I'm pretty new to programming and shell and I'm not having an issue with the script below, it's working perfectly but I want to know if I can do better.
I'm inserting the content of some CSV files (value1, value2, value3) into an html table. I'm using a while loop (easier for me), but I think there might be a simpler way to do it.
Is it possible to have the below script in one single while loop? I want to echo different text depending on the value of the variable. Thanks
echo "<!DOCTYPE html>
<html>
<style>
tr, td {
border: 1px solid black;
border-collapse: collapse;
text-align: center;
}
table {
width: 75%;
}
h2 {
color: navy;
text-transform: uppercase;
}
h3 {
color: navy;
text-transform: uppercase;
padding-top:50px;
}
</style>"
var1 ="value1"
for a1 in $var1; do
echo "<h2>text1</h2>
<table>"
print_header=true
while read INPUT ; do
if $print_header;then
echo "<tr><span style="text-transform:uppercase"><td><b>${INPUT//,/</b></td><td><b>}</b></td></span></tr>";
print_header=false
else
echo "<tr><td>${INPUT//,/</td><td>}</td></tr>" ;
fi
done < $a1;
echo "</table>"
done
var2="value2 value3"
for a2 in $var2; do
echo "<h2>text2</h2>
<table>"
print_header=true
while read INPUT ; do
if $print_header;then
echo "<tr><span style="text-transform:uppercase"><td><b>${INPUT//,/</b></td><td><b>}</b></td></span></tr>";
print_header=false
else
echo "<tr><td>${INPUT//,/</td><td>}</td></tr>" ;
fi
done < $a2 ;
echo "</table>"
done
