I'm having problems with recognizing command line args in my script, whatever "if" I make, they all evaluate to true, what am I doing wrong? here's my test script:

(Toggle Plain Text)

#!/usr/bin/bash

if [ $1=blah ]; then
    echo no quotes
fi

if [ $1="blah" ]; then
    echo quotes
fi

if [ $1="foo" ]; then
    echo foo
fi

echo $1

And here's my output:

(Toggle Plain Text)

bash-2.05$ ./test.sh blah
no quotes
quotes
foo
blah
bash-2.05$

Thank you very much in advance
