インドでの入学時期です。私は、最高の大学を目指して頑張っています。
私は次のような表を含むPDFファイルを持っています
約2500以上のエントリがあり、3日間の時間があります。
だから私にとって適切な大学を分類するいくつかのスマートな仕事をするために、私は内容を複数の正規表現に一致させる必要があります。
[0-9]{5,}
私は最初にそれをlibreoffice calc
が開きますがlibreoffice Draw
。私はpdftohtml
とpdftotext
を試しましたが、どちらもひどく混乱しています。
最後に私はpdfgrep
に来ましたが、grepと組み合わせて機能しません。
pdfgrep regexp1 ./locn to file|grep regexp2|grep regexp3
エラーを与える
Binary file (standard input) matches
したがって、私がしなければならないことは、pdfgrepに配置する単一の正規表現を使用することです。これは、必要なすべての正規表現に一致します。
編集:PDFをダウンロードできます ここ。
pdfgrep
は行ではなくページで機能するため、.*
の代わりに何でも一致させる必要があります。改行以外のすべてと一致させるには[^\n]*
が必要であり、同じ行に一致することを確認してください。何らかの理由で、[\n]
はn
によってpdfgrep
(\
は無視されます)として扱われるため、いくつかのトリックが必要です。これを試して:
pdfgrep '(Computer|Information)'[^$'\n']'*GE'[^$'\n']*'FALSE'[^$'\n']*'[0-9]{5,}' Closing_Rank_After_Round_III.pdf
私のシステムでは、これは82行を返します。

$'\n'
は ANSI Cエスケープシーケンス と呼ばれます。これらは、特定の問題のある文字(非印刷文字や引用符など)を、他の方法では認識できないプログラムに指定するための、移植可能で堅牢な方法です。この場合、それらを 文字クラス で使用しています。文字クラスが^
で始まる場合は、「このクラスの文字を除くすべてのものに一致する以外です。したがって、[^$'\n']
は「改行文字以外のすべてに一致」これにより、werが探している一致がすべて同じ行にあることが保証されます。
それが言っているのは、ストリームのどこかに「バイナリ」があるということです。
多分試してください:
pdfgrep regexp1 ./locn to file|grep --text regexp2|grep --text regexp3
または、strings
を使用してみてください:
文字列のマニュアルによると、
For each file given, GNU strings prints the printable character sequences that are at least 4 characters long (or the number given with the options below) and are followed by an unprintable character. By default, it only prints the strings from the initialized and loaded sections of object files; for other types of files, it prints the strings from the whole file. strings is mainly useful for determining the contents of non-text files.
