I'm using ubuntu 14.10

I'm unable to find common commands in my script files which worked perfectly since a few days back.I have to give complete path for them now.

```
           /bin/mkdir "beta1"
           /usr/bin/npm install "$COMMAND"

```

which should be like :

```
           mkdir "beta1"
           npm install "$COMMAND"

```

I've even tried adding source ~/.profile in my script but nothing helps.
