I have few logs files in my
machineB under this directory
/opt/ptd/Logs/ as shown below - My logs files are pretty big.
david@machineB:/opt/ptd/Logs$ ls -lt
-rw-r--r-- 1 david david 49651720 Oct 11 16:23 ptd.log
-rw-r--r-- 1 david david 104857728 Oct 10 07:55 ptd.log.1
-rw-r--r-- 1 david david 104857726 Oct 10 07:50 ptd.log.2
I am trying to write a generic shell script which should try to parse all my log file in
machineB for a particular pattern and print the line which has those patterns. I will be running my below shell script from
machineA which has all the ssh keys setup everything meaning I need to remotely grep on the logs files on machineB from machineA.
# now grep on the various log file for above words and print out the lines accordingly
Meaning, I will have words separated by comma in
wordsToInclude variable - If my logs contain
hello word then print out that line, also print out the line which contains
animal word. Similarly with
And also I will have words separated by comma in
wordsToExclude variable - If any of the lines contains those words then don't print out those line.
I am going with the above format for now for storing the words but any better format is fine to me. I can have long list of words in
wordsToExclude variable so that's why I am going with storing them in those variables.
I know how to do a grep on small set of variables. If I need to do grep from the command line directly on machineB, then I will do it like this -
grep -E 'hello|animal|atttribute|metadata' ptd.log | grep -v 'timeout'
But I am not sure how do I combine this in my shell script so that I can do a remote ssh grep on machineB from machineA.
