I want to count the number of words and print the matched pattern lines which matches exactly with following pattern:

abc-ERROR:

The input File contains: 

# abc-ERROR: xyxxkkfgfr
# def-Error: aaaaaa
# abc-ERROR.cpp

The output should be:

 1   (count)
 # abc-ERROR: xyxxkkfgfr   (line)

You can use grep to get the lines and grep -c to get the number of lines. If you do not like running grep two times, you can use tee and the process substitution (the following is the bash syntax):

grep abc-ERROR: input.txt | tee >( wc -l )

How is this:

$ cat file
# abc-ERROR: xyxxkkfgfr
# abc-ERROR: xyxxkkfgfr
# abc-ERROR: xyxxkkfgfr
# def-Error: aaaaaa
# abc-ERROR.cp
# abc-ERROR: asdgsdgaaf
# abc-ERROR: asdgsdgaaf
# abc-ERROR: tttttttttq

$ awk '/abc-ERROR: /{a[$0]++}END{for(k in a) printf "%d\t(count)\n%s\t(line)\n",a[k],k}' file
1   (count)
# abc-ERROR: tttttttttq (line)
2   (count)
# abc-ERROR: asdgsdgaaf (line)
3   (count)
# abc-ERROR: xyxxkkfgfr (line)
