\chapter{Files}

\section{Remove Part of a Filename from Multiple Files}

\lettrine{S}{ome} applications can produce files that are similarly named, and for whatever reason, you want to remove the repetitive bits. You can use the \texttt{mmv}\index{mmv} package to do this. Assume you have a list of files that all start with ``foo'':

\begin{Verbatim}[]
foo143.txt
fooabi.txt
foo38r.txt
\end{Verbatim}

\lettrine{T}{his} can also be accomplished by using the \textbf{rename}\index{rename} command.

\section{Obtain a List of Files and their Paths}

\lettrine{T}{he} \texttt{find} command has options to obtain this list. To obtain this list with the full path, use:

\input{bits/find_PWD}

To obtain this list with a relative path, use:

\begin{Verbatim}[]
find .
\end{Verbatim}

\ktcbox{Sometimes you need a list of files with their filepaths, and these tools will do that. Unfortunately, Linux does not have a way to put the file first, so the way to do this is to redirect \texttt{stdout} to a \texttt{.csv} file and manipulate the output in a spreadsheet.}
