What Is A Good Linux Script For Changing An IP Address Statically In Ubuntu?

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 a shell script named by test.sh, for example containing
Code:

address="$PWD"
echo "$address"

.
If I put it in folder temp1, and run test.sh, then it will give me the address of the current directory. But if I am now in folder temp2, and I want to run test.sh, I always need to copy test.sh to folder temp2, and then run it. Is there a way that I can run test.sh without copying it? I am not root user.

i have been trying to get this peice of code to work but i cant seem to get it to work.
im just starting out coding and kinda poking around in the dark to get this resolved, any help would be much appriciated, thankyou

Hi All,

Im trying to create a script which checks the creation time of a file and if it is more than ten minutes, send out an alert.

For ex : Creation date of file is 10:30 AM
current time is 10:45 AM

Then send an alert/ message.

This is the script i wrote below :

Code:

#!/bin/ksh

filename="/apps/log/file.txt"

if [ -f "${filename}" ]
then
        createTime=`ls -lad "${filename}" | awk '{print $8}'`
        echo "$createTime"
        currentTime=`date '+%M'`
        echo "$currentTime"
        DIFF=$(( $currentTime - $createTime )) 
        echo "$DIFF"

else

        exit 1

fi

I am getting syntax error on the subraction when i try to run this script . I can understand that creation time and current time is in different format thats y this error throws, but i dont know how to rectify it .

I need to find out if the file creation time is more than ten minutes.

Please help me in achieving this output.

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

I have a similar script as follows

Code:

(sleep 5m; echo "set_property volume 85 > "fifo_file")&

mplayer -volume 95 -quiet -slave -input file="fifo_file" song1 song2 song3

This makes the current song change volume to 85 after the 5 minute sleep period, but any songs after that revert to 95.

I want to keep it at volume 85 until the mplayer command completes but start at 95 until changed.

Is this possible?

I'm trying to send all root's mails to an external e-mailaddress, but for some reason I can't get it to work.

I've edited /etc/aliases with the following rule:

root: <myexternal@email.address>

and run newaliasses after, which would run without any errors.

I can run: echo "Testing" | mail -s "Server Testing" <myexternal@email.address>
just fine without any issue and it's being delivered correctly to my external address.

But when I run: echo "Testing" | mail -s "Server Testing" root

I (first) get a "Deferred: 451 Temporary local problem - please try again later" error and when I then run: "Sendmail -OTimeout.hoststatus=0m -q -v" to flush the mailqueue it says everything is ok, but I then get a message saying I have new mail in /var/spool/mail/root and I don't get the mail on my external e-mailaddress.

I have no clue where to look next, hopefully you guys can point me in the right direction.

Just for completeness: I use mageia release 4 (x86_x64).

The two charge controllers for my solar system are connected to my router allowing my computer to access them for data gathering. Using the address required in Windows is "tsmppt13190256/" for one of them ( tsmppt plus the serial number ). This address works with all browsers with windows .

Using the same browser on various Linux machines yields "web page not found" Morningstar ,who makes these excellent controllers , says they support only Windows. I've tried using the numbered ( 4 groups of 4 digits ) equal and even the "tiny URL" but nothing works .

I've tried adding ".,com " and HTTP:// "

How can I how can I get my Linux browsers to accept this address ?

Thanks a lot .
