Question

我想检查第1列中的数字是否等于第2列，最后第1列应以"ABC"开头，以"DEF"结尾，但有时也会以{{1}结尾"DEFZ#"或"ABC"######"DEF"之间的数字应与第二列匹配。请有人帮我。

我的意见

"DEFZ#"

输出应为：

ABC12345DEF|12345|23132331331|
ABC12345DEFZ1|12345|23132331331|
ABC12345DEFZ2|12345|23132331331|
ABC95678DEF|45678|23132331331| 
ABC87887DEF|86187|23132331331|
ABC89043DEF|89043|23132331331|
ABC89043DEFZ1|89043|23132331331|
ABC89043DEFZ2|89043|23132331331|
ABC89043DEFZ3|89043|23132331331|

我试图使用以下内容，但它无效

ABC12345DEF|12345|23132331331|
ABC12345DEFZ1|12345|23132331331|
ABC12345DEFZ2|12345|23132331331|
ABC89043DEFZ1|89043|23132331331|    
ABC89043DEFZ2|89043|23132331331|
ABC89043DEFZ3|89043|23132331331|

有人可以帮我吗？提前致谢

awk -v FS="|" '{                  # call awk set field separator |
                 tmpvar = $1;     # save first field contents in variable tmpvar

                 # substitute first ABC or DEF 
                 # which can be followed by Z and numbers 
                 # from variable with null globally
                 # so that tmpvar will just have numbers which is between abc and def*
                 gsub(/^ABC|DEF(Z[0-9]+)?$/,"",tmpvar)
               } 
               # if tmpvar is equal to second field then
               # print current record/row/line, thats boolean true, print $0
               tmpvar == $2
              ' infile

Online regex

/^ABC|DEF(Z[0-9]+)?/第一替代^ABC ^断言字符串ABC开头的位置字面匹配字符ABC（区分大小写）
第二个替代DEF(Z[0-9]+)? DEF字面匹配字符DEF（区分大小写）第一个捕获组(Z[0-9]+)? ?量词 - 零和之间的匹配一次，尽可能多次，根据需要回馈（贪婪）Z字面匹配字符Z（区分大小写）匹配下面列表中的单个字符[0-9]+
+量词 - 在一次和无限次之间匹配，尽可能多次，根据需要回馈（贪婪）
