<h1><a name="grep">GREP: Search Files for Pattern</a> </h1> <p><strong>grep</strong> is used to search for strings in multiple files. Digital Mars grep is handy because it's fast, will search system and hidden files, will search for wide characters strings, and will search binary files.</p> <h3>Command syntax:</h3> <pre><strong>grep</strong> [<em>switches</em>] <em>pattern</em> { <em>file</em> } </pre> <dl> <dt><em>pattern</em></dt> <dd>the string to search for.</dd> <dt><em>file</em></dt> <dd>the name of the file to search. Multiple files can be listed, and wildcards can be used.</dd> <dt><strong>-h</strong></dt> <dd>Suppress printing of filenames.</dd> <dt><strong>-i</strong></dt> <dd>Become case-insensitive.</dd> <dt><strong>-r</strong></dt> <dd>Recursively search subdirectories. </dd> <dt><strong>-v</strong></dt> <dd>Verbose; print name of each subdirectory as it is searched.</dd> <dt><strong>-z</strong></dt> <dd>Search for wide character strings.</dd> </dl> <p><strong>grep</strong> will print each line in each file that contains a match for <em>pattern</em>. It works with binary files as well as text files.</p> <h3>Example:</h3> <p>To search all .c files for the string 'this':</p> <pre>grep this *.c </pre> <p>To find which library file is the one to link for FindFirstFile():</p> <pre>grep -i findfirstfile \dm\lib\*.* </pre> </div> <div id="footernav"> <a href="https://www.digitalmars.com/" title="digitalmars.com">Home</a> | <a href="/index.cgi/contrast/https://digitalmars.com/ctg/../rtl/rtl.html" title="Runtime Library Reference">Runtime Library</a> | <a href="/index.cgi/contrast/https://digitalmars.com/ctg/../ugr/ugr.html" title="IDDE Reference">IDDE Reference</a> | <a href="/index.cgi/contrast/https://digitalmars.com/ctg/../stl/index.html" title="Standard Template Library">STL</a> | <a href="https://www.digitalmars.com/advancedsearch.html" title="Search Digital Mars web site">Search</a> | <a href="https://www.digitalmars.com//download/freecompiler.html" title="download C++">Download</a> | <a href="https://www.digitalmars.com/NewsGroup.html" title="Forums">Forums</a> </div> <div id="copyright"> Copyright © 1999-2018 by Digital Mars ®, All Rights Reserved | Page generated by <a href="https://dlang.org/spec/ddoc.html">Ddoc</a>. </div> </div><div class="naked_ctrl"> <form action="/index.cgi/contrast" method="get" name="gate"> <p><a href="http://altstyle.alfasado.net">AltStyle</a> によって変換されたページ <a href="https://digitalmars.com/ctg/grep.html">(->オリジナル)</a> / <label>アドレス: <input type="text" name="naked_post_url" value="https://digitalmars.com/ctg/grep.html" size="22" /></label> <label>モード: <select name="naked_post_mode"> <option value="default">デフォルト</option> <option value="speech">音声ブラウザ</option> <option value="ruby">ルビ付き</option> <option value="contrast" selected="selected">配色反転</option> <option value="larger-text">文字拡大</option> <option value="mobile">モバイル</option> </select> <input type="submit" value="表示" /> </p> </form> </div> </body> </html>
