在Linux中perl中转义双引号

Question

它不让我在这里使用Linux作为操作系统回复评论。 我正在使用下述内容获取创建的票据，但-k参数，重复参数在“”中获取消息，如果消息中有“”，则这些参数会混乱并且消息不会被转发。 如何在-k参数中使用这些双引号以便通过？ 在此先感谢

Answer 1

对我来说，引用壳插一个变量的最简单方法是：

1. 括在''
2. 更换任何'与'"'"'

所以替换

$SEND_EVENT=`/opt/SendEvent/dist/SendEvent/SendEvent send -q "$TOOL" -a "$MSG_APPL" -n "$MSG_NODE_NAME" -p "$ESM_PROFILE" -s "$DSOM_SEV" -k "$DEDUPLICATION" -c "$MANAGEMENT_ID" -m "$LONG_TEXT" -t "ABC $SHORT_TEXT" -z "ABC" -y \"$DEFAULT_Q\"` ; 

与

(my $quoted_DEDUPLICATION = $DEDUPLICATION) =~ s/'/'"'"'/g; 
$SEND_EVENT=`/opt/SendEvent/dist/SendEvent/SendEvent send -q "$TOOL" -a "$MSG_APPL" -n "$MSG_NODE_NAME" -p "$ESM_PROFILE" -s "$DSOM_SEV" -k '$quoted_DEDUPLICATION' -c "$MANAGEMENT_ID" -m "$LONG_TEXT" -t "ABC $SHORT_TEXT" -z "ABC" -y \"$DEFAULT_Q\"` ; 

（做你的所有其他参数相同）。

或者，使用IPC :: System :: Simple :: capturex并传递数组中的所有参数。
