Hi,

i have a problem to use a system command from inside gnuplot.

sed -i 's/^\xef\xbb\xbf//' ./process-2023-11-02-13-04-40.csv

works at the terminal


system "sed -i 's/^\xef\xbb\xbf//' ./process-2023-11-02-13-04-40.csv"
and
system(sprintf("sed -i 's/^\xef\xbb\xbf//' 
./process-2023-11-02-13-04-40.csv"))

in a gnuplot script do not work, but gnuplot shows me

GPVAL_SYSTEM_ERRNO = 0
GPVAL_SYSTEM_ERRMSG = "Success"


as a test I try

system "cp ./process-2023-11-02-13-04-40.csv 
./process-2023-11-02-13-04-40.test"

this works, the file process-2023-11-02-13-04-40.test was created.


what's wrong?
