echo “Load avarage: $LSTART $rload $LEND”
should really read
echo “Load average: $LSTART $rload $LEND”
I have installed this script in to /var/www/html/ directory and changed name to info.html.
I ran this script from command line
#./info.html
and I got an error line 110
and 126
What is next how do I run this script?
Hello Dipak.
We cannot read what you put in lines 110 and 126.
Try to be more explicit.. (next time if you want gurus to help you try to give them the informatons they need to debug ).
this script is running under the linux box and display the results on a page, so try to visit http://the_server_where_the_script_is_running/info.html.
Try it it post your results …
Moussa NDIAYE: If you were such a “guru” you would probably guess that he just copied the script as is,
cat -n somefile gets you linenumbers…guru my ass ;)
