For loop and read from different directories
Hello,
I need to grep/read files from multiple directories, one by one.
I mean something like shuffling the cards uniformly.

Code:
cd /directoryA
for i in *.txt;
do
some codes 
cd ../directoryB
for i in *.txt;
do
some codes
cd ../directoryC
for i in *.txt;
do
some codes
done
done
done

Directory A Includes: (Lets say totally 100 files)
Code:
1.txt
2.txt
3.txt
4.txt
5.txt
..
..
..
100.txt

Directory B Includes: (Lets say totally 30files)
Code:
a.txt
b.txt
c.txt
d.txt
e.txt
..
..
..
z.txt

Directory C Includes: (Let's say totally 901 files)
Code:
101.txt
102.txt
103.txt
104.txt
105.txt
..
..
..
1000.txt

In first for loop 1.txt should be read from directory A
  • 1st loop -> directory A, file 1.txt
  • 2nd loop ->directory B, file a.txt
  • 3rd loop -> directory C, file 101.txt
  • 4th loop -> directory A, file 2.txt

If all files in a certain folder had already been read in previous loop, skip that folder...

I'd appreciate if you could explain how I can do that. for is causing problem. Other solutions are also welcome.

Many thanks
Boris
