I don't see an immediate reason why your script should run slow. Try using the -x (xtrace option to isolate where / which line it has its difficulties; mayhap the remote login?
Please post all files' contents so people get a chance to follow what you are doing.
Can you explain how to implement that xtrace? Is this an option on SCP? I can't find it in the manpage

And here is my reason that I think it can be better. It logs in each time it needs a file, instead of log in once and then gets ALL the files off and after that, it should log off and log on to the next server. in my noob opinion, this would save time. Correct me if I am wrong. I just don't know how to do that.
For two servers now it takes about 10 seconds, but in production, it will be a lot more and some are fast responding and some are not, so I want to have the script as fast as possible.

there is not much to it.
I have three plain text files
1 with two servers in it, each server on its own line like:
192.168.122.7
192.168.122.74

1 with the path to the files needed like this:
/path/to/file
/path/to/file2

also each on its own line.

the last file is the password file and has only one password in it. I don't need the password in production, because the script server already has root access to all the other servers and doesn't need to log in.

Some remarks:
[QOUTE]- you use arrays, but don't increment / modify the respective indices?[/QUOTE]
do you have a link to an explanation what you mean, so I check that and learn?
Quote:
- you're using FOUR nested loops, to what avail?
one for error handling (show a message and exit the script when the folder that needs to be empty, doesn't exist.)
one to loop through the servers
one to create the folders per server name
one to loop through the file paths

Quote:
- how do you expect to use ssh_pass variable / file on various servers?
As I explained above I don't need that in production but have that in place for my test VM's, they both have the same password, so I don't need to run through that file.

I included my log file to this message

Thanks for the quick response btw!

With kind regards,

Cornelis

NAME
syslogout - modular centralized shell logout mechanism DESCRIPTION
syslogout is a generic approach to enable centralized shell logout actions for all users of a given system in a modular and centralized way mostly aimed at avoiding work for lazy sysadmins. It has only been tested to work with the bash shell. It basically consists of the small /etc/syslogout shell script which invokes other small shell scripts having a .bash suffix which are con- tained in the /etc/syslogout.d/ directory. The system administrator can drop in any script he wants without any naming convention other than that the scripts need to have a .bash suffix to enable automagic sourcing by the /etc/syslogout script. For shell sessions, the contents of /etc/syslogout.d/" will be sourced by every user at logout if the following lines are present in his $HOME/.bash_logout: if [ -f /etc/syslogout ]; then . /etc/syslogout fi If used for X sessions it is advisable to include the former statement into the Xreset script of the X display manager instead to prevent that closing of an terminal emulator window yields unexpected results in your running X session if your X11 terminal emulator is using a login shell. Be sure then to run it under the user-id of the X session's user. See the example files in /usr/share/doc/syslogout/ for illustration. Users not wanting /etc/syslogout to be sourced for their environment can easily disable it's automatic mechanism. It can be disabled by simply creating an empty file called $HOME/.nosyslogout in the user's home directory using e.g. the touch(1) command. Any single configuration file in /etc/syslogout.d/ can simply be overridden by any user by creating a private $HOME/.syslogout.d/ directory which may contain a user's own version of any configuration file to be sourced instead of the system default. It's names have just to match exactly the system's default /etc/syslogout.d/ configuration files. Empty versions of these files contained in the $HOME/.syslo- gout.d/ directory automatically disable sourcing of the system wide version. Naturally, users can add and include their own private scripts to be automagically executed by /etc/syslogout at logout time. OPTIONS
There are no options other than those dictated by shell conventions. Anything is defined within the configuration scripts themselves. SEE ALSO
The README files and configuration examples contained in /usr/share/doc/syslogout/ and the manual page for bash(1), xdm(1x), xdm.options(5), and wdm(1x). Recommended further reading is everything related with shell programming. If you need a similar mechanism for executing code at login time check out the related package sysprofile(8) which is a very close compan- ion to syslogout. BUGS
syslogout in its current form is mainly restricted to bash(1) syntax. In fact it is actually a rather embarrassing quick and dirty hack than anything else - but it works. It serves the practical need to enable a centralized bash configuration until something better becomes available. Your constructive criticism in making this into something better" is very welcome. Before i forget to mention it: we take patches... ;-) AUTHOR
syslogout was developed by Paul Seelig <pseelig@debian.org> specifically for the Debian GNU/Linux system. Feel free to port it to and use it anywhere else under the conditions of either the GNU public license or the BSD license or both. Better yet, please help to make it into something more worthwhile than it currently is. SYSLOGOUT(8)
