How to get Bash File to Run all Commands in File?

Experts,

I have the following file in .sh format. In RHEL5 I cannot get past the first step. The script stops on step 2. Not sure why?

#Logging:

LOG_FILE='/data/CDS_DATA/PS_DBInstall.log'2>&1 >> $LOG_FILE 

#
#
#Steps:
#
#Step 1. Create a profile backup. Replace current profile file with updated file. 2>&1 >> $LOG_FILE 

echo "Backup and copy the environment profile" 2>&1 >> $LOG_FILE 
/bin/cp /etc/profile /etc/profile.bak 2>&1 >> $LOG_FILE 
/bin/cp -f /home/tcdl/Desktop/profile /etc/profile 2>&1 >> $LOG_FILE 
#
#
#Step 2. su to root 2>&1 >> $LOG_FILE *****failing here
sudo su -               
#
#
#Step 3. Create a directory 2>&1 >> $LOG_FILE 
echo "Make /data/CDS_DATA directory" 2>&1 >> $LOG_FILE 
mkdir /data/CDS_DATA 2>&1 >> $LOG_FILE 
#
#
#Step 4. Set permissions 2>&1 >> $LOG_FILE 
echo "Set /data/CDS_DATA permissions" 2>&1 >> $LOG_FILE 
chmod -R 0700 /data/CDS_DATA 2>&1 >> $LOG_FILE 
chown -R cdsdb.cdsdb /data/CDS_DATA 2>&1 >> $LOG_FILE 
#
#
#Step 5. su to cdsdb 2>&1 >> $LOG_FILE   
su - cdsdb 2>&1 >> $LOG_FILE 
#
#
#Step 6. Move data file 2>&1 >> $LOG_FILE 
echo "Move /opt/co/CDSDB_ROOT/DATA to /data/CDS_DATA" 2>&1 >> $LOG_FILE 
/bin/mv /opt/co/CDSDB_ROOT/DATA/* /data/CDS_DATA 2>&1 >> $LOG_FILE 
#
#
#Step 7. Remove /opt/co/CDSDB_ROOT/DATA file 2>&1 >> $LOG_FILE 
/bin/rm -rf /opt/co/CDSDB_ROOT/DATA 2>&1 >> $LOG_FILE 
#
#
#Step 8. Create symlink to new data location 2>&1 >> $LOG_FILE 
ln -s /data/CDS_DATA /opt/co/CDSDB_ROOT/DATA 2>&1 >> $LOG_FILE  
#
#
#Step 9.su to root 2>&1 >> $LOG_FILE 
sudo su 2>&1 >> $LOG_FILE

read -p "Everything OK? If yes, press any key to reboot system, otherwise press ctl-c to break" 2>&1 >> $LOG_FILE 
/sbin/reboot 2>&1 >> $LOG_FILE

You need as the first line in the script:

#!/bin/bash

mccracky

didn't read that correctly.

You can't use sudo su - in a script.

You can't just run the script itself as root?

sudo script.sh

it's there I just took the main part of the script out because it had company info on it. Everything is there that is needed.
I had the steps 5-10 on one line. But my co workers thought it would be easier to read broken out.

I'm not sure what you mean...here is how I'm running the script
on konsole, su <enter> then enter the password for su. Then run the script /home/usr/desktop/DataMove.sh <enter>

mccracky

If you are already running the script as the root user, then why do you have step two (and nine) in there?

farzanj

You have to run this script as an ordinary user

Or, you have to comment out the lines that says sudo su -

Or, you have to add root user to sudo as well so that it can re-login to itself using sudo

Your 2>&1 > redirection is perfectly good, as long as there is a space before 2>

2>&1 >file

Open in new window

does not have the same affect as

>file 2>&1

Open in new window

For easier logging, change

LOG_FILE='/data/CDS_DATA/PS_DBInstall.log'2>&1 >> $LOG_FILE

Open in new window

LOG_FILE=/data/CDS_DATA/PS_DBInstall.log
exec >>$LOG_FILE 2>&1

Open in new window

Then you can get rid of all the redirection in the rest of the script, eg:

echo "Backup and copy the environment profile" 2>&1 >> $LOG_FILE

Open in new window

simply becomes

echo "Backup and copy the environment profile"

When you execute "sudo su ~", you create a new shell. It doesn't change the permissions on the current shell. The shell command which you invoked will wait until you exit from the new shell before continuing on to execute the next commands.

If you want to execute a command as root, run it as "sudo <cmd>".
