bash help [solved]

Hi,

I'm writing a bash script and I am trying to test 2 strings in the same if statement, and it doesnt read the second statement,

if [ "$1" != "dbstart" -o "$1" != "dbstop" ]
then
  echo 'use dbstart or dbstop'
else
  su - postgres -c "sh ${1}.sh"
fi

I have also tried || with no success.  The only way to make this work is to use a separate elif statement for each string.

So, is the "or" impossible or did I miss something really stupid?? thanks

Re: bash help [solved]

I think you want "and", not "or".

if [ "$1" != "dbstart" -a "$1" != "dbstop" ]

I would not use [ ] tests though. If you are writing bash, use [[ ]] instead!
