I have a problem with my script, I cannot generate an HTML report of all the IPs which are pinged thanks to the list of IPs which are specified when the script is launched. Could someone help me please, thank you very much for your help which will be essential for the smooth running of the school project.

CodePudding user response：
You have (at least) quoting problem on your html. All " will be remove by the shell. To keep a '"' escape it like this \" or suround it by '
If you just print your html on a terminal you will not see any " I think (not tested).
For more debuging give us more information please.
CodePudding user response：
Use a here doc to get a string without processing substitutions.
htmlsite=$(cat - <<EOF
<html lang="en">
...
</html>
EOF
)
CodePudding user response：
I see from your comment that your sendmail is not working.
The command seems to be fine per se and it works on my machine.
Make sure that you can manually send messages out with that command: if not you need to troubleshoot your sendmail setup.
Also your resultatping variable gets the output of your ping command but the result is sent to the file mail.txt without HTML: the variable htmlsite is never used.
Finally IMHO it's probably not a great idea to call a variable ping and use it as an argument for the ping command...
