命令模式
- /word :在光标之后查找一个字符word,按n向后继续搜索;
- ?word :在光标之前查找一个字符word,按n向前继续搜索;
- :n1,n2s/word1/word2/g :在n1和n2行之间查找word1并替换为word2,不加g则只替换每行的第一个word1;

例:
[root@bogon /]# cp /etc/dnsmasq.conf /tmp/1.txt
[root@bogon /]# vim /tmp/1.txt
/dnsmasq ?dnsmasq
# Configuration file for dnsmasq.
#
# Format is one option per line, legal options are the same
# as the long options legal on the command line. See
# "/usr/sbin/dnsmasq --help" or "man 8 dnsmasq" for details.
# Listen on this specific port instead of the standard DNS port
# (53). Setting this to zero completely disables DNS function,
# leaving only DHCP and/or TFTP.
#port=5353
# The following two options make you a better netizen, since they
# tell dnsmasq to filter out queries which the public DNS cannot
# answer, and which load the servers (especially the root servers)
# unnecessarily. If you have a dial-on-demand link they also stop
# these requests from bringing up the link unnecessarily.
# Never forward plain names (without a dot or domain part)
#domain-needed
# Never forward addresses in the non-routed address spaces.
#bogus-priv
# Uncomment these to enable DNSSEC validation and caching:
# (Requires dnsmasq to be built with DNSSEC option.)
#conf-file=%%PREFIX%%/share/dnsmasq/trust-anchors.conf
#dnssec
# Replies which are not DNSSEC signed may be legitimate, because the domain
# is unsigned, or may be forgeries. Setting this option tells dnsmasq to
# check that an unsigned reply is OK, by finding a secure proof that a DS
# record somewhere between the root and the domain does not exist.
# The cost of setting this is that even queries in unsigned domains will need
# one or more extra DNS queries to verify.
#dnssec-check-unsigned
# Uncomment this to filter useless windows-originated DNS requests
/dnsmasq
?dnsmasq
