要解决awk在字符串匹配时出现误报的问题,如果该字符串是由sed命令插入的,可以尝试以下解决方法:
~来进行匹配,并使用\\转义特殊字符。echo "This is a string inserted by sed command" | awk '/This is a string inserted by sed command/ {print "Matched"}'
^和$来确保字符串的开始和结束。echo "This is a string inserted by sed command" | awk '/^This is a string inserted by sed command$/ {print "Matched"}'
index()函数来进行简单的子字符串匹配。echo "This is a string inserted by sed command" | awk 'index($0, "This is a string inserted by sed command") {print "Matched"}'
这些方法可以帮助你在awk中正确匹配由sed命令插入的字符串,避免误报的问题。
