Linux command to print directory structure in the form of a tree

Question

Is there any linux command that I can call from a Bash script that will print the directory structure in the form of a tree, e.g.,

folder1
   a.txt
   b.txt
         


        

Answer 1

This command works to display both folders and files.

find . | sed -e "s/[^-][^\/]*\// |/g" -e "s/|\([^ ]\)/|-\1/"

Example output:

.
 |-trace.pcap
 |-parent
 | |-chdir1
 | | |-file1.txt
 | |-chdir2
 | | |-file2.txt
 | | |-file3.sh
 |-tmp
 | |-json-c-0.11-4.el7_0.x86_64.rpm
