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.
