Here we can see that we have one directory ( d in drwxrwxr-x), named Folder_one, and 2 files. rwxrwxrwx 1 marija marija 164461 large.jpg The result of this command should look something like: total 15168ĭrwxrwxr-x 3 marija marija 4096 Jul 18 19:26 Folder_one The -l option will modify the ls command to give you much more detailed info, such as whether an entry is a file or directory, the size (usually in bytes), modified date and time, permissions, and more: $ ls -l You can use them alone, or by combining a few of them, depending on what exactly are you looking for. The ls command has several non-mandatory options which, when turned on, give us much more about these files when listing them. Though, these are just the names, and we can't infer much from them. Hence, we need to process the output of ls -R in reverse order, from the last line to the first.Alternatively, you can supply a directory name to list files from, without having to move to that directory: $ ls Folder_one The code gives better-looking results than other solutions because in a tree of subdirectories, the decorations in any branch depend on the branches below it. If (below = blank) tip(elbow) else tip(tee)įor (row = 1 row <= NR row++) print path If (stem) tip(pipe) # if.: stem is empty at first!įor (d = 1 d < growth d++) stem = stem blankīelow = substr(stem, length(stem) - 4, 4) # gsub: count (and clean) all slash-ending components hence, # Model each stem on the previous one, going bottom up. First, an example of output:įunction tip(new) Įlbow = '└── ' pipe = '│ ' tee = '├── ' blank = ' ' But, to improve on other answers that rely on grepping the output of ls -R, here is a shell script that uses awk to print a tree of subdirectories. For my use case I additionally removed the global indentation and added the option to also ls hidden files, like so: ls -aR | grep ':$' | sed -e 's/:$//' -e 's/*// /g' 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. Suggestions to avoid the superfluous vertical lines are welcome :-) Had to use perl though, but in my case, on the system where I don't have tree, perl is available. 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. 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.
