sed - How to confirm substitution
How to confirm whether a particular substitution taken place or not ?

Find the code below :-

Code:
#!/bin/ksh
COUNT=0
#######  Create backup of the original file  ######
cp passwd passwd_old
#######  Read the csv file for unixid and project ######
while IFS=, read unix_id project_id
do
  UNIX_ID=${unix_id}
  PROJECT_ID=${project_id}
############ replace UNIX_ID with PROJECT_ID ##############
  print "converting $UNIX_ID to $X_ID .........................." >>log
  sed "s/$UNIX_ID/$PROJECT_ID/g" passwd >> passwd-new
  cp passwd-new passwd
  rm passwd-new
done < ids.csv

Now what I need is to detect whether a particular unix_id exists or better to confirm whether a particular substitution from unix_di to project_id taken place or not so that error logs and other logs can be generated efficiently

NAME

       times - shell built-in function to report time usages of the current shell

SYNOPSIS

   sh
       times

   ksh
       times

DESCRIPTION

   sh
       Print the accumulated user and system times for processes run from the shell.

   ksh
       Print the accumulated user and system times for the shell and for processes run from the shell.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

       1.  Variable assignment lists preceding the command remain in effect when the command completes.

       2.  I/O redirections are processed after variable assignments.

       3.  Errors cause a script that contains them to abort.

       4.  Words,  following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
	   able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation  are  not
	   performed.
