怎么财能把文件中的中文去掉呢

heyj6969

假如有这么一个文件 add-remove.txt 里面有这么数据
msgid ""
"View fail!\n"
"The infofile of '%s' was broken."
msgstr ""
"查看失败！\n"
"“%s”的描述文件被损坏。"

msgid "View the detailed information about the selected ap/patch"
msgstr "查看选中的程序或补丁的详细信息"

msgid ""
"What this %s is dependent on was/were lacked,you need to add dependencies "
"first.\n"
"Dependencies:%s\n"
"Continue to add?"
msgstr ""
"未检测到这个%s所依赖的程序或补丁，你需要先安装它们。\n"
"依赖:\n"
"是否继续安装？"

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

我要把其中的中文去掉  该怎么做呢，shell  或 C 也行

blacknew

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

kwokcn

用C很方便。首先确定编码，然后根据该编码中中文字符范围，按字节读按字节判断就成了。

blackold

方法与编码有关。

    这样 只剩下些
"% '%-%'  !"
"“%-%” "

""
"%   !(%-%)\"
":%-%\"
"   ,     ."
""
"%(%-%)\"
"%-%\"
""
这样不合要求哦

    这条命令跟文件的编码有关的吧
我执行了这条命令 出现
sed: -e 表达式 #1, 字符 16: Invalid collation character↵
请问是怎么回事呢

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

heyj6969

听了为大虾的  这样就可以了
$ LANG=UTF-8 sed -e 's/[\x80-\xff]*//g' add-remove.txt

还是要感谢各位 谢谢咯
