+## find-files-extension
+
+### Instructions
+
+Create a file `find-files-extension.sh`, which will look, from the current directory and its sub-folders for:
+
+all the files with `.txt` extension.
+
+That command will only show the name of the files without the extension `.txt`.
+
+- You can use this for testing: https://assets.01-edu.org/devops-branch/find-files-extension-example.zip
+
+- What to use : `find`
+
+- The output should be exactly like the example bellow but with the expected name
+
+```console
+$pwd
+<..>/find-files-extension-example
+$./find-files-extension.sh | cat -e
+qwep$
+pq1$
+zzzz$
+ziko$
+wei$
+ek$
+$
+```
+
+### Hints
+
+`find` command is used to search and locate the list of files and directories based on conditions you specify for files that match the arguments:
+You can use REGEX in `find` command.
+
+```console
+$find ~/ -iregex '<REGEX>'
+<all files and folders in the user home that respect the specified regex>
+$
+```
+REGEX for txt files: `.*\.\(txt\)`
+
+`cut` command is a command-line utility that allows you to cut out sections of a specified file or piped data and print the result:
+
+```console
+$cat cut-example.txt 
+abc-lol
+testtest-abcx
+qwerty-azerty-x
+$cat cut-example.txt | cut -d "-" -f 1 # cut the lines with "-" as delimiter and print the first part.
+abc
+testtest
+qwerty
+$
+```
+
+May you will need to use `pipe (|)` and `&&`.
+
+> You have to use Man or Google to know more about commands flags, in order to solve this exercice!
+> Google and Man will be your friends!
