Reading an Input file and searching for occurrences WIHOUT SED or AWK
Hi people. I am new to shell scripting, so I need a little help. I want to create a script named that takes an argument as a file, Read the input file and look for occurrences of the current username (say abc.xyz) who is executing the script. On finding an occurrence of the username take that line and append it to a file and display a line number and a bracket against the saved line. WITHOUT USING SED OR AWK

for eg: the newly created file should look similar to this:
1) PWD=/home/abc.xyz
2) USER=abc.xyz
3) ... abc.xyz
4)..

i have created a script that is doing just about the same thing.

echo "Precisely Enter the file path";
read filename;

varible=$(whoami);

grep -n $varible $filename >> Userfile;

more Userfile;



but the output of the file is coming as (obviously coz of -n)
9:jhhf=/kjsd/abc.xyz
14:var/spool/mail/abc.xyz
15:/home/abc.xyz
21:/home/abc.xyz
23:abc.xyz

I BASICALLY WANT TO REORDER THE OUTPUT IN A SEQUENCE AS

1)
2)
3)
4)

any help would really appreciated!

is there a command that does that.

readproctitle

readproctitle(8)					      System Manager's Manual						  readproctitle(8)

NAME

       readproctitle - maintains an automatically rotated log in memory for inspection by ps(1).

       readproctitle is available in daemontools 0.75 and above.

SYNOPSIS

       readproctitle L D

DESCRIPTION

       L consists of any number of arguments.  D is one argument consisting of at least five dots.

       readproctitle  reads  data  into  the  end  of  D,  shifting D to the left to make room. This means that the most recent data is visible to
       process-listing tools such as ps(1).  readproctitle always leaves three dots at the left of D.

       For example, if

	readproctitle io errors: ....................

       reads the data

	fatal error xyz
	warning abc

       then its command-line arguments change to

	readproctitle io errors: ... xyz!warning abc!

       with a newline character in place of each !. Process-listing tools typically show the newline character as ? or 
.

       readproctitle exits when it reaches the end of input.

       Beware that most implementations of ps(1) have small argument-length limits. These limits apply to the total length of readproctitle  L	D.
       I have not seen a system with a limit below 512 bytes.
