How to modify a file by using awk?
提问by Leo Chan
awk '/<ul>/ {ul++} ul == 6 { getline } 1' /var/www/html/INFOSEC/english/test.html
if i run this line of code, the shell will not help me to modify the file, instead, it only output the result in the shell. Can any one help???thx
如果我运行这行代码，shell 不会帮我修改文件，而是只在 shell 中输出结果。有人可以帮忙吗？？？thx

The simplest solution is to just send the output to a file; you might want to copy the file beforehand so you don't have to overwrite the file you're reading (which might otherwise lead to undesired behavior).
最简单的解决方案是将输出发送到文件；您可能希望事先复制文件，这样就不必覆盖正在读取的文件（否则可能会导致不良行为）。
cp test.html test.html.orig
awk 'your awk script here' test.html.orig >test.html
# and then optionally remove the copy:
rm test.html.orig
