WhichFile: Find a text string in files

In BrailleR: Improved Access for Blind Users

Find a text string in files

Description

Which files in a folder (and its subfolders) include/exclude a given text string

Usage

WhichFile(String, Folder, fixed = TRUE, DoesExist = TRUE)

Arguments

String	The text string or regular expression being sought.
Folder	The head folder to start searching in.
fixed	Fixed text string or if FALSE, a regular expression that will be passed togrep().
DoesExist	If TRUE, it shows the files that do include the text string of interest; if FALSE, files that lack the search string are returned.

Details

Finding a given search string in a pile of text files is time-consuming. Finding which files lack that search string is even harder.

Value

A vector of filenames returned as character strings.

Note

This search uses readLines() which throws plenty of warnings if the files being searched across do not all end in a blank line.
