Thank you. This works in the terminal perfectly. However, it doesn't seem to work in a bash script. Been messing around with all sorts of way for hours now.

An example :

Code:
#!/bin/bash
# Script to add a startup item

username=somethingrandom

cp /etc/init.d/originalfile /etc/init.d/$username
sed 's!changeusername!$username!' /etc/init.d/$username > tempfile
mv tempfile /etc/init.d/$username
chown root:root /etc/init.d/$username
chmod 777 /etc/init.d/$username

I've renamed the file in the script to changeusername so its easier. However it doesn't work with the string $username present. If i were to replace $username with "somethingrandomhere" then it would work. However, i want it to change according to the username that i've given in the script.

(Script has been modified for the thread so it would be less complicated. In the real script, I would be asked to input the username)

paste

PASTE(1)						      General Commands Manual							  PASTE(1)

NAME

       paste - paste multiple files together

SYNOPSIS

       paste [-s] [-d list] file...

OPTIONS

       -d     Set delimiter used to separate columns to list.

       -s     Print files sequentially, file k on line k.

EXAMPLES

       paste file1 file2   # Print file1 in col 1, file2 in col 2

       paste -s f1 f2	   # Print f1 on line 1 and f2 on line 2

       paste -d : file1 file2
			   # Print the lines separated by a colon

DESCRIPTION

       Paste  concatenates  corresponding  lines of the given input files and writes them to standard output. The lines of the different files are
       separated by the delimiters given with the option -s. If no list is given, a tab is substituted for every linefeed, except  the	last  one.
       If  end-of-file	is hit on an input file, subsequent lines are empty.  Suppose a set of k files each has one word per line.  Then the paste
       output will have k columns, with the contents of file j in column j.  If the -s flag is given, then the first file is on line 1, the second
       file on line 2, etc.  In effect, -s turns the output sideways.

       If  a list of delimiters is given, they are used in turn.  The C escape sequences 
, 	, \, and  are used for linefeed, tab, backslash,
       and the null string, respectively.
