How to read multiple lines with awk
- Thread starter pnut
- Start date
- Thread starter
- #2
I found the answer, in case anyone else has hit the same stumbling block, here it is. <br>
This script will print the line in which the string is found and 2 lines after. Variables can be adjusted to print n # of lines. My search was for the first field only, however this can also be adjusted. Have fun and God bless.<br>
<br>
awk '<br>
BEGIN {<br>
flag = 0;<br>
count = 0;<br>
limit = 3<br>
}<br>
{<br>
if (( flag == 0 ) && ( $1 == "string" ))<br>
#<br>
flag=1<br>
#<br>
if (flag > 0)<br>
{<br>
++count<br>
print<br>
}<br>
if ( count >= limit )<br>
{<br>
flag=0<br>
count=0<br>
}<br>
} ' filename
