shell script

sudo -u postgres -H sh -c "cd /usr/local/src/postgresql-8.2.10;export PERL5LIB=/usr/lib/perl5;export CC="gcc -m32";export LD="ld -melf_i386";export CFLAGS="-m32";export LDFLAGS="-m32";setarch i386"

I am trying to write script to execute the above lines.  How can I script it?  

1. I need to login as postgres account
2. need to set the following variables

export PERL5LIB=/usr/lib/perl5  
export CC="gcc -m32"
export LD="ld -melf_i386"
export CFLAGS="-m32"
export LDFLAGS="-m32"
setarch i386

3.  need to run the following command
./configure --prefix=/pgarc/pgsql --with-perl

4. gmake

Put the commands in a file (vg. MyScrtpt.sh)1

#!/bin/ksh
#
# Script: MyScrtpt.sh
#
# 1. I need to login as postgres account

cd /usr/local/src/postgresql-8.2.10

sudo  su -  postgres    #<= Here goes the postgres account ...

# 2. need to set the following variables

export PERL5LIB=/usr/lib/perl5  
export CC="gcc -m32"
export LD="ld -melf_i386"
export CFLAGS="-m32"
export LDFLAGS="-m32"
setarch i386

# 3.  need to run the following command

./configure --prefix=/pgarc/pgsql --with-perl

# 4. gmake 

gmake          #<= What goes here ????

exit

Open in new window

Then make it executable:
chmod +x MyScrtpt.sh

[root@rhel5 scripts]# ./myscript.sh
[postgres@rhel5 ~]$

when I run this script its su - postgres and waits there.

[postgres@rhel5 ~]$ exit
logout
-sh-3.2#

-sh-3.2#exit

then it is started to run the ./configure part...

why this happens.

my concern is it should run as soon as su - postgres.

The sudo should be outside the script and the script run by the sudo command.

ie comment out the sudo line in your script and then run the script using

sudo -u postgres myscript.sh

try this instead of your su line

if test `whoami` != postgres
then sudo su postgres -c "/bin/sh $0"
  exit $?


or alternatively

cat <<EOF |sudo su postgres -c "/bin/sh"
....
EOF
