UNIX for Dummies Questions & Answers

Hi,

Here is my problem:

I try to write a script to find data in a file named "data" for exemple.
Let's say I am in the directory /x/y/z, there are several sub-directories in the "z" directory (each sub-directory has a file "data") and I am searching for the word "help".
So I use this command to search my data:

find /x/y/z -type f -name data -exec grep "help" {} +

It works, but how can I search for the word "help" in the most recent files "data".
I try with the command "-newer" but it did not work

Please, can somebody help me?

Thanks

you can get the most recent files by doing

Code:

ls -lart /some/directory/name/

so maybe try something like

Code:

ls -lart /some/directory/name/ | find -some -fancy -find -flags

Thanks for your answer, but I don't know how to use this code:

Code:

ls -lart /some/directory/name/ | find -some -fancy -find -flags

with this one:

Code:

find /x/y/z -type f -name data -exec grep  "help" {} +

Code:

 find -mtime <some time> -exec grep "help" {} \;

You can, to a certain degree, limit the search space with the -mtime option. Eg '-mtime -1' would mean files modified during the last 24 hours. With -newer you'd have to have a reference file that times could be compared against. Such a file can be created using touch and an appropriate timestamp.

Thanks for the answers, I think mtime is not a solution for my case, since I write a script for general cases, so I think -newer has to be the solution.
Concerning the touch command, this is a nice idea, but how can I use the find command to find every files I need, and then using touch to gather all my files?

This is for example.If you want to execute some command for the matched files.You try this.

Code:

 find -type f -exec touch {} \;
