All,

My environment is Red Hat Enterprise Linux 5.

I am using the following condition --

if [[ $z -gt 5 -a $z -lt 7 ] -0 [ $y == 'VALID' ]]

Please help me

You're getting your ]'s and ]]'s mixed up, if you start with [[ always end with ]], they're not nesting brackets.

Hi

I tried with following combinations,

if [[ $z -gt 5 -a $z -lt 7 ] -o [ $y == 'VALID' ]]

if [ $z -gt 5 -a $z -lt 7 -o $y == 'VALID' ]

if [ $z -gt 5 ]-a [ $z -lt 7 ] -0 [ $y == 'VALID' ]

nothing is working fine.

Can you please provide the correct one

How about ...

Code:
if ([ $z -gt 5 ] && [ $z -lt 7 ]) || [ $y == 'VALID' ]

Try this. The condition is the same each time, we just change the data for each test.

Code:
z=6
y="VALID"
if [ \( ${z} -gt 5 -a ${z} -lt 7 \) -o \( "${y}" = "VALID" \) ]
then
      echo "TRUE: ${z} ${y}"
else
      echo "FALSE: ${z} ${y}"
fi


z=5
y="VALID"
if [ \( ${z} -gt 5 -a ${z} -lt 7 \) -o \( "${y}" = "VALID" \) ]
then
      echo "TRUE: ${z} ${y}"
else
      echo "FALSE: ${z} ${y}"
fi

z=6
y="ORANGE"
if [ \( ${z} -gt 5 -a ${z} -lt 7 \) -o \( "${y}" = "VALID" \) ]
then
      echo "TRUE: ${z} ${y}"
else
      echo "FALSE: ${z} ${y}"
fi

z=4
y="ORANGE"
if [ \( ${z} -gt 5 -a ${z} -lt 7 \) -o \( "${y}" = "VALID" \) ]
then
      echo "TRUE: ${z} ${y}"
else
      echo "FALSE: ${z} ${y}"
fi



./scriptname 
TRUE: 6 VALID
TRUE: 5 VALID
TRUE: 6 ORANGE
FALSE: 4 ORANGE

#! /bin/bash

if ([ $1 -gt 5 ] && [ $1 -lt 7 ]) || [ $2 == 'VALID' ]
then
  echo "true"
else
  echo "false"
fi

exit 0

Code:
[house@leonov] sh test.bash 5 VALID
true
[house@leonov] sh test.bash 6 VALID
