Hi,
   How can I make a file zero length without deleting the contents of
   the file manually through an editor ?

You can make a file zero length by cat > foo and by typing CTRL-D

Re: File size (shortest possible solution) + don't touch

[Stephen Samuel]

the shortest possible:
       ` > somefile `
(( redirect the output of no command at all to somefile ))

Although not necessary, I'll often go
       ` true > somefile `
True does nothing other than return success. The reason why
I like using it is that it makes a placeholder so that a reader
knows that something (or rather explicitly nothing) is happening.


`Touch` doesn't work.. If the file already exists, it will simply
change the last mod-time. without altering the contents

The original purpose of touch (I think) was to convince make(1) that
something needed to be done.

touch changes the timestamp if the file exists. It sounds like the file
already exists. btw, You don't need to delete it through an editor, "rm
foo ; touch foo" would do it, too. ;-)

Re: File size

[Aroop MP]

How can i attach one file on the top of another file.

Suppose file1 has 10 lines and file2 has 20 lines. I want to attach the 10 
lines of file1 to file2 so that the file2 will have 30 lines in total.

Re: File size

To append file1 to file2 do:
cat file1 >> file2

Simple way to empty a file or make an empty file (bash or
ksh) do:
> file

LMAO

If you are trying to get answers to a test or have us do your home work
for you, this is probably not the best place to do it.  Here you will find
SysAdmins, not all are schooled and many times you will find answers here
that do not agree with your school book.

For stuff like this you should try linux-newbie@vger.kernel.org

Although, you may find a lot of bored SysAdmins here, giving you all kinds
of strange answers (some that are even wrong), this is not the appropriate
place.  As funny as it is, people should not give wrong answers, and less
then knowlegdeable SysAdmins should not either.

BTW, "cp /dev/null > myFile" works, but may need to be contested to give
you accurate points on a test.  Depending on your shell, probably, a
simple ">myFile" will be the proper response.

After we've helped you with your homework, do we get to put our hand up
your sweater?

Re: File size

[Anindya Mozumdar]

Hi,
  Thanks very much for your replies. However, this was not any homework
  or assignment. This arose mainly from an argument regarding touch with
  a fellow linux user, and since we did not have access to any machine
  running linux, the best solution was this mail.

  In fact, someone did give a wrong solution with touch, which was
  precisely the point of argument. The mail was sent in the form below
  so that we can get to know the other unnoticed  ways, hoping that someone
  mentions touch as a solution.
Anindya.

ausearch

[Pittigher, Raymond - CS]

I see that the -w or --word switch was added to the ausearch but how it it used? The man pages claim:

String  based  matches  must match the whole word.

But I have been trying

ausearch -w failed and variation of that but only get the message

ausearch -if audit.log.3 -w failed
failed is an unsupported option

It is used in addition to other matching. If you were to try this search:

ausearch --start today -f va

it will match any file that has va anywhere in it - for example /var/run would 
match. But if you change it to this:

ausearch --start today  -f va   -w

now, /var/run would no longer match. It would insist on the whole file path to 
be va.


> But I have been trying

You would just use  "ausearch -sv no" to find failed records. Some search 
options do not do partial matches. The -w option does not take an argument.

file size

Is there a file size limit on the audit.log file? The logging seems to
stop at 2147483647 bytes.
