awk中使用替换

http://blog.sina.com.cn/s/blog_71459fbc0101eq0h.html

gsub（/123/,456,$3）将第三个域中的“123”替换成“456”
例子：
test文件内容：
0001|efskjfdj|EREADFASDLKJCV
0002|djfksdaa|JDKFJALSDJFsddf
0003|efskjfdj|EREADFASDLKJCV
0004|djfksdaa1234|JDKFJALSDJFsddf
将文本以“|”分割，将第二域中的字母“d”替换成“#”
awk -F '|' 'gsub(/d/,"#",$2) {print $0}' test
0001 efskjf#j EREADFASDLKJCV
0002 #jfks#aa JDKFJALSDJFsddf
0003 efskjf#j EREADFASDLKJCV
0004 #jfks#aa1234 JDKFJALSDJFsddf
