No offense, but I'm sorry, that's a really hideous script. I guess the problem is that you are grepping without anchoring the grep, so it prints any line which contains the indicated number anywhere.
Here is a refactored version, with the following changes.
* cat file | command is known as "Useless Use of Cat". Changed those.
* grep | sed similarly refactored to use only sed, anchored at the beginning
* You use $file and /tmp/file1.txt interchangeably. Standardize on the former.
* Since you are not using file1 without the nl, doing the nl once and saving it in the file.
* Remove the temp file when done.
* The second temp file is apparently unnecessary, unless you are only showing part of the script.
Code:
list=/tmp/list1.txt
trap 'rm $list' 0 # remove temp file at exit
trap 'exit 127' 1 2 3 5 15 # remove temp file if interrupted
ncftpls -u <user> -p <password> -x "-l1" server.domain.tld | nl > $list
echo "Choose file: "
# maybe display the list to the user:
# pr -bt2 "$list"
read file
sed "s/^ *$file //g" | column -t

I want to create a temp file which is named based on a search string. The search string may contain spaces or characters that aren't supposed to be used in filenames so I want to strip those out.
My thought was to use 'tr' with but the result is the opposite of what I want:

Hello,
I was wondering if there was an easy way to take lines from a single-column list, and remove them from a second single-column list. For example, I want to remove the contents of list 1 from list 2. How would I do this?

In this post I came across the cited construct. It works! while ... { list; } does not.
man bash does not mention it (or, better, I didn't see it).
Any reason for / behind this? Am I missing something? (5 Replies)

fmt
fmt(1) General Commands Manual fmt(1)NAME
fmt - format text
SYNOPSIS
width] [file...]
DESCRIPTION
The command is a simple text formatter that fills and joins lines to produce output lines of (up to) the number of characters specified in
the width option. The default width is 72. concatenates the arguments. If none are given, formats text from the standard input.
Blank lines are preserved in the output, as is the spacing between words. does not fill lines beginning with a period for compatibility
with Nor does it fill lines starting with
Indentation is preserved in the output and input lines with differing indentation are not joined (unless is used).
can also be used as an in-line text filter for the command:
reformats the text between the cursor location and the end of the paragraph.
Options
recognizes the following options:
Crown margin mode.
Preserve the indentation of the first two lines within a paragraph and align the left margin of each subsequent line with that
of the second line. This is useful for tagged paragraphs.
Split lines only.
Do not join short lines to form longer ones. This prevents sample lines of code, and other such "formatted" text, from being
unduly combined.
Fill output lines to up to
width columns.
WARNINGS
The width option is acceptable for BSD compatibility, but it may go away in future releases.
