create list of directories and use it in script

[liondari]

Hello everybody, how are you?

I hope someone can help me!

I would like to write a script which zips automatically
a complete directory structure.
For example, there is a directory dirA which contains, say,
5 subdirs sdirA1 .. sdirA5.
Another dir dirB which contains 3 subdirs sdirB1 .. sdirB3. And so on.
Now I would like to zip each subdir in dirA and dirB separately:

for i in list_of_directories <---dirA,dirB,..
do
cd $i
for j in list_of_subdirs <---sdirA1..sdirA5,sdirB1..
do
tar -cf $j.tar $j/*
bzip2 $j.tar
done
cd ..
done

Thank you in advance!

As a start point try:
find /path/to/dirA -type d

to produce a list of full path names to all sub-directories in dirA

I hope that helps.

Try

for i in *         #for each entry
do
  if [ -d $i ]     #if entry is a directory
  then
    cd $i          #cd to that directory
    for j in *     #for each entry
    if [ -d $j ]   #if entry is directory
    then
                   #tar and zip it up
      tar -cf - $j | bzip2 -c > ${j}.tar.bz
    fi
    cd ..          #back to parent directory
  fi
done

You might want to replace the for j in * with for j in $(ls) as I'm not quite sure where the script is going to expand the '*'
Please also note there is no error checking!!. If any of the cd $i fails then the script will run out of control. I've also used the -c glag for bzip2 on the grounds that it is correct for gzip and I believe they're compatible. This needs testing
