatted it like that. ( I wanted to show everyone exactly how i wrote it but I guess that didnt work)

Yeah I havent completed it..... Another thing is.. what command do I use to get the output onto one line .... do i use either grep or cut??
Thank you ...

Just join the echo lines:

echo "numfiles: $files exec: $execF directorys: $execF" 		bmason (508)
