moving files with patron in directories to specific directory-CodePudding

I got a bunch of directories with names like (I cannot change anything about go this are generated):

yyyy-MM-dd hh.mm.ss DIR1 File 01 random_number/    
yyyy-MM-dd hh.mm.ss DIR2 File 06 random_number/
yyyy-MM-dd hh.mm.ss DIR3 File 11 random_number/
etc

where random_number is a 11 digit random integer. Every directory has a file named something.ext (the same name for every one). There is also a directory called done where I move the directories that I already processed.

I rename the something.ext files and copy them to another directory, manually like this:

cd yyyy-MM-dd\ hh.mm.ss\ DIR1\ File\ 01\ random_number/
mv something.ext File\ 01.ext
cp File\ 01.ext /path/to/DIR1/
cd ..
mv yyyy-MM-dd\ hh.mm.ss\ DIR1\ File\ 01\ random_number/ done/

cd yyyy-MM-dd\ hh.mm.ss\ DIR2\ File\ 06\ random_number/
mv something.ext File\ 06.ext
cp File\ 06.ext /path/to/DIR2/
cd ..
mv yyyy-MM-dd\ hh.mm.ss\ DIR2\ File\ 06\ random_number/ done/

etc

Is there any way i can automate this through a script? I'm not really good filtering names and stuff... I'm familiar with bash and python scripting...

I'm assuming that all you have in the initial directory is your "bunch of directories" plus the done directory. Also, for testing purposes, I made the /path/to/ equal to ./done/ so that /path/to/DIR1/ is equal to ./done/DIR1/, /path/to/DIR2/ is equal to ./done/DIR2/, and so on. My test directory tree looks like this:

$ find .
.
./done
./done/DIR1
./done/DIR2
./done/DIR3
./yyyy-MM-dd hh.mm.ss DIR3 File 11 random_number
./yyyy-MM-dd hh.mm.ss DIR3 File 11 random_number/something.ext
./yyyy-MM-dd hh.mm.ss DIR2 File 06 random_number
./yyyy-MM-dd hh.mm.ss DIR2 File 06 random_number/something.ext
./yyyy-MM-dd hh.mm.ss DIR1 File 01 random_number
./yyyy-MM-dd hh.mm.ss DIR1 File 01 random_number/something.ext
$

You can achieve your mvs and cps with a simple bash loop like this:

for i in *; do
    if [ "$i" == "done" ]; then
        continue;
    fi;
    file=$(echo $i | awk '{print $4 " " $5}').ext;
    todir=./done/$(echo $i | awk '{print $3}');
    mv "$i/something.ext" "$i/$file";
    cp "$i/$file" "$todir";
    mv "$i" done;
done

Here is the directory tree and files after running the script:

$ find .
.
./done
./done/DIR1
./done/DIR1/File 01.ext
./done/DIR2
./done/DIR2/File 06.ext
./done/DIR3
./done/DIR3/File 11.ext
./done/yyyy-MM-dd hh.mm.ss DIR1 File 01 random_number
./done/yyyy-MM-dd hh.mm.ss DIR1 File 01 random_number/File 01.ext
./done/yyyy-MM-dd hh.mm.ss DIR2 File 06 random_number
./done/yyyy-MM-dd hh.mm.ss DIR2 File 06 random_number/File 06.ext
./done/yyyy-MM-dd hh.mm.ss DIR3 File 11 random_number
./done/yyyy-MM-dd hh.mm.ss DIR3 File 11 random_number/File 11.ext
$

You could use the =~ operator for regex pattern matching inside a for loop, which was a feature of bash starting from bashv3 . A subshell is useful when using cd and not worrying if and when you need to exit the current directory.

#!/usr/bin/env bash

regex='^(. ) (. ) (. ) (. ) (. ) (. )$'

for directory in */; do
  if [[ $directory =~ $regex ]]; then
    dir_num0="${BASH_REMATCH[3]}"
    dir_num1="${BASH_REMATCH[4]} ${BASH_REMATCH[5]}"
    (
      printf 'Going inside directory [%s]\n' "$directory" 
      cd "$directory" || exit
      echo mv -v -- something.txt "$dir_num1.ext" || exit
      echo cp -v -- "$dir_num1.ext" "/path/to/$dir_num0" || exit
    )
    echo mv -v -- "$directory" done/ || exit
  fi
done

With your given sample input/data the output is:

Going inside directory [xxx-xx-xx xx.xx.xx DIR3 File 11 x/]
mv -v -- something.txt File 11.ext
cp -v -- File 11.ext /path/to/DIR3
mv -v -- xxx-xx-xx xx.xx.xx DIR3 File 11 x/ done/
Going inside directory [xxx-xx-xx xx.xx.xx DIR1 File 01 xx/]
mv -v -- something.txt File 01.ext
cp -v -- File 01.ext /path/to/DIR1
mv -v -- xxxx-xx-xx xx.xx.xx DIR1 File 01 x/ done/
Going inside directory [xxxx-xx-xx xx.xx.xx DIR2 File 06 x/]
mv -v -- something.txt File 06.ext
cp -v -- File 06.ext /path/to/DIR2
mv -v -- xxxx-xx-xx xx.xx.xx DIR2 File 06 x/ done/

The =~ test/regex operator supports E.R.E
Place the script inside the directory in question and execute it. Or place the script within your PATH and go inside the top directory of the files/directories in question.
Remove the echo's if you're satisfied with the output.
The regex/pattern regex='^(. ) (. ) (. ) (. ) (. ) (. )$' matches 6 fields with a space as the delimiter/separator. It can be made more specific to your directory names.

Something like

regex='^([[:digit:]]{4}-[[:digit:]]{2}-[[:digit:]]{2}) ([[:digit:]]{2}\.[[:digit:]]{2}\.[[:digit:]]{2}) (. ) (. ) ([[:digit:]] ) ([[:digit:]] )/$'
