Homework & Coursework Questions

I'm using putty in wndows 7

Code:

find ~/UnixCourse -type f -name "*.txt" -print

shows me all the text files and when i add

Code:

-exec head -n1 {} \;

it shows the first line underneath. however, when i try it within the hw assignment on the same program i get this:

Code:

find 'head' terminated by signal 13
head: error reading '../fileAsst/TweedleDee/hatters.txt': is a directory

and it says that for every text file within UnixCourse and all its sub directories. I can't understand why i get a different output.

You're mistaking the TV for the channel, PUTTY is not UNIX, PUTTY is just a terminal emulator used to talk to other systems.

If you don't know what your system is, you should find out because it's important. uname -a

ok my bad.
linux atria 2.6.38-8-server #42-Ubuntu SMP Mon Apr 11 03:49:04 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

when i try it within the hw assignment
Please post the script you ran which produced the error messages.


Ps. Does my script in post #3 run on your system and produce the desired result?
(It will tell us a lot about your local system).

the first code you posted didn't work, but your second i just added

Code:

-exec -head -n1 {} \;

and it worked. they way we're supposed to do the assignment is we have two sessions of putty up on the same server. on one it has a question that we have to provide code to answer. on the other, we try out code to answer the question. so the script is

Code:

find ~/UnixCourse -type f -name "*.txt" -print -exec -head -n1 {} \;

when i execute it, it gives me (or at least i think it gives me) the desired output, but when i execute in the assignment in the same program it gives me the error message.
