Write a shell script that searches the file contents in a directory and its sub-directories for a text string given by the user. It list all such file names having that given string and store in a temp file “search_temp”. It should have user friendly messages e.g. “File does not exit” , “Do you want to search again”, etc.
#bin/bashread-p”Enter a filename:”filename if[[ -f $ Search_temp]] ; then echo “The file $ Search_temp exists.”read –p “Enter the you word want to find:” Word grep “$word” “$Search_temp” else echo “The file $filename does not exist “. fi SUCCESS=0 E_NOARGS=65 If [-z”$1″] then echo”Usage:basename $0’rpm-file” exist $E_NOARGS fi { #Begin code block. echo echo”Archive Description:” rpm-qpi $ 1 # Query descri…. echo echo”Archive Listing:” rpm-qpl $ 1 # Query listing echo rpm-i—test $ 1 # Query whether rpm file can be installed.
