when putting lb into an nginx var/www/{websitename} directory and running it, it returns an error

[henrykorteling]

the error returned:

lb: 13: read: Illegal option -e

the only thing I changed was the stuff in the file that was recommended to be changed.
also i got the script by git clone and mv into the final directory
how do I fix this?

[henrykorteling]

fixed it by running bash lb instead of sh lb
