Useful unix command

Posted: April 11, 2013 in Linux
Tags: , , , , , ,

Lets write a simple unix command to list all java files which contains the word “sample”

 
find -nam "*.java" | xarg grep "sample" -ril

find -name “*.java” will search all the java files. “|” will be used to redirect the output of the first command to next , one by one. Now, in that we are searching for the word sample . -r is used to make a recursive search . -i is to make a Case Sensitive search and -l is used for listing the file names alone.
error

OOPS. something went wrong.. What was that ???? I mispelt name. What should i do now? rewrite the command ? Use up and arrow keys for editing the entire command.No need at all. When ever you want to replace something in your command stick to this pattern

^foo^bar

since we have mispelt name our command should be

^nam^name
