Latexian Help > Batch Find
The Batch Find panel allows you to search all of your files in a single step, including all files that are part of an open project. To open the Batch Find panel, select "Batch Find" from the "Find" menu. In the panel, you will see text boxes to enter find text (which may be a Regular Expression), file expressions to limit the search to particular files, and replace text. After entering find text, you can click "Find" to perform the search. For a large number of files, the search may take awhile, but you can continue editing your files as the search is in progress. When you select the Batch Find panel, the search results will automatically update to reflect any changes you have made to files.
File Expressions are Regular Expressions that allow you to limit a search to files having certain file names. The screenshot above shows an example where only files ending with ".tex" were included in the search. A preference option is available that determines whether File Expressions are simple or complex regular expressions. See the Regular Expressions Help Topic for more details.
