嘿伙计们！我在编写 bash 脚本以运行我的脚本 50 次时遇到问题，该脚本生成数据文件然后将其绘制到文件中。我是这样写的，但它不起作用
#!/bin/bash
for i in {1..50}
do
./ampl ampltst1 # generates different res.txt file each time
/usr/bin/gnuplot <<\__EOF
set xrange [-2:2]
set yrange [-2:2]
set term png
set output "image-${i}.png"

Possibly you have problems with indentation: __EOFmust be without any leading spaces:
可能你有缩进问题：__EOF必须没有任何前导空格：
...
/usr/bin/gnuplot <<\__EOF
set xrange [-2:2]
...
__EOF
done
Also \symbol is not required.
也\没有所需的符号。
Also content of HERE-IS-DOCUMENT will be indented. Is that OK for gnuplot?
HERE-IS-DOCUMENT 的内容也将缩进。gnuplot 可以吗？
If no, you must remove indentation:
如果不是，则必须删除缩进：
for i in {1..50}
do
./ampl ampltst1 # generates different res.txt file each time
/usr/bin/gnuplot <<__EOF
set xrange [-2:2]
set yrange [-2:2]
set term png
set output "image-${i}.png"
plot "res.txt" u 1:2 w lines, "res.txt" u 3:4 w lines, "res.txt" u 5:6 w li$
pause -1
__EOF
done
