One-liners appreciated. (And just as an additional note, this is to be used in parcellite actions.) $ cat titles.txt purple haze Somebody To Love fire on the mountain THE SONG REMAINS THE SAME Watch the

嵌入式Qt应用程序进行中文显示有两种解决方案，一种是直接在代码中使用中文，利用QTextCodec类来实现，另一种是使用qt平台的国际化支持机制，通过语言翻译来实现。第一种方案直接明了，相对来说也简单方便一点，除了编码时麻烦点（来回切换输入法），而第二种方法的优点是具有良好的扩展性，代码中全部使用英文，然后使用中文翻译文件来进行语言翻译，当需要其它语言方案时，只需要添加翻译文件就可以。这里先介绍第一种方案，之后再写第二方案的文章。 方案实现 直接使用中文，利用QTextCodec类来实现中文的显示方案实现通过下面的三个步骤： 中文字体文件的存在：前文提到过字体文件的内容，文泉驿字体库是支持中文的。 应用程序代码中QTextCodec的设置和QFont字体的设置：对整个应用程序来说，一般是放在main函数中进行设置，大概的代码如下： int main(int argc, char *argv[]) { QApplication app(argc,argv); ... QTextCodec* codec = QTextCodec::codecForName("UTF-8"); app.setFont(QFont("wenquanyi",16,75,FALSE,QFont::Unicode)); app.setDefaultCodec(codec); ... return app

A console program (translate-shell) has an output with colors and uses special decorate characters for this: ^[[22m, ^[[24m, ^[[1m... and so on. I'd like to remove them to get a plain text. I tried with tr -d "^[[22m" and with sed 's/[\^[[22m]//g', but only is removed the number, not the special character ^[ Thanks. tuxdna You have multiple options: https://unix.stackexchange.com/questions/14684/removing-control-chars-including-console-codes-colours-from-script-output http://www.commandlinefu.com/commands/view/3584/remove-color-codes-special-characters-with-sed and as -no-ansi as pointed out

This question already has an answer here: Remove non-ASCII characters from CSV 11 answers I am trying to manipulate a text file and remove non-ASCII characters from the text. I don't want to remove the line. I only want to remove the offending characters. I am trying to get the following expression to work: sed '/[\x80-\xFF]/d' The suggested solutions may fail with specific version of sed, e.g. GNU sed 4.2.1. Using tr : tr -cd '[:print:]' < yourfile.txt This will remove any characters not in [\x20-\x7e] . If you want to keep e.g. line feeds, just add \n : tr -cd '[:print:]\n' < yourfile.txt If

I would like to use the tr command to replace all occurrences of the string "\n" with a new line (\n). I tried tr '\\n' '\n' but this just seems to match any '\' and any 'n' Here's how to do it with sed : sed 's/\\n/\n/g' Example usage: To replace all occurrences of \n in a file in-place: sed -i 's/\\n/\n/g' input_filename To replace all occurrences of \n through a pipe, and save into another file cat file1 file2 file3 file4 | sed 's/\\n/\n/g' > output_file 来源： https://stackoverflow.com/questions/13610639/tr-command-how-to-replace-the-string-n-with-an-actual-newline-n

This is the command I'm using on a standard web page I wget from a web site. tr '<' '\n<' < index.html however it giving me newlines, but not adding the left broket in again. e.g. echo "<hello><world>" | tr '<' '\n<' returns (blank line which is fine) hello> world> instead of (blank line or not) <hello> <world> What's wrong? That's because tr only does character-for-character substitution (or deletion). Try sed instead. echo '<hello><world>' | sed -e 's/</\n&/g' Or awk . echo '<hello><world>' | awk '{gsub(/</,"\n<",$0)}1' Or perl . echo '<hello><world>' | perl -pe 's/</\n</g' Or ruby . echo '

I have a lot of text in lowercase, only problem is, that there is a lot of special characters, which I want to remove it all with numbers too. Next command it's not strong enough: tr -cd '[alpha]\n ' In case of éćščž and some others it returns "?" But I want to remove all of them. Is there any stronger command? I use linux mint 4.3.8(1)-release You can use tr to print only the printable characters from a string like below. Just use the below command on your input file. tr -cd "[:print:]\n" < file1 The flag -d is meant to the delete the character sets defined in the arguments on the input
