我有一个结构如下的文件：

 msgid ""
    msgstr ""
    "PO-Revision-Date: 2013-04-08 10:12:14+0000\n"
    "MIME-Version: 1.0\n"
    "Content-Type: text/plain; charset=UTF-8\n"
    "Content-Transfer-Encoding: 8bit\n"
    "Plural-Forms: nplurals=2; plural=n > 1;\n"
    "X-Generator: GlotPress/0.1\n"
    "Project-Id-Version: Modern Theme\n"

    #: 404.php:34
    msgid "Page not found"
    msgstr "Page non trouvée"

    #: alert-form.php:6
    msgid "You have sucessfully subscribed to the alert"
    msgstr "Vous vous êtes inscrit avec succès à cette alerte"

    #: alert-form.php:7 user-change_email.php:42
    msgid "Invalid email address"
    msgstr "Adresse e-mail incorrecte"

    #: alert-form.php:8
    msgid "There was a problem with the alert"
    msgstr "Il y a un problème avec cette alerte"

    #: alert-form.php:39
    msgid "Subscribe to this search"
    msgstr "Abonnez vous à cette recherche"

    #: alert-form.php:55
    msgid "Subscribe now"
    msgstr "Abonnez-vous maintenant"

    #: contact.php:35
    msgid "Contact us"
    msgstr "Contactez-nous"

我想交换包含字符串 msgid 的行的内容，在括号之间与内容，在包含 msgstr 的连续行上，在括号之间，您能给我提示编写脚本或通过命令执行吗线 ？

You can use awk and sed to do this. Following works.

awk '/msg.*/{getline x;print x;}1' file | sed -e 's/msgid/msgidt/g' -e 's/msgstr/msgid/g' -e 's/msgidt/msgstr/g'

awk swaps the lines that matches with the regex msg.* and pipe it to sed. First sed renames msgid to a temporary one msgidt and then renames msgstr to msgid and finally msgidt to msgid.

Result :

msgid ""
msgstr ""
"PO-Revision-Date: 2013-04-08 10:12:14+0000\n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"
"Plural-Forms: nplurals=2; plural=n > 1;\n"
"X-Generator: GlotPress/0.1\n"
"Project-Id-Version: Modern Theme\n"

#: 404.php:34
msgid "Page non trouvee"

msgstr "You have sucessfully subscribed to the alert"

#: alert-form.php:7 user-change_email.php:42

msgstr "Invalid email address"

#: alert-form.php:8
msgid "Il y a un problC(me avec cette alerte"
msgstr "There was a problem with the alert"

#: alert-form.php:39
msgid "Abonnez vous C  cette recherche"
