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

Hi,

i have a small problem on my system... I recently wrote a small bash script and added it via crontab -u root -e and it's executed as it should.
Then a few days after i did edit my bash script, but once it is run by cron it doesn't reflect the changes i made to the script. I did manually restart crond, tryed sync, moved my script, renamed it even rstart the server - no success.
If i run my script manually it returns me the expected output.
part of my script (/root/sd.sh):
Code:

#!/bin/sh

echo -n "Checking Raid... "
RAID=`tw-cli /c0/u0 show status | cut -c17-31 | grep -ci OK`
RAIDSTATUS=`tw-cli /c0/u0 show status | head -n1 | cut -c17-31`
if [ $RAID -eq 0 ]; then
  VERIFYING=`tw-cli /c0/u0 show status | cut -c17-31 | grep -ci VERIFYING`
  REBUILDING=`tw-cli /c0/u0 show status | cut -c17-31 | grep -ci REBUILDING`
  if [ $VERIFYING -eq 1 ]; then
    CURRENTSTATUS=`tw-cli /c0/u0 show verifystatus | head -n1 | cut -c46-49`
  fi
  if [ $REBUILDING -eq 1 ]; then
    CURRENTSTATUS=`tw-cli /c0/u0 show rebuildstatus | head -n1 | cut -c47-50`
  fi
  echo "Raid is busy (Raid $RAIDSTATUS$CURRENTSTATUS)"
  exit 1
fi
echo "Raid is idle (Raid $RAIDSTATUS)"

echo -n "Checking for logged in Users... "
USERS=`who | wc -l`
if [ $USERS -gt 0 ]; then
  echo "Users online"
  exit 1
fi
echo "None logged in"

crontab -l :
Code:

# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)

Any ideas why? - any help or thoughts appreciated

Hi All,

I have perl script which I am trying to run on 1st Monday via cron job.
So I scheduled it as follows:

0 0 1-7 * * root ["$(date '+%a')" = "Mon"] && /usr/bin/perl script.pl

But then it didn't run so checked cron log and it seemed like its missing the command. so added a \ in front of %a and then it picked up the whole command as per cron log.

But still it didnt ran the script. I then change the script to just && echo "test">/tmp/test

Still nothing. if I run it as /usr/bin/perl script.pl it runs though

Thanks in advance.

So I created this big script and want to ask for username and set a variable, however if the username exist in the username variable then continue with script otherwise ask the user to enter his name.

Flow:
-- start script "Enter User Name"
-- ask user to input username
-- if username is blank or different value then put that username in $USERNAME variable
-- then continue with the rest of the script

-- next time this user runs the script it will have his name loaded so he just presses enter to continue with the script.

-- If it is NOT the same user then, new user can erase existing input and enter a new name.

Hope it makes sense...

Thanks in advance for the help.

Hi

I have just started to use Linux on my Raspberry Pi to host a home automation server & I'm having a problem when trying to run a bash script.

The script in question is to turn off my Viera TV & is as follows
Code:

#!/bin/sh
curl -i \
-H "Accept: text/xml" \
-H "Cache-Control: no-cache" \
-H "Pragma: no-cache" \
-H 'SOAPACTION: "urn:panasonic-com:service:p00NetworkControl:1#X_SendKey"' \
-H "Content-Length: 200" \
-H 'Content-Type: text/xml;charset="utf-8"' \
-X POST --data '<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> \
<s:Body> \
<u:X_SendKey xmlns:u="urn:panasonic-com:service:p00NetworkControl:1"> \
<X_KeyEvent>NRC_POWER-ONOFF</X_KeyEvent> \
</u:X_SendKey> \
</s:Body> \
</s:Envelope>' http://192.168.1.87:55000/nrc/control_0/

If I run this from the command line it works fine but when I try to run it from within the Home Automation application it returns error code 32512 which I've seen elsewhere is actually exit status 127 & basically down to not being able to find the program to execute.

Permissions are fine & I've tried using the full path name for both curl and the script itself but I still get the error. Has anyone any idea what I need to change as this looks to be a pure Linux (or rather my misunderstanding of Linux) issue rather than the home automation program

Thanks

Steve

user="john bob randy susan"
I extracted local user list as: cat /etc/passwd | cut -d ":" -f1

Now I need to write a script to find the difference in user between these two (users defined as above and local user). I tried many ways its not working. Any help

#!/bin/bash
users="john bob randy susan"
luser=`/bin/cat /etc/passwd | cut -d ":" -f1`
......

Thank you

I created 3 test machine and made them into cluster.

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.

Hi All,

I have two scripts, the aim of these two scripts is, to check whether a particular script is running or not, if it wont runs, then throw a mail.

How i Achieved this output is, I wrote first script.

I created an infinite while loop which performs below steps

1. It creates a touch file
2. Triggers the script which needs to be monitored if its working or not.
3. Removes the touch file.

If the second step fails, then the remove file command will not happen and the script will stuck there itself.

I created an another script which checks the creation time of the touch file and if it is more than ten minutes, it means the second step in the first script is hanged, which also means that particular script is not working.

So if the creation time is more than 2 minutes the second script will throw a mail.

Below are the two scripts.

Code:

#!/bin/ksh



userid="chansd"

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

while true ;do
touch $filename
pass=`/apps/eDMZ/call_st.ksh $userid`
sleep 20
rm $filename
done

Below script checks the file creation time and throws email if it is older than 2 minutes
Code:

#!/bin/ksh


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

if [ -f "${filename}" ]
then
if test "`find $filename -mmin +2`"
then
echo "script is not working ! Please act on it" | mail -s "Script  is not working" Example@mail.com
fi


else

        exit 1

fi

What im going to do is

1. I am going to run the first script in background so it runs forever.
2. I am going to run the second script in cron forevry 5 mins to check the file creation time.

3. So if the first script hangs . I will kill the process using process id and after the issue resolves with the inner script, I will run the main script again.

I am new to Linux, Please let me know if this approach will work as expected.
