Hi,

I'm having a small issue here and I can't get it to work. I'm programming a script for bash and I need to do something to all the folder in a directory. So I'm in the directory and I want to use the foreach statement but I dont know how to reference all the folders of that directory. To make things simplistic here's my code:

foreach instance (.)
cd instance
mkdir test
end

Something like this:

for file in *; do
   if [ -d $file ]; then
      cd $file; mkdir test
   fi
done

A small correction blowtorch.

for file in *; do
   if [ -d $file ]; then
      mkdir $file/test; 
   fi
done

Hi, I had a question about the cd thing, how come it doesn't work? I'm modifying the code to go into certain subfolders in each folder and then execute a command so I wasn't sure how to do that. Basically I'm trying to do something like this now...

current directory:
a b c

Inside of each directory there is a file here (using a as an example):
a/test/folder/script.sh

Sorry for the generic names. Now what I want my script to do is access that script.sh in each folder and run it. I was gonna do the for statement and then cd into that path and then do an execute command but I guess it's not that simple. Any ideas? thanks!

You can try like

for file in *; do
   if [ -d $file ]; then
      ./$file/test/folder/script.sh; 
   fi
done

scriptHome=$(pwd)   # Assuming that you are running from the path where a b c are present
for file in *; do
   if [ -d $file ]; then
      cd $file/test/folder;
      ./script.sh
   fi
   cd $scriptHome
done

Your main problem here was not logic, but that you were using the syntax from the wrong shell. This is csh syntax.

Thanks guys. So basically there is no foreach command in bash?
