Script to search every file in a directory and print last few lines
Hi everyone,

I need to write a script to search a directory, output the name of a file to an ouput file and print the last few lines of the files to the output file such that I would have something like this:

Code:
FILE1:
LINE
LINE 
LINE

FILE2:
LINE 
LINE
LINE

FILE3:
LINE
LINE 
LINE

Any ideas?

Mod Comment Please use CODE tags as required by forum rules!
In this case, it would have helped tremendously as it would show if you're talking of one single output file or three files...

Hi,

Did you mean like this ?
I have a few files and each file has 5 lines for example.

Code:
find . -type f -print -exec tail -3 {} \;

Gives output:
Quote:
./f1
3
4
5
./f3
33
34
35
./f2
23
24
25

To add a blank line between them, you could add another -exec clause to the find like this:-
Code:
find . -type f -print -exec tail -3 {} \; -exec echo \;

If you want file names to have a trailing colon : then it becomes a little more convoluted:-
Code:
find . -type f -exec echo "{}:" \; -exec tail -3 {} \; -exec echo \;



I hope that this helps,
Robin
