我使用openssl生成以下列表
openssl ciphers 'ALL:eNULL'
结果：
ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:SRP-DSS-AES-256-CBC-SHA:SRP-RSA-AES-256-CBC-SHA:DHE-DSS-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-HA256:DHE-RSA-AES256-SHA:DHE-DSS-AES256-SHA:DHE-RSA-CAMELLIA256-SHA:DHE-DSS-CAMELLIA256-SHA:AECDH-AES256-SHA:SRP-AES-256-CBC-SHA:ADH-AES256-GCM-SHA384:ADH-AES256-SHA256:ADH-AES256-SHA:ADH-CAMELLIA256-SHA:ECDH-RSA-AES256-GCM-SHA384:ECDH-ECDSA-AES256-GCM-SHA384:ECDH-RSA-AES256-SHA384:ECDH-ECDSA-AES256-HA384:ECDH-RSA-AES256-SHA:ECDH-ECDSA-AES256-SHA:AES256-GCM-SHA384:AES256-SHA256:AES256-SHA:CAMELLIA256-SHA:PSK-AES256-CBC-SHA:ECDHE-RSA-DES-CBC3-SHA:ECDHE-ECDSA-DES-CBC3-SHA:SRP-DSS-3DES-EDE-CBC-SHA:SRP-RSA-3DES-EDE-CBC-SHA:EDH-RSA-DES-CBC3-SHA:EDH-DSS-DES-CBC3-SHA:AECDH-DES-CBC3-SHA:SRP-3DES-EDE-CBC-SHA:ADH-DES-CBC3-SHA:ECDH-RSA-DES-CBC3-SHA:ECDH-ECDSA-DES-CBC3-SHA:DES-CBC3-SHA:DES-CBC3-MD5:PSK-3DES-EDE-CBC-SHA:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:SRP-DSS-AES-128-CBC-SHA:SRP-RSA-AES-128-CBC-SHA:DHE-DSS-AES128-GCM-SHA256:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES128-SHA256:DHE-DSS-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA:DHE-RSA-SEED-SHA:DHE-DSS-SEED-SHA:DHE-RSA-CAMELLIA128-SHA:DHE-DSS-CAMELLIA128-SHA:AECDH-AES128-SHA:SRP-AES-128-CBC-SHA:ADH-AES128-GCM-SHA256:ADH-AES128-SHA256:ADH-AES128-SHA:ADH-SEED-SHA:ADH-CAMELLIA128-SHA:ECDH-RSA-AES128-GCM-SHA256:ECDH-ECDSA-AES128-GCM-SHA256:ECDH-RSA-AES128-SHA256:ECDH-ECDSA-AES128-SHA256:ECDH-RSA-AES128-SHA:ECDH-ECDSA-AES128-SHA:AES128-GCM-SHA256:AES128-SHA256:AES128-SHA:SEED-SHA:CAMELLIA128-SHA:IDEA-CBC-SHA:IDEA-CBC-MD5:RC2-CBC-MD5:PSK-AES128-CBC-SHA:ECDHE-RSA-RC4-SHA:ECDHE-ECDSA-RC4-SHA:AECDH-RC4-SHA:ADH-RC4-MD5:ECDH-RSA-RC4-SHA:ECDH-ECDSA-RC4-SHA:RC4-SHA:RC4-MD5

我想提取包含某些单词的所有条目，但我想用sed和ONE正则表达式来完成。我知道我也可以这样做：
openssl ciphers 'ALL:eNULL' | tr ":" "\n" | grep MYWORD |tr "\n" ":"
但我觉得有一种更简单的方式
答案 0 :(得分：2)
awk更适合这项工作：
openssl ciphers 'ALL:eNULL' | awk -v w=RC4 '!($0~w)' RS=':' ORS=':'
要使用搜索字符串获取所有单词：
openssl ciphers 'ALL:eNULL' | awk -v w=RC4 '($0~w)' RS=':' ORS=':'
RS=':'在输入字符串中将记录分隔符设为:，使每个记录显示在awk的单独记录中!($0~w)查找与w选项-v不匹配的所有记录
ORS=':'将输出记录分隔符设为: 答案 1 :(得分：0)
我想这给你需要的东西（WORD这里是RSA）：
openssl ciphers 'ALL:eNULL' |perl -pe 's/:/\n/g'| grep RSA | perl -lne 'push @a,$_;END{print join ":",@a}'
