I have a very wierd case... If I run a script with /bin/bash, it can't recognize aliases that I set even inside the script. And the most strange thing

$ cat -n test.sh
    1 #!/bin/bash
    2 alias somecommand='ls -alF'
    3 alias
    4 somecommand
$ ./test.sh
alias somecommand='ls -alF'
./test.sh: line 4: somecommand: command not found

... as shown above, if I run the command "alias" in the script it turns out that bash has take my command "somecommand" into the aliases, but if I run the command "somecommand" itself it will still not be recognized!

Everything is right if I use the command "sh" to run the script.. so is it a bug of bash? Or is there something I'm missing?

Any help is appreciated!
