*** ERROR: PERL Module Apache::DBI Is Not Installed !

HI all,
I'm writing a perl script to automate VM UUID transformation into a format used by our ServiceNow CMDB/discovery.

Anyone know which perl module to include to use the string length function?

Alternately, how would I determine which perl modules exist that are available to include, vs. which functions each module contains?

thanks in advance,

Hello,

I need to install perl-Expect, so, I executed:

Code:

#  yum install -y perl-Expect
Error: Package: perl-Expect-1.21-14.el7.noarch (epel)
           Requires: perl(IO::Pty) >= 1.03
Error: Package: perl-Expect-1.21-14.el7.noarch (epel)
           Requires: perl(IO::Tty)

Okay, I need to install perl(IO::Pty)

I launched
Code:

# yum install -y "perl(IO::Pty)"
No package perl(IO::Pty) available.
Error: Nothing to do

So, how to install all required perl modules to the RHEL?

Hi All,

I have perl script which I am trying to run on 1st Monday via cron job.
So I scheduled it as follows:

0 0 1-7 * * root ["$(date '+%a')" = "Mon"] && /usr/bin/perl script.pl

But then it didn't run so checked cron log and it seemed like its missing the command. so added a \ in front of %a and then it picked up the whole command as per cron log.

But still it didnt ran the script. I then change the script to just && echo "test">/tmp/test

Still nothing. if I run it as /usr/bin/perl script.pl it runs though

Thanks in advance.

I have a little bash script that cats out a file and tells me if there is a line
where the 11th column has more than 6 characters in it.
It emails me where there is a bad line in a file - bead meaning that it will break a
donwstream process.

anyhow when i get the email saying that there is a bad file i just log in to the pc via
vpn and the I sed out the lines from the file that I get in the email. The bad lines are
always in danny.csv not danny1.csv
It has been the same lines killing the downstream process for a few weeks, so i put the "sed -i's" into
the script and it does it automagically.

[CODE]
for i in danny.csv danny1.csv
do
cat /come/and/play/with/$i | perl -ne 'print if length((split /,/)[10]) > 6' | mail -s "danny.csv bad line" casper@casperr.com
done

#it would be nice to find a perl change the file in place
sed -i '/D,642,0642,UBF,EVL,,M,,S,S,FOREVER,213,213,/d' /come/and/play/with/us/danny.csv
sed -i '/D,642,0642,UBF,EVL,,M,,S,S,QSP-U=C,4,4,/d' /come/and/play/with/us/danny.csv
[CODE]

However when a new line gets put into this file, I am going to have to log in and take out the line.
SO I have been trying to write a perl one liner that will edit the file in place, like sed, and make a
backup of the file. I just need a perl one liner that will delete any line where the 11th columns has more
than 6 characters in it.
[CODE]
perl -p -i.bak -e 's/\,\w{7}\,//g - which does not work.
[CODE]
I tried something like this:

[CODE]
perl -nle 'print if /\,\w{7}\,/' /come/and/play/with/us/danny.csv
[CODE]
but that does not catch the QSP-U=C and it catches more lines than just the
FOREVER. for a solutinog I need to focus on the the 11th column.

Hi All,

I'm not a perl programmer, so please help me to disable warning messages. I tried like commenting 'use strict' and 'use warning' in perl program. But it is not working.

All I want is to disable warning messages.

Please note its not actual ping program, But a perl wrapper for ping to display ping output in color (Cope).

Below is output:

Code:

$ ./ping google.com

Hello,
the "lsmod" give the list of the loaded modules/drivers.
How to know when was theier loading time (start/end) ?
Is there any existing log file where that information can be seen ?
For another topic, see http://www.linuxquestions.org/questi...ml#post5362257, I am thinking the unfinished loading of a specific module (ehci-pci or other pci driver) or the loading of a module before another one, could disturb the loading of a module e1000e during a cold boot.
Thanks a lot for any help.

Something else?

OK,

Lastnight I decided to finally attempt to install the dedicated ATI/AMD Catylist drivers. After all I was successfull with the HP drivers, right...

No matter which grub selection I make, getting in is broken, except of course for the Windows XP Pro x64 entry, that works just fine. I'm here with you today, because of the Fedora 21 Live DVD, (slooooww).

Here is the drivers log file:

==========================================================

I just rebooted without attempting to configure the card, as per the ATI/AMD warning stating that it's important to do so, because my thinking was derailed due to seeing errors, and the install program said I needed to reboot. Afterall, I just couln't believe that with a "Failed to compile kernel module" error, it would actually keep the changes I'd made, that surely Linux had a failsafe in place for such circumstances. In other words, I'm also a newbie, and just don't know how many hoops of fire one has to jump through to be at peace with linux.

Can anyone please help be get back into my install, I've already set up so many things, there's just got to be a way, right?


Thanks in Advance!

Hello, I'm trying to get bumblebee to work running Ubuntu 15.04.
I've followed this guide to get to the point I am now, but I'm getting an error that I couldn't even google the way out of it.

This is what I get from demencia@demencia-laptop:~$ primusrun glxinfo | grep OpenGL


primus: fatal: Bumblebee daemon reported: error: [XORG] (EE) Failed to load module "mouse" (module does not exist, 0)

But I was told that that error is not really important that I should have a look at my /var/log/Xorg.8.log, where I found my dead end.

Here's my /var/log/Xorg.8.log
file.

Any ideas?

I am currently running a system simulation on multiple files.
I have a computer algorithm written in perl to run "system" simulations for all the files I need

What I am trying to do is put multiple files into one file, only problem is that its not doing exactly what I need it do

Example:

I am "cat txt0.txt txt1.txt txt2.txt txt3.txt > allfiles.txt"

I need it to read as

txt0.txt
txt1.txt
txt2.txt
txt3.txt

Instead its taking all the files and taking the information within each txt file and putting them all together. Info that looks like this


fdfasdfqwdefdfefdkfkkkkkkkkkkkkkkkfsdfasdxfewqfe..........

all clustered together

you get the picture ?

I am really confused how to get this to work, there are over 100 files that need to go into a single file.
That way when I run it through the perl algorithm I created, I can do it in one shot.
