Sed Command

Hi,

I am trying to remove the Column from .CSV using Awk Command. Below is the input

Name,Age,Description,Location
Gopal,32,Tech Lead,"Ramnagar, Naintal"
Gaurav,24,"Linux Admin, Expert","Noda"

I want column 1,2,4 and i am using below mention command

awk -F, ' BEGIN { OFS="," }
{
print $1,$2,$4
}' new.csv > new-done.csv


but instead of getting Gaurav,24,Noda

i am getting

Name,Age,Location
Gopal,32,"Ramnagar
Gaurav,24, Expert"

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";

What I did in windows was create images of my drive and restore them.

in linux I am running

Code:

rsync -aAXv --exclude={"/home/*","/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} /* /path/to/backup/folder

and this creates a folder for me with all my files, and apparently saves meta data like permissions and paths...

Since I'm using arch and things break sometimes,I'm booted into a CLI with errors and cannot figure my way out since I'm a noob... would I be able to just delete my entire root and replace it with the rsync backup without a problem?

Hi!

Here is mine configuration and I want make it show unicode(russian) in console, it works perfect in X11 but not when I logging into tty.

vconsole.conf
Code:

LOCALE="en_US.UTF-8"
KEYMAP="sv-latin1"
FONT_UNIMAP="lat1"
FONT_MAP="ISO8859-1"
CONSOLEFONT="ruscii_8x8"
HARDWARECLOCK="localtime"
TIMEZONE="Europe/Stockholm"
USECOLOR="yes"

I just installed Redhat 7 and try to config the network , add the IP address to network card , but I got the problem.

I modify the file /etc/sysconfig/network-scripts/ifcfg-enp0s3 , the configuration is as below , and then reboot .

DEVICE="enp0s3"
NETBOOT="yes"
HWADDR="08:00:27:15:38:B7"
TYPE="Ethernet"
BOOTPROTO="none"
NAME="enp0s3"
UUID="462f4834-4fe7-43a7-84e7-83b2722e94c1"
ONBOOT="yes"
IPADDR="192.168.1.1"
NETMASK="255.255.255.0"

After reboot , I use "ip addr show" still not shown the ip address , the ip address is still blank , would advise what is wrong ? thanks

Hi all ,
I have a requirement where I have a file. Contents of the file are :
#comments
VAR="abg"
RES=123
#comments
IC6790ABG="https://www.abc.com"
IC5678-vg="https://www.bhy.com"
IC-gy_567:78="https://www.gyt.com"
#comments
The variable names can not have characters like - , : so
in this file I have to find words starting with IC and replace characters like - ,:
I want to change only the variable name , not the whole line.
I have used SED command

sed -i '/^IC/s/[^0-9 a-z A-Z _]*//g' file

when I am using this command , it is replacing the whole line
output becomes :

#comments
VAR="abg"
RES=123
#comments
IC6790ABGhttpswwwabccom
IC5678vghttpswwwbhycom
ICgy56778httpswwwgytcom
#comments


But I want the output like this :

#comments
VAR="abg"
RES=123
#comments
IC6790ABG="https://www.abc.com"
IC5678vg="https://www.bhy.com"
ICgy_56778="https://www.gyt.com"
#comments

How can I get the desired output , thanks for your help in advance .

Hello,

They gave me this:
Code:

#!/bin/bash

# Write error message on stderr and die
function die() {
  echo "$@" >&2
  exit 1
}

# Load var from properties files
function load() {
  for propertie in "$@" ; do
    [[ -f "${propertie}" ]] || die "load() : \"${propertie}\" don't exist !"
    while read ; do
echo "${REPLY%=*}"
echo "${REPLY#*=}"
      [[ -n "${REPLY%%=*}" && -z "${REPLY#*=}" ]] || die "load() : Variable \"${REPLY%%=*}\" is empty!"
      eval "${REPLY%%=*}"=\'"${REPLY#*=}"\'
    done < "${propertie}"
  done
}

load "manage_srcds.conf"
echo "SRCDS_TICKRATE=$SRCDS_TICKRATE"
echo "SRCDS_SCREEN=$SRCDS_SCREEN"
echo "SRCDS_SRCDS_GAME_NAME=$SRCDS_GAME_NAME"
echo "SRCDS_MAXPLAYERS=$SRCDS_MAXPLAYERS"

but, return:
Quote:
###################################################
###################################################
load() : Variable "###################################################" is empty!

cat manage_srcds.conf

I just wish that there was no empty variable excluding those who do not have integer.

Best regards,
