Thanks Balajesuri. It was very kind of you.

I had to tweak your code a bit to make it work.

I was getting invalid option "i" if I used sed -i. So this is what worked for me-

while read a b
do
sed "s|$a|$b|g" /tmp/ccf_temp.sql > /tmp/tmp.sql && mv /tmp/tmp.sql /tmp/ccf_temp.sql
done < /tmp/tt

rpl

RPL(1)							    BSD General Commands Manual 						    RPL(1)

NAME

     rpl -- replace strings in files

SYNOPSIS

     rpl [-LhiwbqvsRepfdt] [-xSUFFIX] <old_string> <new_string> <target_file ...>

DESCRIPTION

     Basic usage is to specify two strings and one or more filenames or directories on the command line.  The first string is the string to
     replace, and the second string is the replacement string.

     -h, --help
	     A short help text.

     -L, --license
	     Show the license and exit.

     -xSUFFIX
	     Search only files ending with SUFFIX, e.g.  ``.txt''.  May be specified multiple times.

     -i, --ignore-case
	     Ignore the case of old_string.

     -w, --whole-words
	     Make old_string match only on word boundaries.

     -b, --backup
	     Move the original files to filename~ before replacing them.

     -q, --quiet
	     Quiet mode.

     -v, --verbose
	     Verbose mode.

     -s, --dry-run
	     Simulation mode, no files are changed.

     -R, --recursive
	     Recurse into subdirectories.

     -e, --escape
	     Expand escape sequences in old_string and new_string.  Examples of escape sequences are '
' (new-line), '	' (tab), 'x42' (hexadec-
	     imal number 42), '33' (octal number 033).

     -p, --prompt
	     Prompt for confirmation before replacing each file.

     -f, --force
	     Ignore errors when trying to restore permissions and file ownership.

     -d, --keep-times
	     Keep modification times when replacing files.

     -t, --use-tmpdir
	     Use a temporary directory for storing temporary files, usually the value of the environment variable TMPDIR.  The default is to put
	     temporary files in the same directory as the file being modified.

     -a, --all
	     Do not ignore files and directories starting with .

IMPLEMENTATION NOTES

     An effort has been made to make the program behave as much as the original rpl as necessary.  Where it has been possible to make improve-
     ments, improvements have been made.  This implementation lacks many of the bugs in the original.

EXAMPLES

     Replace all occurences of ``F'' (on word boundaries) with ``A'' in all text files under the grades/ directory:
	   $ rpl -Rwd -x'.txt' 'F' 'A' grades/

SEE ALSO

     find(1), sed(1).

HISTORY

     This program was written for Debian as a free replacement for the non-free rpl program by Joe Laffey.
