Hi,

I need to create a script to read the files in the specific folder, and looking into line by line, for example, a keyword: IP or a specific the IP 100.100.100.100 - not IPX is not valid, neither XIP - blank before and after is important to reduce the amount of records found. If I find it, I need to create a new file with the filename and the line where it was found the keyword.

Example:

Folder: /home/user1/tstfile
files in this folder:
filenumber1
filenumber2
filenumber3

supposing that the keyword was found in the filenumber1. I need to create a new file - for example: found.txt, where in this file we will be able to find it.

filenumber1 120.222.110.20

or for other files

filenumber2 IP
filenumber3 192.168.168.0

and so on.

Does anyone can help me? tks.

Never done it myself, but this thread from another forum might help get you started: http://stackoverflow.com/questions/3...tern-in-a-file

Please show what you have attempted and where you are stuck? You may also wish to advise what language you are going to be writing this script in?

Hi,

I don’t have much to show you. I didn’t find a command to list only the files, not the directories, besides this, I also don’t have enough knowledge.

#!/bin/bash

## I need to receive as parameter $1, the directory to read and check the files

## One idea is to save the list of the files

## The command below is not correct – I was not able to find a command to list only files

ls –la > `$(mktemp)`

filename=$mktemp

while IFS='' read -r line || [[ -n "$line" ]]; do

## I get the name of each file in the directory
## For each file, I need to read line by line as well and check the string

while IFS='' read -r line || [[ -n "$linetosearch" ]]; do

## The line below is not correct; it should have the consistence to find the strings:
## IP (blank before and after, 192.168.168.10 (specific IP), and other strings.

## If it is found, a new file would be saved with file and the linetosearch

$filename $linetosearch >> $2

## $2 the second parameter where there is the filename to be saved.

Done < $line

done < $filename


Tks.

Perhaps grep can do what you want. Something like:
will look in all files in the current directory and subdirectories for either the string 'IP ' or the string '192.168.168.10' and print the filename, linenumber and the actual line. Redirect the output of the command to a file by adding ' > output.txt' if it does what you want.

Assuming we are only reading the single level of the directory, create a for loop to read all objects in the directory and perform an if to test if object is a file, then simply grep the data you need.
