Can't execute global Node.js module from Bash shell script (Truffle)?

Question

I installed Truffle, the Ethereum development toolkit, on my Ubuntu 14.04 PC. I can execute it easily from a terminal window by simply typing "truffle". However, when I try to execute Truffle from a Bash shell script, I get the following error:

ide-do-truffle.sh: line 3: truffle: command not found

The line inside the shell script is just:

truffle compile --network local

How can I execute Truffle from within a shell script?

If someone can also explain what goes on behind the scenes when you execute a globally installed Node.JS package like Truffle, that would be helpful too.

Answer 1

Its possible the PATH in your terminal window is not the same as the PATH that your shell script sees.

Try echo "$PATH" in both your terminal window and in your script just before your truffle line in your script, and compare the two. If there is a difference, then the problem is with the PATH in your shell script.
