Hi Pradhikshan

Any attempts from your side yet?
If not, to get you started, start playing around with these: (please do required changes yourself, eg: Desktop)

I'm not familiar with ksh, but these bash basics should work fine:
Code:
cd Desktop
ls
echo *
for this_file in *
do
	echo "$this_file"
	echo "more commands of yours"
	ls -l "$this_file"
done

SEARCH="this pattern"
grep --color=auto "$SEARCH" *
echo "$SEARCH" | sed s,"$SEARCH","new stuff",

If the following output pleases you, prefix '*' with -i
Code:
sed s,"$SEARCH","new stuff", *

Hope this helps

GIT-REPLACE(1)							    Git Manual							    GIT-REPLACE(1)

NAME
git-replace - Create, list, delete refs to replace objects SYNOPSIS
git replace [-f] <object> <replacement> git replace -d <object>... git replace -l [<pattern>] DESCRIPTION
Adds a replace reference in .git/refs/replace/ The name of the replace reference is the SHA1 of the object that is replaced. The content of the replace reference is the SHA1 of the replacement object. Unless -f is given, the replace reference must not yet exist in .git/refs/replace/ directory. Replacement references will be used by default by all git commands except those doing reachability traversal (prune, pack transfer and fsck). It is possible to disable use of replacement references for any command using the --no-replace-objects option just after git. For example if commit foo has been replaced by commit bar: $ git --no-replace-objects cat-file commit foo shows information about commit foo, while: $ git cat-file commit foo shows information about commit bar. The GIT_NO_REPLACE_OBJECTS environment variable can be set to achieve the same effect as the --no-replace-objects option. OPTIONS
-f If an existing replace ref for the same object exists, it will be overwritten (instead of failing). -d Delete existing replace refs for the given objects. -l <pattern> List replace refs for objects that match the given pattern (or all if no pattern is given). Typing "git replace" without arguments, also lists all replace refs. BUGS
Comparing blobs or trees that have been replaced with those that replace them will not work properly. And using git reset --hard to go back to a replaced commit will move the branch to the replacement commit instead of the replaced commit. There may be other problems when using git rev-list related to pending objects. And of course things may break if an object of one type is replaced by an object of another type (for example a blob replaced by a commit). SEE ALSO
