使用sed或awk在特定行的末尾添加引号(")

Question

我有一个120 K的文本，类似于下面的文本，我想在用lr:完成的行的末尾添加“(引号)”。请告诉我如何使用sed或awk来完成它。

HSS-ServiceProfile=consumer_mmtel_d426s6
    hss-Trigger2ApplicationServers="42601:sip\\:d426s6mtasorig.routingcore.imsw..it;call=orig;lr:
    hss-Trigger2ApplicationServers="42603:sip\\:d426s6mtasorig.routingcore.imsw..it;call=orig;lr:
    hss-Trigger2ApplicationServers="42605:sip\\:d426s6mtastermrg.routingcore.imsw..it;call=term;lr:
    hss-Trigger2ApplicationServers="42607:sip\\:d426s6mtastermnr.routingcore.imsw..it;call=term;lr:
    hss-DefaultApplicationServer="sip:d426s6mtasorig.routingcore.imsw..it;lr"
    hss-DefaultASHandling="SESSION_CONTINUED"
    hss-DsaiCapability=false

告诉sed用它自己替换行尾的lr:加上双引号：

sed -e 's/lr:$/&"/'
#            ^ ^
#            | |
#      End of  |
#       line   The whole
#              matching part
