To mkdir `*/pictures`

Question

My folder tree

.
|-- 1
|-- 2
|-- 3
...
|-- 777

I would like to create the folder pictures to each folder.

I run unsuccesfully

mkdir */pictures

One way is of course creating 777 mkdir -commands with Vim's regex. However, I would know how you can do that in shell.

How can you mkdir */pictures?

Answer 1

for x in `seq 1 777`
do
    mkdir $x/pictures;
done

Also, in the past you have mentioned zsh and this should work without modification under at least bash and zsh.

Answer 2

Almost the same as others, but adding a slash, so it only counts directories and not regular files

for x in */
do
    mkdir $x/pictures;
done

Answer 3

Many ways to do this, I think this is the simplest:

for f in *; do mkdir $f/pictures; done

This is quick and dirty and will make a subdirectory for everything in your current directory. You will get harmless errors if there are files in the current working directory. If that bothers you a more complex solution using find or seq or the like is better. If your directories are numbered then a simpler version of Sean's seq example (in bash) is

mkdir {1..777}/pictures

BTW, mkdir can easily make several directories at once:

mkdir 1/pictures 2/pictures

The problem is that */pictures doesn't expand to anything in the shell since the directories don't exist yet.

Answer 4

for i in *; do cd $i; mkdir pictures; cd ..; done

Edit: I noticed that someone beat me to the punch so I'll improve the script a bit (test whether it is a directory):

for i in *; do if [ -d $i ]; then cd $i; mkdir pictures; cd ..; fi; done

Answer 5

I'm going to assume you're using bash...

find . -mindepth 1 -maxdepth 1 -type d | while read dir; do mkdir $dir/pictures; done

or if everything in the directory is a directory

ls | while read dir; do mkdir $dir/pictures; done

If you're using tcsh, you have to do this with an inelegant for loop.

Answer 6

mkdir ~/Pictures
mkdir ~/container
mkdir ~/container/1
mkdir ~/container/2
mkdir ~/container/3
mkdir ~/container/4
mkdir ~/container/5

cp -r ~/Pictures ~/container/**/
rm -rf ~/Pictures

This will do the trick, i've just tried it

Answer 7

How about:

find . -mindepth 1 -maxdepth 1 -type d -exec mkdir {}/pictures \;

Answer 8

I tested it out and this should be what you need:

#!/bin/bash 
list=$(/bin/echo *)

for file in $list
do
    if [ -d $file ]; then
    	cd $file
    	mkdir picture
    	cd ..
    	echo "Added folder to $file"
    fi
done
