Hi Team,

I am using one script, It is working fine, the problem is it gives unwanted telnet errors when I am using it.  
I just want to remove these unwanted errors/info from my screen.

```nohighlight
bash-3.00$ cat raza_site_temp
#!/usr/bin/bash
#rj835b
IFS="|"
REGEX="$*"
echo
snarf2 -c "show chassis status" `showHosts gsx |egrep "$REGEX"` > /dev/null > d1d1
echo
cat d1d1 |egrep -i "Node|Temp"|sed '/Node/{x;p;x;}'
echo
echo
echo "GSX Temperature > 30C"
echo " *********************"
echo
cat d1d1|egrep "Node|Temp"|awk '{if ($1~/Node:/) print $1,$2; else if ($1~/Temperature/) print $0}'|sed '$!N;s/\n/ /'|awk '{if (substr($4,1,2)>30) print $2,"----->", $4}'|awk '{printf "%-10s %s %s\n", $1,$2,$3}'
echo
bash-3.00$

```

Output of the script

```nohighlight
bash-3.00$ ./raza_site_temp hst

When I fire script it will ask for password, then it will fetch data from different node, error coming from redundant ports.  
I jus want these telnet and connection refused error does not appear on my screen.

Thanks  
Raza

[s]You need to redirect STDERR to /dev/null as well to avoid these messages (unless inability to contact a host is of interest 😉 ), we can do this by redirecting stderr to stdout `2>&1` this is a very common idiom.

````nohighlight
snarf2 -c "show chassis status" `showHosts gsx |egrep "$REGEX"` > /dev/null > d1d1 2>&1
```[/s]

Duplicate thread... answered on the better formatted one.
