List files recursively in Linux CLI with path relative to the current directory

Use find:

find . -name \*.txt -print

On systems that use GNU find, like most GNU/Linux distributions, you can leave out the -print.

Try find. You can look it up exactly in the man page, but it's sorta like this:

find [start directory] -name [what to find]

so for your example

find . -name "*.txt"

should give you what you want.

Use tree, with -f (full path) and -i (no indentation lines):

tree -if --noreport .
tree -if --noreport directory/

You can then use grep to filter out the ones you want.

---

If the command is not found, you can install it:

Type following command to install tree command on RHEL/CentOS and Fedora linux:

# yum install tree -y

If you are using Debian/Ubuntu, Mint Linux type following command in your terminal:

$ sudo apt-get install tree -y
