Now I am using gnuplot (Version 5.2 patchlevel 6) on a Linux system.

The information of operating system as follow:
Linux version 4.4.162-94.72-default (geeko@buildhost) (gcc version 4.8.5 (SUSE Linux) )
LSB Version: n/a
Distributor ID: SUSE
Description: SUSE Linux Enterprise Server 12 SP3
Release: 12.3
Codename: n/a

My question:
I am trying to launch a system command in gnuplot like
Terminal type is now 'qt'
gnuplot> system(" paste <(ls Q) <(ls F)")

show me the error message as
sh: -c: line 0: syntax error near unexpected token (' sh: -c: line 0: paste <(ls Q) <(ls F)'

But if I exit the gnuplot and run the command, it can work.
qin@csc1:~/qin /txt> paste <(ls Q) <(ls F)

any help would be much appreciated
have a nice day
