Shell Programming and Scripting

from where you will get the matching keyword? or those static?

Code:

 
grep -e "pattern1|pattern2" will search for multiple patterns!

The keywords will be static and defined in the script. The output I've quoted earlier will be generated by some command which I call in my script and I want to be able to capture and parse the output for certain keywords. Then if I do have a keyword match, I want the script to quit and present the matched lines. I think grep only does one keyword at a time? I want my output to look like this (assuming there's a match for all instances of bar1.txt files and directories named 'foo'):

I did not get you fully!!!

Please post a sample input and output you are expecting along with the sample keywords.

Sorry for not being clear! Here's the sample run of an external command which I need to call within my script and its output:

When I run this command in my script, I want to be able to parse the output above for keywords which I also define in the script, such as "bar.txt", "foo/", etc. If there's a match, then I want my script to say something like this:

I tried to use this perl command as a parsing mechanism, but if I have a keyword that looks like "directory/file" then perl complains and I'm not sure how to escape the slash.

Code:

cat command_output.txt | perl -ne "exit 1 if ( /keyword1/ || /directory/keyword2/ || /XXXXXXXXXXXXXXXXX/ );" ; echo $?

Basically I want my script to look something like this:

Code:

external command | awk 'parse output for keywords'
if matches found
then
     print matched lines
     exit 1
else
     echo "no matches found"
