Hi All,
Have a piece of code which makes a curl to a webpage and returns a list of host which are currently up/down (down hosts are derived from grep -A1 DOWN command below and saved to a tmp file)
From that file I need to generate a URL and call it to mark the hosts as up. The URL that needs to be generated is like this -
http://$HOST:$PORT/URI/$host-from-tmp-file:$port-from-tmp-file
where
$host-from-tmp-file would need to come from the tmp file (/tmp/mon_prd.tmp)
$port-from-tmp-file would need to come from the tmp file (/tmp/mon_prd.tmp)
ENV1) HOST=`command | awk -F: '{print $1}'` PORT=`command | awk -F: '{print $2}'|head -1` for i in $HOST do curl -s "http://$i:$PORT/virtual/hostlist" | grep "DOWN" curl -s "http://$i:$PORT/virtual/hostlist" | grep -A1 "DOWN" > /tmp/mon_prd.tmp if [ `echo $?` -eq 0 ] then mail -s "Subject" mail@mail.com < /tmp/mon_prd.tmp fi echo -n "" > /tmp/mon_prd.tmp done ;; *) echo "Invalid option" ;; esac
Thanks,
Allan.
Solved! Go to Solution.

Allan:
Post a sample (or two) of the *contents* of your '/tmp/mon_prd.tmp' file, As usual, showing actual data leads to better solutions than making assumptions based on vague descriptions.
Snipping out the data you need to construct your URL should be quite simple.

No need for head(1):
PORT=$(command | awk -F: '{print $2; exit}')
>if [ `echo $?` -eq 0 ]
I'm not sure why you are using echo?
if [ $? -eq 0 ]; then
And better to use mailx vs mail.

Right, but you meant to write that as:
PORT=$(command | awk -F: '{print $2;exit}')

Hi JRF
Sample of /tmp/mon_prd.tmp -
<td>DOWN</td> <td>host:port <a title="debug" href="URI">[I]</a> <a title="debugger" href="http://host:1port/debug">[D]</a> <a title="browse" href="http://host/corp/java/browse.jsp/wa/viewService?serviceUrl=http%3A//host%3A8000/java/Service.jsp/ww&serviceUrl=http%3A//host%3A1port/service/lib">[TB]</a></td>
Thanks
Allan.

Maybe I'm missing something. but showing *both* the input *and* the desired output would be more helpful than what you offered thus far.
