怎么財能把文件中的中文去掉呢

heyj6969

假如有這么一個文件 add-remove.txt 里面有這么數(shù)據(jù)
msgid ""
"View fail!\n"
"The infofile of '%s' was broken."
msgstr ""
"查看失��！\n"
"“%s”的描述文件被損壞。"

msgid "View the detailed information about the selected ap/patch"
msgstr "查看選中的程序或補丁的詳細信息"

msgid ""
"What this %s is dependent on was/were lacked,you need to add dependencies "
"first.\n"
"Dependencies:%s\n"
"Continue to add?"
msgstr ""
"未檢測到這個%s所依賴的程序或補丁，你需要先安裝它們。\n"
"依賴:\n"
"是否繼續(xù)安裝？"

===================

我要把其中的中文去掉  該怎么做呢，shell  或 C 也行

blacknew

sed 's/[^ -~]//g' add-remove.txt

用C很方便。首先確定編碼，然后根據(jù)該編碼中中文字符范圍，按字節(jié)讀按字節(jié)判斷就成了。

blackold

方法與編碼有關(guān)。

    這樣 只剩下些
"% '%-%'  !"
"“%-%” "

""
"%   !(%-%)\"
":%-%\"
"   ,     ."
""
"%(%-%)\"
"%-%\"
""
這樣不合要求哦

    這條命令跟文件的編碼有關(guān)的吧
我執(zhí)行了這條命令 出現(xiàn)
sed: -e 表達式 #1, 字符 16: Invalid collation character↵
請問是怎么回事呢

我的文件編碼
--enca add-remove.po
--Universal transformation format 8 bits; UTF-8

heyj6969

聽了為大蝦的  這樣就可以了
$ LANG=UTF-8 sed -e 's/[\x80-\xff]*//g' add-remove.txt

還是要感謝各位 謝謝咯
