Question

我正在尝试从文件（output.txt）中读取，从每行中提取文件名中的票号并添加到该行的末尾。

难点在于，票号可能是任何类型的号码，并且有些号码不被视为票号而且没有固定的格式。

但我所知道的是，在门票号码之前，它通常有_或.，后面总是_

例如：

SM-10880B1
LSUFE-583B1
PCRF-17717B1
REQUEST-6771B1
SM-10507B1
ECS-6870B1

示例文件名

    patch_SW_9.3.0.SM-10880B1_HW_client_x86_64.jar
    patch_SW_9.3.1.LSUFE-583B1_x86_64.jar
    patch_SW_9.3.0_PCRF-17717B1_x86_64.jar
    patch_SW_9.3.0_REQUEST-6771B1_i86pc.jar

    patch_FW_9.3.0.1B_x86_64.jar  <-- not to extract, 1B is not the ticket number
    patch_SW_4.2.1_5B1_x86_64.jar <-- not to extract, 5B1 is not the ticket number
    patch_SW_9.3.0.ServicePackB1_x86_64.jar <-- not to extract, ServicePackB1 is not the ticket number

Answer 1

将语法限制为POSIX，您可以使用expr text : regex表达式来解析行中的tickets，然后写出有效票证的每个line逗号','和ticket。例如：

#!/bin/sh

while read line; do
    new=$(expr "$line" : "^.*[_.]\([A-Z]*[-][a-zA-Z0-9]*\)_.*$")
    [ -n "$new" ] && printf "%s,%s\n" "$line" "$new"
done <"$1"

exit 0
