Searching Inside Files
Find every line of a file that contains a word.
grep searches inside files and prints every line that contains what you asked for. The name comes from an old text-editor command, g/re/p, and once you know grep you will use it forever.
Read it as: in shopping.txt, show me the lines containing an a. Notice it prints whole lines, not just the matching letter.
If nothing matches, grep prints nothing at all: no news is good news. Add -i to ignore capital letters, or -n to number the lines it found.
grep "a" shopping.txtLines containing an a.grep -i "MILK" shopping.txtIgnore capitals.grep -n "bread" shopping.txtShow line numbers too.Your task
