UNIX for Dummies Questions & Answers

Here is my question in bash

for f in f1 f2
do
cd $f
cd ??? # i need to enter the two layers of sub folders then find the folder named "abcde" ?
cd .. # how to get out two layers subdirectories?
cd ..
done

Code:

ls -d ./*/*/abcde

?

Code:

find ./ -type d -name "abcde" -depth 3

Thank you very much!

Here is what I need to do. Thanks a lot!

The folder structure is

under f1 and f2,

a list of subfolders, some contain folder name containing "abcde"
if there is "abcde", then there is file in "*abcde*" named "file.txt", then I will grep "xxyyzz"
if there is no folder name containing "abcde", then I need to go back and go to another subfolders and continue

then all the patterns will be stored in a file new$f

-------------------
for f in f1 f2
do
cd $f
#then I need to loop one layers sub directories and if there is folder named "abcde", I need to grep pattern from "file.txt". If no folder "abcde", then back one layer up and repeat finding "abcde" --- how to do this? Thanks a lot!

#find the "file.txt" and grep pattern
find .-name "file.txt" -exec grep "xxyyzz" {} \; > new$f
cd ..
done
