If you tried, I don't think you could be more vague.

Based on such limited information the best I could suggest is that you didn't export one or more variables from wherever you are trying to run filename.sh from (sh filename.sh - not an issue when you source (with .) filename.sh).

Please try to be more descriptive than saying "It does not work".

Running it "sh ..." will run the script in a new sub-shell (sh - or whatever that point to (bash, ksh, dash, etc.)). Running it with . will source (effectively load) it into the current shell's environment.

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
