Shell Script to List Node Definitions

[Colloid Snake]

Hello everyone-

I am working on a shell script to parse out a Node.def file that contains the hostname, version, IP address, and date updated. There is a separate .def file for each node (of which there are several hundred), and each node is in a separate directory.

I am attempting to extract the node name and IP address from each .def file and compile these into a single file, but I'm getting an error, no matter what I alter, so I think I'm just not setting this up properly. Can anyone help?

echo "`date` - List of names and correlating IPs for `hostname`" > SensorList.txt
 
set file_list = `find . -name "*.def" -type f`
 
for $file in file_list 
   # extract name and ip from file
do
   `cat $file | grep "NAME=*"` >> SensorList.txt
   `cat $file | grep "IP=*"` >> SensorList.txt
done
 

Error:
# ./CreateSensorList.sh
./CreateSensorList.sh: file_list: command not found
cat: file_list: No such file or directory
cat: file_list: No such file or directory

I have attempted to move around the `` to encompass different things, add/remove the $ in the for, etc... And I'm currently out of ideas, so any help would be appreciated.

please have a look at following script..it should work

 
echo "`date` - List of names and correlating IPs for `hostname`" > SensorList.txt
file_list=`find . -name "*.def" -type f`
for file in $file_list
# extract name and ip from file
do
  echo $file
  `cat $file | grep "NAME=*"` >> SensorList.txt
  `cat $file | grep "IP=*"` >> SensorList.txt
done
 
 

check out the second line.
you don't have to use 'set' to initialize the local variable..it is used to set the environmental variables.
Don't put spaces before and after '=' operator.
In third line use '$file_list' instead 'file_list'

Rest is fine.....

Ah, thank you very much! I also removed both of the `` around the cat $file... lines to get it to run (and the ='s are in search strings, that's how the file is set up so I left those in) and it's working now.

Thanks again
