Hi,

thanks for your answer... Actually it didn't work. My data is gzipped and the shell script looks like this now:

Code:
#!/usr/bin/env zsh

for f in *.asc.gz ; do
  eps_file=`basename $f .asc.gz`.eps

  gnuplot <<EOF
    unset key
    set xrange [-15:15]
    set yrange [-15:15]
    set xlabel "X (pc)" font "Helvetica,12"
    set ylabel "Y (pc)" font "Helvetica,12"
    set terminal postscript eps enhanced ; set output "$eps_file"
    set pointsize 1
    plot "< `zcat $f`" using 3:4 with dots lt 8, plot "< `zcat $f | gawk -v NAME=60001 '/AS/ {TIME=$4} $1==NAME {print TIME,$2,$3,$4,$5,$6,$7,$8,$11; exit}'`" using 3:4 with points pt 6 lt -1
    unset output
EOF
done

but I get just a lot of

Code:
gnuplot> 3205  0.163931745191803E-04 -0.907177552580833E-01  0.397187858819962E+00  0.159223228693008E+00 -0.691880345344543E+00  0.227686256170273E+00 -0.249464988708496E+00  0.298150134086609E+01 -0.151934671401978E+01  0.437424212694168E+00          0
         ^
         line 0: invalid command


gnuplot> 3206  0.163931745191803E-04 -0.413754805922508E-01  0.191585481166840E+00 -0.704685896635056E-01  0.115810036659241E+00 -0.425811052322388E+00  0.161283984780312E+00  0.504894542694092E+01 -0.163576829433441E+01  0.208285257220268E+00          0
         ^
         line 0: invalid command

But I guess one should somehow "protect" the shell commands wrapped within gnuplot... if it's not ` ` then what??
