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 folder2    folder3

Adding the below function in bashrc lets you run the command without any arguments which displays the current directory structure and when run with any path as argument, will display the directory structure of that path. This avoids the need to switch to a particular directory before running the command.

function tree() {
    find ${1:-.} | sed -e "s/[^-][^\/]*\//  |/g" -e "s/|\([^ ]\)/|-\1/"
}

This works in gitbash too.

Is this what you re looking for tree  It should be in most distributions  maybe as an optional install      gt  tree -d  proc self   proc self   -- attr  -- cwd - gt   proc  -- fd      -- 3 - gt   proc 15589 fd  -- fdinfo  -- net      -- dev snmp6      -- netfilter      -- rpc          -- auth rpcsec context          -- auth rpcsec init          -- auth unix gid          -- auth unix ip          -- nfs4 idtoname          -- nfs4 nametoid          -- nfsd export          -- nfsd fh      -- stat  -- root - gt     -- task      -- 15589          -- attr          -- cwd - gt   proc          -- fd            -- 3 - gt   proc 15589 task 15589 fd          -- fdinfo          -- root - gt     27 directories   sample taken from maintainer s web page   You can add the option -L   where   is replaced by a number  to specify the max recursion depth   Remove -d to display also files

I m prettifying the output of  Hassou s answer with   ls -R   grep        sed -e  s       -e  s   -          -- g  -e  s -     -e   s         This is much like the output of tree now      -pkcs11  -pki  ---ca-trust  -----extracted  -------java  -------openssl  -------pem  -----source  -------anchors  -profile d  -ssh   You can also make an alias of it   alias ltree   ls -R   grep        sed -e   s        -e   s   -          -- g   -e   s -      -e    s           BTW  tree is not available in some environment  like MinGW  So the alternate is helpful

You can use this one    ls -R   grep        sed -e  s       -e  s   -          -- g  -e  s         -e  s -       It will show a graphical representation of the current sub-directories without files in a few seconds  e g  in  var cache             -apache2     ---mod cache disk     -apparmor     -apt     ---archives     -----partial     -apt-xapian-index     ---index 1     -dbconfig-common     ---backups     -debconf   Source

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   Source  Comment from  javasheriff here  Its submerged as a comment and posting it as answer helps users spot it easily

Since I was not too happy with the output of other  non-tree  answers  see my comment at Hassou s answer   I tried to mimic trees output a bit more  It s similar to the answer of Robert but the horizontal lines do not all start at the beginning  but where there are supposed to start  Had to use perl though  but in my case  on the system where I don t have tree  perl is available  ls -aR   grep  quot    quot    perl -pe  s      s   -               g s        S   --  1  s                           g s       S   --  1    Output  shortened      -- fd  -- net         -- dev snmp6         -- nfsfs         -- rpc                -- auth unix ip         -- stat         -- vlan  -- ns  -- task         -- 1310                -- net                       -- dev snmp6                       -- rpc                              -- auth unix gid                              -- auth unix ip                       -- stat                       -- vlan                -- ns  Suggestions to avoid the superfluous vertical lines are welcome  -  I still like Ben s solution in the comment of Hassou s answer very much  without the  not perfectly correct  lines it s much cleaner  For my use case I additionally removed the global indentation and added the option to also ls hidden files  like so  ls -aR   grep  quot    quot    sed -e  s       -e  s   -             g   Output  shortened even more       fd   net     dev snmp6     nfsfs     rpc       auth unix ip     stat     vlan   ns

You can also use the combination of find and awk commands to print the directory tree  For details  please refer to  How to print a multilevel tree directory structure using the linux find and awk combined commands   find   -type d   awk -F        depth 3  offset 2  str        path     if NF  gt   2  amp  amp  NF  lt  depth   offset        while offset  lt  NF            path   path                offset               print path   --   NF

To add Hassou s solution to your  bashrc  try   alias lst  ls -R   grep        sed -e      s           -e      s   -          -- g      -e      s             -e      s -

Since it was a successful comment  I am adding it as an answer  with files   find     sed -e  quot s   -              g quot  -e  quot s            - 1  quot
