[rancid] F5 backups are only working for some hosts via cron, but always manually

Well, I can say after several tests that I have probably found the 
problem, but I don’t understand it.

The command:
clogin -t 90 -c"bigpipe version;bigpipe platform;cat /config/bigip.license;bigpipe monitor list all;bigpipe profile list;bigpipe base list;bigpipe db show;bigpipe route static show;ls --full-time --color=never /config/ssl/ssl.crt;ls --full-time --color=never /config/ssl/ssl.key;bigpipe list" bigip2b

a) called directly from the rancid user shell
b) called from the root shell via „su - rancid -c <command>”

Looking at the different outputs of the problematic lines I can see the 
following:
a)
[root at bigip2b:Standby] config # ls --full-time --color=never /config/ssl/ssl.crt^M
<output>
[root at bigip2b:Standby] config # ls --full-time --color=never /config/ssl/ssl.key^M
<output>
[root at bigip2b:Standby] config # bigpipe list^M
<output>

b)
[root at bigip2b:Standby] config # ls --full-time --color=never /config/ssl/ssl.crt ^M^[[A[root at bigip2b:Standby] config # ls --full-time --color=never /config/ssl/ssl.cr^[[Kt^M
<output>
ls --full-time --color=never /config/ssl/ssl.key^M
[root at bigip2b:Standby] config # ls --full-time --color=never /config/ssl/ssl.key ^M^[[A[root at bigip2b:Standby] config #total 64^M
<output>
e[root at bigip2b:Standby] config # bigpipe list^M
<output>

So besides the CR characters the second output shows some other control 
characters which probably confuses the parser in the end.

Is this the right conclusion? But why do I get these additional control 
characters in the second case?

Shade and sweet water!
