[SOLVED] Confused about a Linux Tutorial on Security

hexaferrum · 10-15-2015, 04:35 AM

Hello Forum:

I like to practice the recommendations on Linux Tutorial forum. Nevertheless, I came across with a tutorial about security here http://www.linuxquestions.org/linux/...uick_find_Tips Beyond the commands, what is the intention of this tutorial for?
I tried it and with the first command string, the command stop with this response:

Code:

grep: ./.lastpass/pipes: Is a directory

and then, I just need to Control+C to get out of it.
Thanks for all you do!

Well, I had a quick look at the tutorial, and the intent seems to be that there are some commands which could be useful, if you are looking for files with certain characteristics. One example might be if you had a suspicion that you had been hacked (alternatively, you were taking a preventative approach, and were looking 'just in case') you might be looking for surprising files that were executable, on your system.

The message says what is wrong. You only can grep files, not directories. Add "-type f" to the options for the find command and it will only search files.

I don't think you needed to Ctrl+C, the command just didn't finish yet. Depending on the amount of files the command fill take some time.

Thanks for the information and clarification. It was helpful.

grep itself has a recursive option -r which you could use instead of starting with 'find'. ime its smart enough to skip dirs in this situation.
