[erlang-questions] os:cmd/1 does not work for ulimit -n

[MAthuvathanan Mou.]

Hi all,

Using Linux (RedHat) I wanted to increase number of open files for that
session only (temporarily)

In the erl shell I did

erl
Erlang (BEAM) emulator version 5.5.5 [source] [async-threads:0] [hipe]
[kernel-poll:false]

Eshell V5.5.5  (abort with ^G)
1> os:cmd('ulimit -n').
"1024\n"
2> os:cmd('ulimit -n 2048').
[]
3> os:cmd('ulimit -n').
"1024\n"
4>

Why did open file not increase here?

Regards,
