Hi everyone,
is there any way to recall a command of a long time ago fast and without searching back day by day or is there any log file which saves the command history externally in R2014a?
many thanks in advance

Search it directly!

it's not possible what I need belongs to nearly one year ago and I can not find it anymore in my command history directly!

Then it's probably gone. The XML file that holds the command history only holds X number of lines where X is set in the preferences.

To make things like such searches possible I have this in my startup.m-file:
filename = fullfile('/home','bjorn','matlabruns',[datestr(clock,30) '.txt']);
diary(filename)
That saves all commandline-input/output in one file for each matlab session. Then I can search for commands and snippets from any-time ago. I find this a very helpful trick - that I learnt by someone very cunning.
HTH - in the future at least

You can find the file history.xml in prefdir
fid=fopen(fullfile(prefdir,'history.xml'))
a=textscan(fid,'%s','delimiter','\n')
fclose(fid)
text=a{:}
