I want to use mutt in order to send some files as attached files using the mutt pogram.

I've tried:


mutt -s "Some Subject" -a file1 -a file2 panos1962@gmail.com <message

to send the...

Thank you zaxxon!
We're using RedHat.
Output of uname -a is:

We've not installed any patches since the systme creation (about 3 years).

Hi all!
After killing some processes, I encounter the following problem:

1) some delay in the login process
2) question marks (?) in who output
3) when doing ps -fu for users with question mark...

Dera friend, I've also encountered the same problems in the past. I'm using the "n" qualifier for numeric fields to avoid such problems. Your example, though, has a dark point: you want numerical...

Hi!
You called system("...") in your C program. First of all, the returned value has to do with the exit status of the program run under system, not the output of the command!

Second: Every...

If anyone is interesting in using awk with MySQL databases, then I have some good news:

I've developed a (shared) library, namely libspawk.so, using MySQL C API and GNU awk's extension feature. If...

What is the difference between these two (shared) libraries? Does the _r means something?
Thanks!

Correction!
-----------
The libarries are libmysqlclient.so and libmysqlclient_r.so.

No, use awk

BEGIN {
FS = ","
tmp1 = "/tmp/" PROCINFO["pid"] ".1"
tmp2 = "/tmp/" PROCINFO["pid"] ".2"
}

{
if (another_line) {
printf "," >>tmp1
printf "," >>tmp2
}
...

Are you sure that the mysqldump program exits with non xero value where things go wrong?

Leave a space after between if and bracket too!

if [ $? -ne 0 ]; then

You must use spaces in brackets:

if [ $? -ne 0 ]; then

It's not a complete answer, but it works:

sort -k1n -k2n file

The expression "/X/..." is not what you think. The pattern matching /X/ means that the input line matches literaly X, e.g. sdgasXhasgdasXdfsdf, not the value of variable X. If you intend to math the...

I don't think that another shell is a good idea. I believe that the strength of the UNIX os is among other things its simplicity. After almost 30 years there is a dozen of shells and this is no good...

You can't exclude root user from anything. The only thing you can do is cryptography but yoy'll need to provide some keys every time.

In vi/vim:

:g/abc/s//[Control-V][Control-\]/g
:g/[^[Control-V][Control-\]]/\*/g
:g/[Control-V][Control-\]/s//abc/g

I'm using [Control-V][Control-\] to replace 'abc' pattern with 034 octal...

The only thing you have to do is check the ${connect1} value before printing it:

if [ -n "${connect1}" ]; then
echo "${connect1}"
else
echo "No rows returned"
fi


instead of just:...

There is another solution to this problem, but you have to add some code to your `myscript.sh'. Put some kind of lock while your program is runing, e.g. if your program is a shell script, you can add...

I send you an attached file with the awk source of a simple function for rounding numbers in any scale. Of course there are some limits, but you can edit the code and make it better (if you can)....

Try -- to sign end of options. This is a general rule for such problems, e.g.
To grep -3 try:

grep -- -3 ...

If yoy want to remove a file named -panos you give:

rm -- -panos

etc.

Actually this is a pipeline consisting of two components (mysqldump and gzip). The success of this pipeline depends in the success of the two programs; either mysqldump may fail or gzip (or both...

Of course there is a way to find files of any time interval old.
You can touch a file with certain timestamp (see manual pages for program touch) and then use find with option -newer (see manual...

What do you mean with "count values"?

I think that you found a good solution to your problem. But there is a small bug: ls must be called wirth -A option.
