use grep -c option

thanks for the reply. grep -c only Prints only a count of the lines that contain the pattern. i wanted the actual line and also the number of lines returned as well.

is there a way to check the length of a string in unix ?? i could possibly use this to see how many lines were returned.

Use AWK (nawk or /usr/xpg4/bin/awk on Solaris):

Code:

awk 'END{print c}/pattern/&&++c' input

line=$(grep -n "$pattern" "$filename" | cut -f1 -d':')
found=$(echo $line | awk '{print NF}'
