在Linux中perl中轉義雙引號

Question

它不讓我在這裏使用Linux作爲操作系統回覆評論。 我正在使用下述內容獲取創建的票據，但-k參數，重複參數在「」中獲取消息，如果消息中有「」，則這些參數會混亂並且消息不會被轉發。 如何在-k參數中使用這些雙引號以便通過？ 在此先感謝

Answer 1

對我來說，引用殼插一個變量的最簡單方法是：

1. 括在''
2. 更換任何'與'"'"'

所以替換

$SEND_EVENT=`/opt/SendEvent/dist/SendEvent/SendEvent send -q "$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\"` ; 

與

(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\"` ; 

（做你的所有其他參數相同）。

或者，使用IPC :: System :: Simple :: capturex並傳遞數組中的所有參數。
