Upgraded to 13.04, command not found errors

Question

I'm getting command not found errors on all my scripts I try to run since upgrading. For instance if I navigate to a directory in terminal and then try to execute a script I receive this error. The scripts do have executable permissions.

I did mess around with my path at one point, I don't know if I've messed it up somehow?

    # if running bash
if [ -n "$BASH_VERSION" ]; then
    # include .bashrc if it exists
    if [ -f "$HOME/.bashrc" ]; then
    . "$HOME/.bashrc"
    fi
fi

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin"
fi

Update If I run the scripts with "bash" in current dir in the terminal the scripts run i.e. bash myscript, however without it I still get command not found error. Would this imply bash is no longer in my path? If so how do I fix this?

Results of echo $PATH

/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

Pretty sure I have spotted a mistake.

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin"
fi

Does not include the users private bin in the path. Your path is just $HOME/bin

Try this instead

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

You can confirm if this is the problem with echo $PATH but as the path you have posted looks OK this tells me that you dont have a $HOME/bin directory.
