问题 I use a Git repository on my server to version user data files sent to the server. I'm interested in getting a list of changed files between any two revisions. I know about git diff --name-only <rev1> <rev2> , but this only gives me a list of file names. I'm especially interested in renames and copies, too. Ideally, the output would be something like this: updated: userData.txt renamed: picture.jpg -> background.jpg copied: song.mp3 -> song.mp3.bkp Is it possible? --name-status also doesn't

问题 How to list all the files which match a certain pattern inside a user specified directory? This should work recursively inside the sub folders of the selected directory. I also need a convenient way(like tree control) of listing them. 回答1: It appears that a couple answers talk about recursion, and one about regex. Here's some code that puts the two topics together.

There is a solution

R list files with multiple conditions

问题 I want to list all files in a directory that met certain conditions (date and currency). So with only one condition the argument pattern in list.files works well: file.ls <- list.files(path='~/DATA/PiP/Curvas/',pattern='20130801') For multiple conditions I've tried: file.ls <- list.files(path='~/DATA/PiP/Curvas/',pattern=c('20130801','USD')) But had the same result as the first one. Is there a way to have multiple criteria in pattern argument of list.files ? 回答1: Filter(function(x) grepl("USD
