Question How to auto pass password in shell script !
Hi all,

I have a simple script to check the CPU, Swap Memory and Hard Disk. But I can auto assign password in the script to automatic run it in crontab.

Quote:
#! /bin/bash

# Total memory space details

echo "Memory Space Details"
free -t -m | grep "Total" | awk '{ print "Total Memory space : "$2 " MB";}'
free -t -m | grep "Total" | awk '{ print "Memory Usage space : "$3 " MB";}'
total_mem=$(free -t -m | grep "Total" | awk '{ print $2 }')
mem_used=$(free -t -m | grep "Total" | awk '{ print $3 }')
percent1=$((($mem_used*100)/$total_mem))

echo "Memory Usage : $percent1%"


free -t -m | grep "Swap" | awk '{ print "Total Swap space : "$2 " MB";
print "Used Swap Space : "$3" MB";
print "Free Swap : "$4" MB";
}'
Everytime when I run this script, it require to insert password like the message below :

Quote:
test:~ # ssh root@192.168.1.1 'bash -s' < /home/scripts/memLinux.sh
root@192.168.1.1's password: xxxx
Memory Space Details
Total Memory space : 65207 MB
Memory Usage space : 31438 MB
Memory Usage : 48%
Total Swap space : 32773 MB
Used Swap Space : 2161 MB
Free Swap : 30611 MB
How can I solve this problem ?

rc

RC(8)							      System Manager's Manual							     RC(8)

NAME

       rc - command script for auto-reboot and daemons

SYNOPSIS

       /etc/rc
       /etc/rc.local

DESCRIPTION

       Rc is the command script which controls the automatic reboot and rc.local is the script holding commands which are pertinent only to a spe-
       cific site.

       When an automatic reboot is in progress, rc is invoked with the argument autoboot and runs a fsck with option -p to ``preen'' all the disks
       of  minor  inconsistencies  resulting from the last system shutdown and to check for serious inconsistencies caused by hardware or software
       failure.  If this auto-check and repair succeeds, then the second part of rc is run.

       The second part of rc, which is run after a auto-reboot succeeds and also if rc is  invoked  when  a  single  user  shell  terminates  (see
       init(8)), starts all the daemons on the system, preserves editor files and clears the scratch directory /tmp.  Rc.local is executed immedi-
       ately before any other commands after a successful fsck.  Normally, the first commands placed in the rc.local  file  define  the  machine's
       name,  using  hostname(1), and save any possible core image that might have been generated as a result of a system crash, savecore(8).  The
       latter command is included in the rc.local file because the directory in which core dumps are saved is usually site specific.

       init(8), reboot(8), savecore(8)
