How I Can Print A Specific Range Of Nubers Form A File.

when i am running delay.awk file on AODV.tr and LAR.tr For AODV.tr , it is giving me the o/p value as some delay
but for LAR , its showing me the follwing error

gawk: e2edelay.awk:93: (FILENAME=larscen5.tr FNR=36516130) fatal: division by zero attempted

I was unable to recify the error. could you please help me.
thank you so much

this is the code of awk file which i am using for calculation of delay. kindly help

hello all,

please help me with python ftplib. i was trying to copy files from my linux machine to a windows server using ftplib. everything was working good. but i'm only able to copy files from the same directory the script is. how do i copy files from a different directory? i always get "file not found error message". here's my code :

Code:

tester_name = str (socket.gethostname())
def upload(ftp, file):
    ext = os.path.splitext(file)[1]
    if ext in (".txt", ".htm", ".html"):
        ftp.storlines("STOR " + file, open(file))
    else:
        ftp.storbinary("STOR " + file, open(file, "rb"), 1024)



parse_source_path = ('/path/to/where/i/go/')
parse_source_file_list = os.listdir(parse_source_path)

ftp = ftplib.FTP("server_IP")
ftp.login("username", "pass")

folder_list = []

ftp.dir(folder_list.append)

if str(tester_name) not in str(folder_list) :
    ftp.mkd("%s"%tester_name)
    ftp.cwd("%s"%tester_name)
    for files in parse_source_file_list :
        print files
        upload(ftp, files)


else :
    print "later"

I am trying to process some .csv files with Linux as follows:

Some fields have data with newline characters embedded, like so:

"Bob Smith
531 Pennsylvania Avenue
Washington, DC"

(I verified the existence of the " via Wordpad. The file is too large to easily edit in Wordpad to get all the data for each row on a single line).

what linux command would I use on the files to get the data in each cell on one line?

I have tried:

1. awk -v RS="" '{gsub (/\n/,"")}1' file > newfile

but the cell data was still being read in as if "531 Pennsylvania Avenue" was a brand new row in the CSV file.

2. Command 1 followed by awk -v RS="" '{gsub (/\r/,"")}1' newfile > finalFile

but that resulted in all of the data in the file being put onto a single line.

3. awk -v RS="" '{gsub (/\r\n/,"")}1' file > newFile

But that result was the same as attempt number 2.

How can I preprocess the file so that:

"Bob Smith
531 Pennsylvania Avenue
Washington, DC"

is read as a single field on a single line as part of the row it should be associated with, like

"Bob Smith 531 Pennsylvania Avenue Washington, DC"

i need to complete this exercise but my code has some issues
HERE is the PRoblem:
Create a script that can accept ANY amount of numbers from the command line. Process the numbers one at a time, where numbers greater than 10 print “large”, numbers less than or equal to 10 print “small”
E.g. process 5 10 15 would print
small
small
large

and here is my code so far
if [ $@ -le "10" ]
then
echo "smaller"
else
echo "bigger"
shift
fi
if [ $@ -le "10" ]
then
echo "smaller"
else
echo "bigger"
shift
fi
if [ $@ -le "10" ]
then
echo "smaller"
else
echo "bigger"
shift
fi
if [ $@ -le "10" ]
then
echo "smaller"
else
echo "bigger"
shift
fi

any help would be greatly appreciated

My DNS Server works fine. Only it cannot make the log.
when I will run this command:
#dig -x 10.40.124.2
the result comes fine but the log is not make in /var/log/queries.log file.
The named is running without chroot enviroment.
Please help me in solving this.

I am using the following two commands to output CPU and RAM usage on a Linux machine.

Code:

/bin/grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}'

/usr/bin/free | grep Mem | awk '{print $3/$2 * 100.0 "%"}'

My problem is that the output is like this

Quote:
5.33672%
13.9723%
Is there a way to output a single number? For example

Quote:
5
13
Thank you

Hi all,

I'm trying to identify files that do not have matches for certain strings. FYI, these are files of DNA sequences and I'm trying to find those that are NOT sampled for any species by my group of interest (e.g., genes that are specific to that group of organisms).

I tried this code but it's actually yielding a list of files that DO match for my regexp.
Code:

for FILENAME in *.fas
do
grep -q -L ">PBAH" $FILENAME && grep -q -L ">SKOW" $FILENAME && grep -q -L ">CGRA" $FILENAME && echo $FILENAME
done

Basically I want to somehow go through and file files that do not contain ">PBAH" ">SKOW" or ">CGRA". Any assistance would be greatly appreciated!

Best,
Kevin

I use following shell script to send email. But the subject of email always shows "This" instead of "This is L_1.R is finished". You may refer http://www.linuxquestions.org/questions/linux-newbie-8/how-to-define-variable-in-%60ssh%60-4175540566/
Code:

host_list=("c15-0330-01.ad.mtu.edu" "c15-0330-02.ad.mtu.edu" "c15-0330-03.ad.mtu.edu" "c15-0330-04.ad.mtu.edu")
program=("L_1" "L_2" "L_3" "L_4")
subject="The job is finished"
ssh -f c15-0330-01.ad.mtu.edu 'echo' "the job ${program[0]} is finished" '|' 'mutt "zwang10@mtu.edu" -s' "This is "${program[0]}".R is finished";

For whatever reason, when I try to mount a data DVD I get the following message:

Unable to mount [disk name]
Error mounting: mount exited with exit code 1: helper failed with:
mount: mount point /media/cdrom does not exist

Yet, if I put a DVD video in I can play on any of my video apps, yet I also can't mount those in a file browser. I have no idea what has caused this. I haven't backed up data to disks in a long time, I only did so today because I'm running low on space in one of my drives.

I was told elsewhere that I needed to alter a file: /etc/udev/rules.d/70-persistent-cd.rules

But I have no idea how to do this, and what I found there does not look like what was shown. This is what my file looks like:

Code:

# This file maintains persistent names for CD/DVD reader and writer devices.
# See udev(7) for syntax.
#
# Entries are automatically added by the 75-cd-aliases-generator.rules
# file; however you are also free to add your own entries provided you
# add the ENV{GENERATED}=1 flag to your own rules as well.
# TSSTcorp_CDDVDW_SH-S223C (pci-0000:00:1f.2-scsi-1:0:1:0)

SUBSYSTEM=="block", ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:1f.2-scsi-1:0:1:0", SYMLINK+="dvdrw", ENV{GENERATED}="1"

Any suggestions would be appreciated.
