tree command?

There does not seem to be such a package - you can search for packages with pkcon search NAME.

There is a similar approach you can use, it will list the contents of the current directory as a tree style format.

So if you just wanted to see the 'tree' of /home/nemo then you would type:

ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'

Or move to a particular directory, say root, then you would need to 'devel-su'; (the same command as above but with devel-su added)

devel-su ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'

If you wanted to 'print' your tree to a file for later viewing, add > my-tree.text to the end of the file, like this;

ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/' > my-tree.text

When the text file is viewed, It should look like the following, which is part of my '/home/nemo' directory;

   |-CallRecordings
   |-Desktop
   |-Documents
   |-Music
   |---Alanis Morissette - JLP Acoustic
   |---Frou Frou - Details
   |---playlists
   |-Pictures

thank you @szopin. Downloaded and [root@Sailfish nemo]# pkcon install-local tree-1.7.0-10.9.1.jolla_.armv7hl.rpm did work great.

I went the openrepos route, but thank you for the interesting code (quite some grep/sed magic in there!)

@szopin you should convert your comment to an answer, seeing as your response comes much closer to what the OP asked for.
