grep first match

# Basic syntax:
grep -m 1 "pattern" input_file.txt
# Where -m is the maximum number of matching lines to return, i.e. stop
#	reading the file after m matches
# Note, this is more efficient than piping to head because there you
#	always read the whole file even if you're only looking for m matches

                                    Just use flag -m to define number of occurrences to match:
grep -m1 pattern file

                                    Just combine grep with head command for filtering  only the first match as:
grep &quot;match&quot; | head -n 1   #Change 1 to not only match first but further matches

                                    #Combine grep and tail for grepping until second match and filtering 
#last with tail command
grep -m2 &quot;two&quot; in-file.txt | tail -n1
