Yiling Liu's questions

代码：

#!/usr/bin/env bash
# download death data
wget -O Deaths.txt http://www.randomservices.org/random/data/Deaths.txt
wget -O Pumps.txt http://www.randomservices.org/random/data/Pumps.txt
# Delete the first line
sed 1d Deaths.txt > tempfile1
sed 1d Pumps.txt > tempfile2
# mv tempfile1 Deaths.txt
# mv tempfile2 Pumps.txt
gnuplot -persist -e "set terminal canvas;set xlabel 'x' font 'sans,15';
set ylabel 'y' font ',15';
set title 'Relationship between Deaths and Pumps' font 'sans, 20';
show title;
set label "Most of the deaths is near the pump located in 12.6,11.7" at 16,16;
show label;
set output 'death_pump_relation.html';
plot 'Pumps.txt' with points pt 7 ,'Deaths.txt' with dots;"

有一个错误：line 0: unexpected or unrecognized token

我无法得到任何输出

但其实我的脚本里没有line0

那有什么问题？

版本：gnuplot V5.2

系统：MacOS

我想用 ' ' 替换所有符号，如 '.'、'-'、'/' 等

我试过sed 's/[[!:alnum:]]/ /g' example.txt但它不起作用

而对于sed 's/[,;\.\-\/()_]/ /g' example.txt，我发现我无法将 '-' 替换为 ' '。

有什么办法吗？

代码：

if [ $mintemp -ge 15 && $maxtemp -le 28 ]; then echo "nice day"; fi

我已经在 [ 和 $Mintemp 、 28 和 ] 之间有空格

但错误仍然发生
