Shell Programming and Scripting

Hello:

I need help adding a key word search to my bash script. I have the following script. My boss whats the user to be able to add a search word e.g. unknown failures for the script to search the logs through and find the instances. I had originally done it so it grepped for unknown failures, but now he wants it to accept a key word. Any help is appreciated. Thanks in advance.

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

Did you mean run time search key word?

Get the word and search as variable.

Code:

grep "$search_word_input" filename

Also, there are too many UUOC in the code, take a look at them

Code:

cat /var/log/messages |grep -i '[audit demon stops]'>>/tmp/logproblems.txt
<can_be_written_as>
grep -i '[audit demon stops]' /var/log/messages >> /tmp/logproblems.txt

cat /var/log/messages  |grep -i unknown |wc -l>>/tmp/logproblems.txt
<can_be_written_as>
grep -ic unknown /var/log/messages >> /tmp/logproblems.txt

cat /var/log/secure |grep -i 'password check failed'|awk '{print $0}'
<can_be_written_as>
awk ' /password check failed/ {print $0}' /var/log/secure

This is what I want to do.


Get the word and search as variable.

So that I can have an option in the menu for the person to enter a keyword and do the search on that keyword. I think it needs to be a variable or something like that. I would appreciate any help doing this. Thanks.

I guess that is what I had posted.

Get the input using " read "
and use the above grep

I guess my lack of scripting combined with my flu are making me dizzy. If I add a line to the menu, such that is says input here your search criteria. How then do I pass it to the read?
echo " 6) Input your search criteria here"
6) echo "read"
;;

it's something like :

Code:

echo  "   6) Input your search criteria here" 

read var_1;

;;

grep "$var_1" file_name.txt
