Helo buddy，使用awk只需执行以下操作：

awk '/name/{gsub("[\",]*", "");print $2}' yourFile.txt
致以最良好的祝愿！！；）

Helo buddy，和awk一起做吧：

awk '/name/{gsub("[\",]*", "");print $2}' yourFile.txt
致以最良好的祝愿！！；）

在这里也尝试以下awk解决方案

第一种方法：以防您需要在名称和值周围设置双航向

awk -F'[:,]' '/name/{sub(/^ +/,"",$2);print $2}'   Input_file
第二种方法：如果您只需要名称的值，那么以下方法可能会对您有所帮助

awk -F'[":,]' '/name/{print $5}'   Input_file
第一种方法的解释：只需将（：和，）作为字段分隔符，然后在包含字符串的行中查找字符串名称，然后将第二个字段的初始空格替换为NULL，然后打印第二个字段的值

第二种方法的解释：将（“：和，”）作为字段分隔符。然后在一行中搜索字符串名称（如果有），然后打印该行的第五个字段。

您应该解析JSON文件，而不是使用正则表达式

您可以使用Ruby执行以下操作：

$ ruby -0777 -r json -lane '
                   d=JSON.parse($_)
                  (d["cast"]+d["crew"]).each { |x| p x["name"] }' json
"Brian O'Halloran"
"Jason Mewes"
"Jeff Anderson"
"Kevin Smith"
"Richard J. Gasparian"
"Tristin Cole"
"Nadia Vurbenova"
"Simon Rodgers"
"Kevin Smith"
"Harvey Weinstein"
"Bob Weinstein"
或者，如果您想将演员与剧组分开：

$ ruby -0777 -r json -lane '
                   d=JSON.parse($_)
                   %w(cast crew).each {|w|
                   puts "#{w.capitalize}:"
                  (d[w]).each { |x| puts "\t#{x["name"]}" }}' json
Cast:
    Brian O'Halloran
    Jason Mewes
    Jeff Anderson
    Kevin Smith
Crew:
    Richard J. Gasparian
    Tristin Cole
    Nadia Vurbenova
    Simon Rodgers
    Kevin Smith
    Harvey Weinstein
    Bob Weinstein

这看起来像JSON-使用
jq
希望这不是一个家庭作业问题！如果你对使用python没问题的话，试试
grep-oE“name[^，]*，“|sed-e's/”//g'-e's/，//g'-awk-F:{print$2}”
。
cat x.json | python-c import sys，json；d=json.loads（sys.stdin.read（））；print（d[“cast”][1][id”]；
