基于分隔符的合并记录-Linux

需要根据以下标准分析文件并创建新文件：

这是示例源数据

TTTTT001:866:           $READ #R1         FILE (TEST-ACCOUNTS) LOGICAL               00085100

TTTTT001-870-                                                                        00085500

TTTTT001-872-             MOVE 122 TO ERROR-ABEND-CODE                               00085700
TTTTT001-873-             PERFORM ZT-ERROR.                                          00085800

希望得到以下信息

每个部分由--（来自grep的结果）标识

删除显示在每行末尾的数字

拆下安装后的管路。直到--

合并从$READ开始的文本，直到。排成一行

所以输出应该是这样的

TTTTT001:866:           $READ #R1         FILE (TEST-ACCOUNTS) LOGICAL USING DESCRIPTOR (COMM-ACCOUNTS) STARTING FROM COMM-ACCOUNTS = WS-ACCT-KEY RECORD (TEST-ACCOUNTS) RELEASE(NO).
--
TTTTT001:1018:           $READ #R3         FILE (TEST-ACCOUNTS) ISN (R1-ISN) RECORD (TEST-ACCOUNTS) RELEASE (NO) HOLD.                    
--

您可以尝试此sed命令并获得确切的结果

sed -nr '/[T]+[0-9]+:/{:a;N;/\n--/{p;d;t};/\n.*\./{s/(.*) .*\n[^ ]+-(.*) .*/\1 \2/g;s/ +/ /g;p;d;t};s/(.*) .*\n[^ ]+-(.*) .*/\1 \2/g;s/ +/ /g; t a;}' FileName

将以下代码另存为

sed.in

，然后将文件名

sed-nr-f sed.in

。它适用于我的Ubuntu14.04和GNU-sed版本4.2.2上的示例输入

我已经在这个脚本中添加了注释，以防您想理解并根据自己的需要修改它。检查您是否想学习如何使用sed

s/[ \t]*[0-9]*$//;h         # remove trailing number and space, then save it to hold space
:back                       # label
n                           # next line
s/[ \t]*[0-9]*$//           # remove trailing number and space
s/TTTTT[^ ]*[ \t]+(.*$)/\1/ # remove heading and spaces
/\.$/ !{                    # if it's not the line end with '.', append it to hold space
    H
    bback                   # jump to label back
}
/\.$/ {                     # line end with '.'
    H                       # append
    :aa                     # label
    n                       # get next line
    /^--/ !baa              # if it's not line start with '--' skip it
    /^--/ {
        x                   # swap hold space and pattern space
        s/\n/ /g;p          # substitute \n with space and print it
        s/^.*$//            # empty pattern space
        x                   # swap space
        b                   # get into next cycle
    }
}

我看没有问题。。。
