Question

I am new to bash scripts. I’m just trying to make a script that will search through a directory and echo the names of all subdirectories.

The basis for the code is the following script (call it isitadirectory.sh):

     #!/bin/bash

     if test -d $1
         then
                echo "$1"
     fi

so in the command line if I type

       $bash isitadirectory.sh somefilename 

It will echo somefilename, if it is a directory.

But I want to search through all files in the parent directory.

So, I’m trying to find a way to do something like

           ls -l|isitadirectory.sh

But of course the above command doesn’t work. Can anyone explain a good script for doing this?

Answer 1

Following lines may give you an idea…what you are asking for

#!/bin/bash

for FILE in `ls -l`
do
    if test -d $FILE
    then
      echo "$FILE is a subdirectory..."
    fi
done

You may have a look into bash ‘for’ loop.
