Problem With Running Bash Script

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";

hello Experts!
need some help here with python FTP. so what i'm trying to do is, from a linux machine, ill be sending over a python script to a windows machine via python ftp. that works fine with no problem. now, i want to execute that python script i sent remotely. im having trouble with that. here's my code to just execute the script:

p.s : please dont suggest other options such as python paramiko due to many network security reasons

Code:

ftp = ftplib.FTP("windows machine name")
ftp.login("username", "password")
ftp.cwd("where\\python\\script\\is kept\\")

ftp.sendcmd("python myscript.py")

but looks like it doesn't recognize that command. how do i accomplish this please?

Hello,

I am setting up a linux server for gaming and I am using a script to update the files automatically and create a folder with a certain name.

Code:

# !/bin/bash

# A convenience function, to save us some work
update_server() {
	# Read the app id and the directory into a variable

	APP_ID=$1
	DIR=$2

	# Create the directory ( if it does not exist already )
	if [ ! -d "$HOME/$DIR" ]; then
		mkdir -p "$HOME/$DIR"
	fi

	# Uh-oh, it looks like we still have no directory. Report an error.
	if [ ! -d "$HOME/$DIR" ]; then
		# Describe what went wrong
		echo "ERROR! Cannot create directory $HOME/$DIR!"

		# Exit with status code 1 ( which indicates an error )
		exit 1
	fi

	# Call SteamCMD with the app ID we provided and tell it to install
	./bin/steamcmd.sh +login anonymous +force_install_dir "$HOME/$DIR" +app_update $APP_ID validate +quit
}

# Now the script actually runs update_server ( which we just declared above ) with the id of the application ( 4020 is Garry's Mod ) and the name of the directory we want the server to be hosted from:

update_server 4020 "gmodserver"

exit 0

When I run this script, it creates 2 folders on my server : gmodserver and gmodserver? There is no files downloaded in gmodserver. All the files are downloaded in gmodserver?

I looked for a few hours on how to solve this problem but I have no idea what the added ? might be so I am lost as to what to look for. Could you help me on figuring this out?

Thank you.

edit : I am using ubuntu 15.04 x64 if it makes a difference.

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

Hy All,

I have two nodes running RHEL 6.4 which are in cluster. I have clustered httpd service. Now I have certain application suppose X which reside in SAN partition. Now my job is to only automate this script to run by analyzing httpd status. I have successfully created the script apptrigger.sh whose content is given below,

-bash-4.1$ cat apptrigger.sh
a=0
b=0
c=0
d=0
a="service httpd status"
b=`eval $a`
##### CHECKING WHETHER HTTPD SERVICE IS RUNNING OR NOT #####
if [ "$b" != "httpd is stopped" ]; then
c="bash /switchapp/switch/ezlinkenterprise/bin/ezlink-cluster.sh status"
d=`eval $c`
##### CHECKING WHETHER EZ IS RUNNING OR NOT #####
if [ "$d" != "EzTaskMgr is Running" ]; then
ezstart
fi
fi

I have created this script in say test user. Now when I put this script to automate or run every minute through test user and defined its value in crontab -e of test user whose content is as shown below
$crontab -l
* * * * * /bin/bash /home/test/apptrigger.sh

but this script is running as root user so I cannot get the o/p
I think some environment variable need to be set. Anyone can guide me with this step? Thanks for your views and suggestion.

i need a bash script to switch to zero second on ac the waiting time for turning off the monitor (highlighten in red). same as for on battery (highlighten in purple)

Code:

<?xml version="1.0" encoding="UTF-8"?>

<channel name="xfce4-power-manager" version="1.0">
  <property name="xfce4-power-manager" type="empty">
    <property name="power-button-action" type="empty"/>
    <property name="show-tray-icon" type="empty"/>
    <property name="logind-handle-lid-switch" type="bool" value="true"/> 
    <property name="dpms-on-ac-sleep" type="uint" value="1"/>
    <property name="dpms-on-ac-off" type="uint" value="2"/> 
    <property name="brightness-on-battery" type="uint" value="9"/> 
    <property name="dpms-on-battery-sleep" type="uint" value="1"/>
    <property name="dpms-on-battery-off" type="uint" value="2"/> 
    <property name="lock-screen-suspend-hibernate" type="bool" value="false"/>
    <property name="dpms-enabled" type="bool" value="true"/>
  </property>
</channel>

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?

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';"

I am using linux mint and the grub menu gets configured automatically using scripts in /etc/grub.d. The menuentry that gets created is something like Code:

"linux mint (on /dev/sda1)"

. I use external drives sometimes and also have linux on my harddrive which I also switch between computers. It gets confusing when it says /dev/sda2 when it means something else. It boots fine because that actual boot command uses uuid. How can I change the text of the (script generated) description to also use partition labels or uuid (or the first few chars) just so I know which install will actually boot. like this: Code:

"Linux Mint (OFFICESSD)"
"Linux Mint (HOMEHDD)"
"Ubuntu (SANDISK)"
"Ubuntu (IMATION)"

I realise (maybe its the best way) I can change the "GRUB_TITLE=Linux Mint 17 Cinnamon 64-bit" in /etc/linuxmint/info but would rather a smoother way.

This is my script and the syntax to run this script is give ip and next will be the file or script you want to perform on remote server



#!/bin/bash

# The private key used to identify this machine
IDENTITY_KEY=/home/adnew.pem

syntax()
{
echo "Syntax: Ec2.sh server_ip scriptFile]"
echo "For example: ./Ec2.sh server_ip scriptFile"
exit 1
}

if [ $# -ne 2 ]
then
echo not enough arguments
syntax
fi


echo "Running script $2 on $1"
ssh -ttq -i $IDENTITY_KEY ec2-user@$1 sudo -i 'bash -s' < $2
exit
exit
echo "Done"



on script file i have give for testing

touch /root/test
ls /root/test
exit
exit

it makes the file but do not show the ls output by giving error


tcgetattr: Inappropriate ioctl for device

exit


what I have to do ??
