我正在尋找一種理智的方式（我原先看過sed，但我認爲它很複雜），以啓用yum回購中的章節。在基於RHEL的系統上匹配後修改線路
我的木偶回購是：
[puppetlabs-products]
name=Puppet Labs Products El 7 - $basearch
baseurl=http://yum.puppetlabs.com/el/7/products/$basearch
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-puppetlabs
enabled=1
gpgcheck=1
[puppetlabs-deps]
name=Puppet Labs Dependencies El 7 - $basearch
baseurl=http://yum.puppetlabs.com/el/7/dependencies/$basearch
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-puppetlabs
enabled=1
gpgcheck=1
[puppetlabs-devel]
name=Puppet Labs Devel El 7 - $basearch
baseurl=http://yum.puppetlabs.com/el/7/devel/$basearch
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-puppetlabs
enabled=0
gpgcheck=1
[puppetlabs-products-source]
name=Puppet Labs Products El 7 - $basearch - Source
baseurl=http://yum.puppetlabs.com/el/7/products/SRPMS
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-puppetlabs
failovermethod=priority
enabled=0
gpgcheck=1
[puppetlabs-deps-source]
name=Puppet Labs Source Dependencies El 7 - $basearch - Source
baseurl=http://yum.puppetlabs.com/el/7/dependencies/SRPMS
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-puppetlabs
enabled=0
gpgcheck=1
[puppetlabs-devel-source]
name=Puppet Labs Devel El 7 - $basearch - Source
baseurl=http://yum.puppetlabs.com/el/7/devel/SRPMS
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-puppetlabs
enabled=0
gpgcheck=1
我希望能夠匹配（在這種情況下）[puppetlabs-devel]扔啓用標誌從0到1。在基於RHEL的系統中執行此操作的理想方式是什麼？這必須是一個自動化解決方案，因爲這是啓動腳本的一部分，應該沒有交互。
我這個捏造，但從來沒有真正能得到它的工作
cat /etc/yum.repos.d/puppetlabs.repo |awk '/\[puppetlabs-devel\]/{print;getline;$0="enabled=1"}1'
期望輸出
[puppetlabs-products]

謝謝。
根據輸入發佈預期輸出並解釋「RHEL based」系統是什麼，如果相關，或者刪除關於ti的文本（如果不相關）。 –
@EdMorton將在一分鐘後發佈輸出，如本系統中的RHEL，可以是Fedora，Redhat Linux，CentOS等 – ehime
