Script to search a word/Parameter from file and append.

 In this post, i wanted to write a shell script to search a parameter/Word in a file and append the value if the word/parameter is not there in the file.

#!/bin/bash

 grep -i "Pasupula" /tmp/Sravan/info.txt

if [ $? == 0 ]

then

        echo " Already search content was there in the file"

else

        echo -e " Sravanakumar_Pasupula from bangalore" >> /tmp/Sravan/info.txt

fi

 here, info.txt is a file, under which i wanted to search a word "Pasupula", if the word is exists in the file nothing to append, if the word is not there in the file then execute the command by appending the Sravanakumar_Pasupula from Bangalore.
