Bash Script For Xfce4 Powermanager Settings Switching Forth And Backward

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";

Hi, I am using a XML file in server location which contains some attributes and value.I just want to replace the attribute value inside the tag keeping the complete line and xml file intact. I am looking for Regular expression which can search for attribute name and replace the attribute value with the provided one. Please find below property details.

<server>
<mbean code="com.xyz.domain.wsmq.WSMQConnectionFactory"

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!

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"

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?

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,

Hi all,

I am trying to write a script that syncs files from source to destination. I have one centralized server that can ssh to any servers without pw. Now when I run the script, it can ssh to source server perfectly fine, but you need to enter password for destination server. Was wondering how I can clean this up before I start using case statements

Below is a sample I wrote

#!/bin/bash

#This scripts syncs shit

echo "Type in ID: "
read ID

echo "Type in Server : " #source server
read S

echo "Type in Destination Server: "
read DS

if [ $S == 9 ]; then
ssh -t "root@"$S"webserver1" "rsync -av /home/rlui/"$ID "root@"$DS"webserver2:/home/rlui/";
ssh -t "root@"$S"webserver1" "rsync -av /home/rlui/tmp/"$ID "root@sl"$DS"webserver2:/home/rlui/tmp/"
exit 1

where S and DS are cluster numbers

I apologize in advance if I am not clear on anything

I've been using this a lot:

find <directory to start search at> -name "<files to search in>" -type f | xargs grep "<string to search for>"

e.g.

find /usr/include -name "*.h" -type f | xargs grep "#define UINT"

now what if I wanted to output the results to a file?

I want to get the time when program starts and finishes. But it always show the same time. Here is my shell script. But it always show that `START TIME` is same as `END TIME`.
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_4" "L_3" "L_4")
subject="The job is finished"
START=$(date +"r")
address="/home/campus27/zwang10/Desktop/AWRR/program/power/vmodel_1/nprot/K_10"
ssh -f "${host_list[0]}" "cd '$address' && nohup Rscript '${program[0]}.R' > '${program[0]}_sh.txt';echo 'The job\n $address\n${program[0]} is finished\nSTART TIME = $START\n' END TIME =`date +"%r"` | mutt zwang10@mtu.edu -s '${host_list[0]} - Job ${program[0]}.R finished' -a '$address/${program[0]}_sh.txt';"

Hello everyone,

I recently started using "function" and "case" in linux but I came across a slight problem

My code:

Code:

function Return
{
echo $1
}

case "$1" in 
 ""       ) echo "give parameters please";;
 [0-9]*   ) echo "No numbers please";;
 *        ) Return;;

So whenever the first parameter is a simple word I would like it returned, but it seems like there is no returned string (empty space)

Also I know I can just write "echo $1" instead of Return, but I'd like to use a function for this.

Can anyone tell me why the function doesn't return $1? Thanks!
