BASH script question / create a script that gets a filename as an argument
Hi,

I want to create a script that gets a filename as an argument.
The script should generate a listing in long list format of the current directory, sorted by file size.
This list must be written to a new file by the filename given on the command line.

Can someone help me with this?

Here is my start:

Code:
#!/bin/sh
echo "Please give in the filename"
read NEW_FILENAME
#read the current directory in long listing and sort by filesize (small to big) and writes it to the given filename
ls -l -S -r  > $NEW_FILENAME

But I am kind of stuck.

Thanks for your help so far.

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.

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.
