FIND & GREP
Basically FIND & GREP are the UNIX commands shared through
the FILTERS .Where is SED (STREAM) is one of the main
editor.
FIND : Find is an exclusive command used to find
files/folders are other information.and this is powerfull
then windows.
ex : # find /raja -name shekar -print
output : raja/shekar
Grep : This is also one of the important command used to
globally searching the regular expression in the file .
GERP is grepping the information character by character.
(i.e) from file .
ex 1) : #GREP "cat" raja
2) : #GREP -i "cat" raja (for case sensitive)
2) : #GREP -v "cat" raja (v represent negative )
OUTPUT :if we have an file raja with data regarding cat we
can clearly explain.
Finally SED (STREAM)
SED : It is an editor but non interactive .
ex : # sed -e 'd/chain/dog/f' raja > shekar
