rpm -q でパッケージ情報抽出

時々使うけども、毎回忘れてるので、ここにメモしておく。

背景

• インストール済みパッケージから各種情報を取得したかった

rpm -q ...

rpm -q --scripts

$ rpm -q --scripts jenkins

preinstall scriptlet (using /bin/sh):
/usr/sbin/groupadd -r jenkins &>/dev/null || :
# SUSE version had -o here, but in Fedora -o isn't allowed without -u
/usr/sbin/useradd -g jenkins -s /bin/false -r -c "Jenkins Continuous Build server" \
        -d "/var/lib/jenkins" jenkins &>/dev/null || :
postinstall scriptlet (using /bin/sh):
/sbin/chkconfig --add jenkins

# If we have an old hudson install, rename it to jenkins
if test -d /var/lib/hudson; then
    # leave a marker to indicate this came from Hudson.
    # could be useful down the road
    # This also ensures that the .??* wildcard matches something
    touch /var/lib/hudson/.moving-hudson
    mv -f /var/lib/hudson/* /var/lib/hudson/.??* /var/lib/jenkins
    rmdir /var/lib/hudson
    find /var/lib/jenkins -user hudson -exec chown jenkins {} + || true
fi
if test -d /var/run/hudson; then
    mv -f /var/run/hudson/* /var/run/jenkins
    rmdir /var/run/hudson
fi

# Ensure the right ownership on files
. /etc/sysconfig/jenkins
chown -R ${JENKINS_USER:-jenkins} /var/log/jenkins
chown -R ${JENKINS_USER:-jenkins} ${JENKINS_HOME:-/var/lib/jenkins}
preuninstall scriptlet (using /bin/sh):
if [ "$1" = 0 ] ; then
    # if this is uninstallation as opposed to upgrade, delete the service
    /sbin/service jenkins stop > /dev/null 2>&1
    /sbin/chkconfig --del jenkins
fi
exit 0
postuninstall scriptlet (using /bin/sh):
if [ "$1" -ge 1 ]; then
    /sbin/service jenkins condrestart > /dev/null 2>&1
fi
exit 0
