If this is a stand-alone change (that is not part of a bigger program)
then you can use the following:

perl -i -p -e 's/Einat/Shalom/g' Temp.c

though maybe you need a more specilized pattern
perl -i -p -e 's/Print "Einat";/Print "Shalom";/g'

and if you want to create backup with a .bak extension for the 
original file then use

perl -i.bak ....

and if you are on windows then you are bit out of luck as you'll
have to replace ' by " and your'll have to escape the internal "
characters by \"
