command-line

问题 Im trying to find the command to get the last modified date of a file in a local git repo. Created the repo and have done one commit. Had to edit one file and will commit this file but was wondering what the last modification data of the file in the repo is (not the commit date). Have no gui onl command line. git log ./path/to/filename.php only gives me the commit date 回答1: The correct way to do this is to use git log as follows. git log -1 --pretty="format:%ci" /path/to/repo/anyfile.any) -1

问题 How do you exclude a folder when performing file operations i.e. cp etc. I would currently use the wild card * to apply file operation to all, but I need to exclude one single folder. The command I'm actually wanting to use is chown to change the owner of all the files in a directory but I need to exclude one sub directory. 回答1: If you're using bash and enable extglob via shopt -s extglob then you can use !(<pattern>) to exclude the given pattern. 回答2: find dir_to_start -name dir_to_exclude

问题 So this doesn't seem like a terribly complicated question I have, but it's one I can't find the answer to. I'm confused about what the -p option does in Unix. I used it for a lab assignment while creating a subdirectory and then another subdirectory within that one. It looked like this: mkdir -p cmps012m/lab1 This is in a private directory with normal rights ( rlidwka ). Oh, and would someone mind giving a little explanation of what rlidwka means? I'm not a total noob to Unix, but I'm not

问题 According to run bash command in new shell and stay in new shell after this command executes, how can I run command: bash --rcfile <(echo "export PS1='> ' && ls") within golang? I've tried many combinations of exec.Command() but they did't work. For example: exec.Command("bash", "--rcfile", `<("echo 'ls'")`) I've also read this os, os/exec: using redirection symbol '<' '>' failed, but I think maybe my case is a bit more complicated. 回答1: You're almost there - I think the confusion is you're
