To see the output from program, you have to print the output. I believe stdout is used internally for this function:-

print subprocess.check_output(shlex.split(command))

No shifts necessary...
for hostname in "$@"
do ping "$hostname"
done

Yes. It works this way because you are reading a file (sequentially) and processing it as it comes.

if you find red, process that
if you find blue, process that

Yields the same results as

Hi,

ssh normally will not forward X!

Try


ssh -X oracle@localhost


Regards,

xabbu

ssh oracle@localhost works but can create a problem with known_hosts in a shared home directory.
Try the ssh method first, before you try the xhost,sudo method!

The xhost + only works if the display still works i.e. before the su or sudo. And it opens your display for everyone until you do xhost -.
Instead of su|sudo+xhost maybe you can do ssh that normally...

man bash:

So - the EOF string needs to be on a line of its own. As does the word man, btw.

Hi,

You should be able to find most of the information using "openssl" for the exact syntax and all the switches run,

In the basic regular expression specifying the search pattern in the sed substitute command:

\1 in the replacement string in the sed substitute command is replaced by the set of characters matched by expression in the 1st \(expression\) in the basic regular expression used in the sed...

Change any input line that matches:

Look at this link (http://search.cpan.org/~gaas/libwww-perl-6.05/lib/LWP/UserAgent.pm#Proxy_attributes).

From what I know, there is no sub-routine 'site' in the LWP::UserAgent module, available in CPAN. Are you using a custom built variant of this module?

$tz is a reference variable that refers to the object obtained by blessing some package. site is a sub-routine (object method) in that package to which you're sending two arguments (as a list) viz....

Technically, the -> is a binary infix dereference operator. In your case, since the right side of the operator is neither an array/hash subscript nor a subroutine argument list, it implies a method...

First, I know almost no perl, but that never stops me!

-> is stolen from C, says point to a child member of, in this case a member function or method of a class/object/struct type.

True. The other plausible explanation is that the writer of this intended to search a file named "server.log" for a string/regexp he just forgot to write. This would mean the statement is equally...

Looks like a hack to print all lines after and including the first to match 'server.log' and then count those with Option=[Yes]. It assumes that the number of lines left in the file will be less than...

Sure. The right dot means "any single character", and * means "zero or more of preceding thing". So .* means "zero or more of any character". And each of the zero or more can be a different...

Yes. On each line, sed deletes (substitutes nothing for) the leftmost dot (period) and the remainder of the line.

i=$( grep Multiple "test.`date +%Y%m%d`-${hour}3101.txt" )
The curly brace form is unambiguous as the variable name is clearly delimited.

echo 'Wed Apr 3 10:39:30 EDT 2013' | awk -F'[ :]' '{print $4}'
date +%H

You can simply run date with format control to get hour:
date +%H

Use command substitution (http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_06_03) $(..)
hour=$(date +%H -d "1 hour ago")
