<p>Often I find myself needing to search for .R or or .Rmd files in which I have used a specific function. There are a variety of searches that you can do; however, I wanted something that would work recursively at the command line of a Linux or Mac terminal. I found the answer <a target="_blank" rel="nofollow" href="http://stackoverflow.com/a/28186178">here</a> and have modified it a bit so that it works as a function in Bash (in this example I search through .R and . Rmd files).</p>
<p>Add the following to your ~/.bash_aliases file and then source ~/.bashrc:</p>
<div>
<pre></pre>
<pre>findinRfun() {<br><br>if [ -z &quot;$1&quot; ]<br> then<br>    echo &quot;No argument supplied&quot;<br> else<br>    #search text is passed as argument $1<br>    find . -type f \( -name &quot;*.R&quot; -o -name &quot;*.Rmd&quot; -o -name &quot;*.r&quot; -o -name &quot;*.rmd&quot; \) -print0 | xargs --null grep --with-filename --line-number --no-messages --color --ignore-case &quot;$1&quot;<br>fi<br>            }<br><br>alias findinR=findinRfun<br><br></pre>
<p>Now, at the command line, you can search through all the files below the current location that contain your search text.</p>
<pre>findinR mysearchtext<br></pre>
