LFTP - Create directory if it does not exist

Question

I would like to use LFTP to create a directory if it does not exist. It should be a "one-liner":

This does already work:

lftp -c "open -u user,pass server; mkdir /test

The

lftp -c "open -u user,pass server; mkdir -p /test

fails if the directory already exists:

mkdir: Zugriff nicht möglich:550-Can't create directory: File exists 16 files used (0%) - authorized: 50000 files 1286621 Kbytes used (0%) - authorized: 512000000 Kb (/test2)

But it does fail if the directory does already exist. How can I do this more elegant?

did you try googling this? I get a number of results, including: [this](https://github.com/welaika/wordmove/issues/103) and [this](http://stackoverflow.com/questions/4171236/lftp-mkdir-p-doesnt-work-with-sftp-protocol). In other words, are you using the latest version of `lftp`? — Matthias, Aug 25 '16 at 11:47
Yes, I tried to. LFTP is `LFTP | Version 4.0.9 | Copyright (c) 1996-2010 Alexander V. Lukyanov` which is installed from the repo. — MyFault, Aug 25 '16 at 11:51
yeah I can't seem to find an answer there either. But there [is](https://lftp.yar.ru/news.html) a newer version of LFTP, you could try to upgrade and see if that helps. — Matthias, Aug 25 '16 at 11:54
still wouldn't get my hopes up, from the same page as in my comment above: Version 3.7.12 - 2009-04-28 fixed core dump on `mput -d' command. fixed a core dump on `kill' command. fixed mkdir -p for sftp protocol. fixed some signed/unsigned conversion bugs. — Matthias, Aug 25 '16 at 11:58

You can use mkdir -f option to suppress the error message. The option is available starting with 4.5.2 version. The latest lftp version is 4.7.3.

If you can't upgrade to the latest version of lftp, you can use this :

lftp -c "cd /my/new/directory || mkdir -p /my/new/directory"

It will create the directory only if it can't enter it.

Do you mean simply mkdir -p /test?

Answered here: How to mkdir only if a dir does not already exist?

From the mkdir --help:

-p, --parents no error if existing, make parent directories as needed

I added this to my initial question. The -p does not work. – MyFault Aug 25 '16 at 11:43

lftp's mkdir does not equal to the linux shell's mkdir – Ilya Kharlamov Apr 03 '19 at 20:16
