Storing Grep Files into Var and comparing it
Hi,

I was working on the password policy settings of Solaris where i wanted to grep the results of MINDIFF and comparing it to if else to make it into a auditing script.

I stored the grep into VAR1 and compare it if MINDIFF=3 but it doesnt work.
Can anyone help me with it?
Code:
!#/bin/bash

clear

echo "Checking Password Profile Policy"

VAR1= `grep "MINDIFF" "/etc/default/passwd"`
echo $VAR1

        if [ $VAR1  == "MINDIFF=3" ];
        then
        echo "MINDIFF is set to 3, which.."
        else
        echo "HELLO";
fi

There was a space between VAR1 and =
Code:
VAR1=`grep "MINDIFF" "/etc/default/passwd"`

If the entry is commented, then of course it will display "HELLO".

And use double quotes around "$VAR" in the "if" condition, cause it will throw a syntax error if the entry is not found in the file.
Code:
if [ "$VAR1"  == "MINDIFF=3" ];

Something similar...
Code:
test `grep -c ^MINDIFF=3 /etc/default/passwd` -eq 1  && echo "MINDIFF is 3" || echo "Oops"

HTH

... and correct the first line (the shebang line). Also lose the excess semi-colons. I've also given the code a more conventional indentation.

Code:
#!/bin/bash

clear

echo "Checking Password Profile Policy"

VAR1=`grep "MINDIFF" "/etc/default/passwd"`
echo "$VAR1"
if [ "$VAR1"  == "MINDIFF=3" ]
then
         echo "MINDIFF is set to 3, which.."
else
         echo "HELLO"
fi
