问题 Does someone have an idea about how can I remove everything in R except one object? Normally, to remove everything I code: rm(list=ls()) So I tried: rm(c(list=ls()-my_object)) but it didn’t work. 回答1: The setdiff() function shows the difference between sets, so we can use this to give the difference between all the objects ( ls() ), and the object you want to keep. For example ## create some objects df <- data.frame() v <- as.numeric() # show everything in environment objects() # [1] "df" "v"

问题 I did: git init git add . git rm -rf dirname Looking at other answsers, git reset --hard HEAD , git checkout -f and git reflog did not work, apparently because there is no HEAD to go back to, nor a commit to get the files back from. Is there a way to get the files back? 回答1: There is no way. Usually, git rm checks the files have already been committed before deleting them, so you don't lose any of your work. However, using -f overrides this check. In short: Don't use -f . Don't touch anything

问题 Some program makes ta my root directory dummy files such as -1 -2 -3 ... -n I run unsuccessfully rm -1 and too rm "-1" Terminal thinks that -1 is the option. How can you remove the files in terminal? 回答1: You can use rm ./-1 , the ./ refers to the current directory and as the parameter doesn't start with a dash it isn't interpreted as an option. 回答2: As far as I recall adding -- as an option on the commandline will cause the rm command to consider all the remaining arguments literally, so the

问题 sorry if this is a noobie question but I can't find a good answer. To find then remove something I can use find . -name ".txt" -exec rm "{}" \; But why can't I just pipe the results to rm like find . -name ".txt" | rm like I would pipe it to grep find . -name ".txt" | grep a I've read from somewhere that rm doesn't take input from stdin and therefore I can't pipe it but what does that mean? When I type in rm a.txt it reads from standard input just like I can grep right? Or is there a

问题 I'm trying to work out a command which deletes sql files older than 15 days. The find part is working but not the rm. rm -f | find -L /usr/www2/bar/htdocs/foo/rsync/httpdocs/db_backups -type f \( -name '*.sql' \) -mtime +15 It kicks out a list of exactly the files I want deleted but is not deleting them.
