someone once told me that use can pass a file to grep and use that to search the contents of another file. if that is the case I'm not entirely sure why the following isn't working for me.
Code:
[root@LCENT01:~]#grep -i id_rsa.pub .ssh/authorized_keys
[root@LCENT01:~]#cat id_rsa.pub >> .ssh/authorized_keys
[root@LCENT01:~]#grep -i id_rsa.pub .ssh/authorized_keys
I am attempting to grep the contents of a key file I have SCP'd to a remote server. I am able to cat it:
Code:
[bluethundr@LBSD2:~]$:ssh root@sum1 cat /root/id_rsa.pub
root@lcent01.summitnjhome.com's password:

I would like to know how I can replace a string in one file with the complete contents of another life.

I want to be able to check the contents of a text file for a specific string and remove it from the file from the command prompt. I would basically be searching through a number of files and if a specific string is found I would like it removed automatically. pretty much a find and replace, were the replace is nothing. any one got any ideas on how you would do this. I already have the search part sorted just need to be able to remove the string I don't want from the multiple files.

Let me *try* and explain what I'm trying to do, and keep in mind aside from a little command line stuff I'm a beginner to any of what I'm asking about.
I have a directory structure something like this:

2.chatlog

So that whatever was captured in the () in the first part of the statement would be used in the 1 in the back part of the statement for every n.chatlog that might be in any of the /webserver directories at that time.

When I type in the command directly, without using an inbetween variable, it works fine.
I would like to write a newline delimeted rules file using PCREs for use with the grep command. Grep has the option -f to obtain the search pattern from a file, and option -P to search using PCREs. However, these two options do not work together. The -f option only seems to work with fixed string rules.A friend previously helped me get around this limitation somehow, but I can't remember how he did it. I also would like the ability to add comments at the end of each rule in the file.

View 1 Replies View RelatedAs the topic title states, I would like to know the preferred way of viewing the contents of a Berkeley DB file. The machine the file is on is running SuSE 9.3, with perl 5.8.6 and php 5.2.0 installed. (I'm not sure if stating that was necessary, but my understanding is that the more information I can provide you, the better. The purpose to this question is this: I have been requested to look into coming up with some form of Geocoding software for one of my company's clients. Specifically, I've been requested to look into trying to obtain Census tract/block information.
I discovered the Perl module Geo::Coder::US, which uses Census input (TIGERLine files) to create a Berkeley DB file, then reads said file to produce its own output. However, the output from Geo::Coder::US only provides latitude and longitude information.At the moment, my only interest is in popping the Berkeley DB file generated with the import script packaged with the Geo::Coder::US module. I'm trying to see what the contents of that DB file are, so I can determine if the information I'm after is even in there in the first place.
