ksh directory comparison script


I'm pretty new to shell scripting and need to write a script that will add a dash to sets of numbers and take the new numbers(directory names) and compare them with currently existing directories creating a new document. If the directories are there, I need the number and size, otherwise I need the number and it to say closed. So far:

Code:
#!/bin/ksh

sed -e 's/\(...\)\(....\)/\1-\2/' directories.txt

if [ ! -d unk ] ; then
	print closed
else
	du unk > dir.txt
fi
Where I put "unk" means I'm not sure what I should do there. I have been searching and reading and haven't found a simple way to take what the sed command gives me and test that. There's gotta be a better way to do this but I can't think of it atm.

I have no idea what you're trying to do, but from your code I guess you want this:

Code:
#!/bin/ksh

cd /path/to/somewhere

touch newdirectory.txt

while read dirname 
do
  dirname=`echo $dirname"-"`
  if [  -d  $dirname  ] ; then
	echo "$dirname `du $dirname`" >> newdirectory.txt                
  else
                echo "$dirname not found"
  fi
done <  /path/to/directories.txt

Thanks for the reply, I'll give it a shot.

Giving it a try. I'm understanding this a little better but I don't think this is what I need. I need to take a txt document that has a listing of directories that may or may not exist and add a "-" taking them from 0000000 to 000-0000(hence the sed command.) I would then need to test the new listing that I'll get from the sed command to see if the directories exist(printing du or closed along with the directory name.) I'd like to be able to take the output of the sed and run it through the if loop.

I think this will do what you want:

Code:
for rec in `cat t.t`
do
    t1=`echo $rec|cut -c1-3`
    t2=`echo $rec|cut -c4-7`
    t3=${t1}-${t2}
    echo $t3 >>t2.t
done
for rec in `cat t2.t`
do
    if [[ -d $rec ]]
    then
        echo $rec is a dir
    fi
done
where t.t is:
1234567
2345678

you'll get a t2.t:
123-4567
234-5678

which is then tested rec by rec as dirs.
