I was thinking that perhaps my version does not support substr in expr expressions, how can i check this?

You can test your expr command with :

Code:

expr substr abcdef 2 3    # Gives bcd
expr substr @DATABASE 2 3 # Gives DAT
expr substr @DATABASE 2 999 # Gives DATABASE

The expr command can be replaced by cut :

Code:

entry=`echo "$record" | cut -c2-`

Thanks aigles, the cut option worked.

When i done the expr option, it gave the same error at the terminal window, however what I find weird is that the substr option appears in the man pages.

aww well, thanks again.

Hi

I am still working on this problem, well actually just getting back round to it, anyway I have implemented the arrays as suggested above but instead of having the output as above, i.e. with line: eval echo \"${array}[${i}]=\${${array}[${i}]}\"

I just want to place each value within the array into a variable.

Currently my code is:

for arrays in packageSpecs packageBodies procedures triggers functions views sqlScripts
do
eval count=\${#${arrays}[*]}

if [ $count -eq 0 ]
then
echo "${arrays}: Nothing to be verified"
else
counter=0

while [ $counter -lt $count ]
do
eval echo \"\${${arrays}[${counter}]}\"

fileToVerify=eval \${${arrays}[${counter}]}\

echo "Verifing: $fileToVerify"

counter=$counter+1
done
fi

But this does not work as expected, I know its the line: fileToVerify=eval \${${arrays}[${counter}]}\ that gives me issues and have tried different ways to write this line looking at what agiles done above, can someone please tell me what I am doing wrong? Thanks

Try to change :

Code:

fileToVerify=eval \${${arrays}[${counter}]}\

by

Code:

eval fileToVerify=\${${arrays}[${counter}]}

Please use [CODE] tag...


Jean-Pierre.

Thanks (again), worked a treat.

Sorry never seen the [code] tags, will use next time
