[bash]Stripping lines from a list
Hello!

I have a script that is (among other things) doing the following:
Code:
list=/tmp/list1.txt
ncftpls -u <user> -p <password> -x "-l1" server.domain.tld > $list
cat $list | nl
echo "Choose file: "
read file
cat /tmp/list1.txt | nl | grep $file | sed -e "s/$file//g" -e "s/ //g" | column -t > /tmp/list2.txt
cat /tmp/list2.txt

With this, i want to choose a file that is located on a server and download it.
the sed lines was given to me on a guy on another forum who said it should do the trick. And it did, somewhat.
In the directory, i have around 40 files.
if i choose 1 - 9, it gives me a list with several lines like this

Code:
Choose file:
9
2 full_mysql_dump_2008-03-24_0:00.sql.gz full_mysql_dump_2008-03-25_06:00.sql.gz 10 full_mysql_dump_2008-03-25_0:00.sql.gz 18 full_mysql_dump_2008-03-26_0:00.sql.gz 1 full_mysql_dump_2008-03-26_12:00.sql.gz 2 full_mysql_dump_2008-03-28_06:00.sql.gz 30 full_mysql_dump_2008-03-28_0:00.sql.gz 35 full_mysql_dump_2008-03-2_00:00.sql.gz 3

but if i choose a higher number, it gives me this:
Code:
Choose file:
33
full_mysql_dump_2008-03-28_18:00.sql.gz

Just as i want it to do.

In this other script that i am working on, i am using the exact same thing, but this time with another directory on the same remote server, where it is only 2 files. (there will be more files there later).
The result is like the first example.
It doesn't cut away all the other lines that i don't want to have there.

Any of you guys who may know what is wrong, or maybe another solution for my problem?

libbash

LIBBASH(7)							  libbash Manual							LIBBASH(7)

NAME

     libbash -- A bash shared libraries package.

DESCRIPTION

     libbash  is  a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash scripts whose functions you may
     want to load and use in scripts of your own.

     It contains a 'dynamic loader' for the shared libraries ( ldbash(1)), a configuration tool (ldbashconfig(8)), and some libraries.

     Using ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1).  A bash shared library that can be  loaded
     using
     ldbash(1) must answer 4 requirments:

     1.     It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash).

     2.     It must contain a line that begins with '#EXPORT='.  That line will contain (after the '=') a list of functions that the library
	    exports.  I.e. all the function that will be usable after loading that library will be listed in that line.

     3.     It must contain a line that begins with '#REQUIRE='.  That line will contain (after the '=') a list of bash libraries that are
	    required for our library.  I.e. every bash library that is in use in our bash library must be listed there.

     4.     The library must be listed (For more information, see ldbashconfig(8)).

   Basic guidelines for writing library of your own:
     1.     Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define) only functions.

     2.     Try to declare all variables intended for internal use as local.

     3.     Global variables and functions that are intended for internal use (i.e are not defined in '#EXPORT=') should begin with:
		  __<library_name>_
	    For example, internal function myfoosort of hashstash library should be named as
		  __hashstash_myfoosort
	    This helps to avoid conflicts in global name space when using libraries that come from different vendors.

     4.     See html manual for full version of this guide.
