Command Not Found In shell/bash scripts

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.

Use of PATH as a variable name was the issue. I was overriding it at some point.

If the path you posted in the comments is a verbatim copy/paste of your path, your problem is you have embedded NON-ASCII characters in your path. This is most likely due to having edited your path using an editor in windows (or a non-text editor e.g. OpenOffice) that has substituted a non-standard character for a regular ASCII value. Looking at a hexdump of your PATH shows the problem:

$ hexdump -C -n 233 pathprob.sh

Notice how usr/loc......al/games appears. There is a similar problem with java-7-oracle....... This effectively corrupts your PATH variable. The corrupting characters are the same in both places e2 80 8c e2 80 8b. They represent a e2 80 8c a Unicode ⁌ and e2 80 8b a Unicode ⁋.

The soluton -- copy your path to a text editor. Delete/replace local/ with a new retyped local/ and do the same thing for /usr/lib/jvm/java-7-oracle/db/bin
