copied!<p>There are two stages to this, firstly get all the files you want to edit into the argument list, then add the filename to the lines.</p> <p><b>1) Add files to argument list.</b></p> <p>Either start vim with "gvim *.txt" (if your shell can handle 700 files listed on the command line) or, load gvim with no files open (so the argument list is empty) and then:</p> <pre><code>cd /path/to/files " Get the list of files let filelist = glob('*.txt') " Add files to the argument list for file in split(filelist, '\n') exe 'argadd ' . file endfor </code></pre> <hr> <p><strong>EDIT:</strong></p> <p>A cleaner way of doing this is:</p> <pre><code>:cd /path/to/files :exe 'args' glob('*.txt') </code></pre> <p><strong>END OF EDIT</strong></p> <hr> <p><b>2) Do the required filtering on all files:</b></p> <pre><code>:argdo %s/^/\=expand('%:t') . ' '/ | w </code></pre> <p><b>Explanation:</b></p> <p><b><code>argdo</code></b> runs the command on every file in the argument list.</p> <p><b><code>%s/FROM/TO/</code></b> replaces FROM with TO</p> <p><b><code>^</code></b> is the start of the line (so the replacement adds TO to the start of the line)</p> <p><b><code>\=</code></b> means that TO should be the result of an expression</p> <p><b><code>expand('%:t')</code></b> gives the name of the current file (%), only including the tail (':t'), so no leading directory name.</p> <p><b><code>. ' '</code></b> appends a space.</p> <p><b><code>|</code></b> is the command joining character, so after the substitution, it runs:</p> <p><b><code>w</code></b>, which writes the file to disk.</p>
