Help with folder and file difference
Hello,

I was wondering how to make difference between file and folder while using ls -l?

I see it on the output because "d" is for dir and "-" for file, but how to make this input to other command?

Because I am trying to bzip2 if it's the file and tar if it's a directory.

using tests:
Code:
if [ -f $file ]
then
   echo " $file is an ordinary file"
fi
if [ -d $file ]
then 
     echo " $file is a directory " 
fi

These 2 tests, you should be able to figure out how to use them for you needs

You can use find command along with '-type' switch to filter out files and dirs. E.g.:

Code:
find /somewhere -type d | xargs tar -cvf something.tar

Okey, so I tried using both methods. With first one I jsut failed, because I tried something like that:
Code:
ls -lrt | tail -1
if [ -f $file ]
then 
bzip2 $file #
fi
if [ -d $file ]
then
tar -xf $file 
fi

OUTPUT:
Code:
  is an ordinary file
  is a directory

I know it may look dumb for you, but I know it's got wrong syntax.

second methods just zips me ALL the files and DIRS in the folder. :/

Code:
FILE=$(ls -rt | tail -1)

if [ -f $FILE ]
then
   echo " $FILE is an ordinary file, using bzip..."
   bzip2 $FILE 
elif  [ -d $FILE ]
then
   echo " $file is a directory, using tar "
   tar -xf $FILE
fi

then
   echo " $file is a directory, using tar "
   tar -xf $FILE
fi

nearly OK, but my terminal spams:
Code:
bzip2: Input file 1.sh.bz2 already has .bz2 suffix.
bzip2: Input file 1.sh.bz2 already has .bz2 suffix.
bzip2: Input file 1.sh.bz2 already has .bz2 suffix.
bzip2: Input file 1.sh.bz2 already has .bz2 suffix.
bzip2: Input file 1.sh.bz2 already has .bz2 suffix.

So it was done the first time already...

You would have to test if the file given in input ($FILE) has already the .bz2 suffix...
