I was trying to develop a script that would do nslookup using both name and ip of server and format the output and store in an output file. Please find the script below.
Code:
#!/usr/bin/ksh
cat $1 | tr "[:upper:]" "[:lower:]" |
while read ip name
do
ERROR="$(nslookup $ip | grep can't | awk -F" " '{print $5}' > /dev/null 2>/dev/null;echo $?)"
if [[ $ERROR -eq 0 ]]
then
FQDN=`nslookup $name.symc | grep Name | awk '{print $2}'`
echo $ip $FQDN $name >> $1.hosts
else
FQDN=`nslookup $ip | grep Name | awk '{print $2}'`
echo $ip $FQDN $name >> $1.hosts
fi
done
I would be running the script by providing filename as argument. The content of filename would be in format <ip address> <host name>.
While I execute the script, it throws error... (pfb)
Code:
# ./dnsscript test
./dnsscript: syntax error at line 25 : `'' unmatched
The 25th line is
Code:
FQDN=`nslookup $ip | grep Name | awk '{print $2}'`
Could you please help me to get this script running perfectly ?
Many Thanks,
Praveen

zegrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
