问题 I changed my root level password on phpMyAdmin. I was unsure where to enter the password itself, as it did not give me the option (login form). I wondered if it was the php.ini file but users with read privileges could read it if I placed the password in there. Now, the mysql doesn't run as I tried various online resources to fix the problem. If needs be I would delete mamp and re-install but I do not want to lose my database files. Ideally I would revert the password to default, which I

问题 Before marking this as duplicate, I went through these posts, but nothing helped. 'mvn' is not recognized as an internal or external command, Getting -bash: mvn: command not found, Can't access mvn command from command line? Some are specific to windows and did not help. A couple of them on Mac OS X gave suggestions, that I tried but did not help. What I tried (this is exactly what Maven suggests): Extract the distribution archive, i.e. apache-maven-3.1.1-bin.tar.gz to the directory you wish

问题 What is the benefit of using console.log vs console.info ? Or any of the other console commands for that matter? console.info("info"); console.error("error"); console.warn("warn"); vs console.log("log"); I thought it might change the color of the output or concatenate some sort of label, but they seem to all do the same thing. And according to the documentation here: https://nodejs.org/api/console.html#console_console_info_data they seem to all do the same as console.log 回答1: According to the

问题 When i unckeck the 'Use option as meta key' box in Settings, and then do Cmd + F (which i want to mean Meta + F for forward-word in bash) Terminal gives me a 'find word' popup, which isn't what i want. What i really want is for my Terminals to behave just like an xterm w.r.t. the key bindings. Is there any way to disable this popup and its binding? I know i could just use actual xterms, but for a variety of reasons i want to use Terminal. thanks in advance, Eric 回答1: The option as meta key

问题 I have many files, and I have to find a single line in these files and delete, and should be in terminal in linux. Anyone know how to do? Example FileSystem myFiles + file1 + file2 ... + file6500 The file aaa0 aaa1 .... fff9 回答1: This would delete that line in each file. for f in myFiles/*; do sed -i 'd/pattern that matches line that you want to delete/' $f done Alternatively you could use awk as well. tmp=$(mktemp) for f in myFiles/*; do awk '!/pattern that matches the line that you want to

问题 Im on mac and I have my terminal cursor set to the vertical bar option. However in vim command mode the cursor is the vertical bar but it wont let me use hjkl to go to the end of the line, it always stops right before the end. This is especially annoying because you have to use the arrow keys in insert mode to make the cursor go the end of the line. Any fix would be appreciated eg: hello worl | d , what I want is hello world | 回答1: I think you're looking for set virtualedit=onemore . From

问题 I want to make the following commands: cat > template.txt [enter in the terminal] text [Ctrl+d in the terminal] in a script. Is there a way to tell the script to do enter\Ctrl d? Is there a way to create a file and write to it in script? I didn't find anything that worked for me. Thanks. 回答1: A Here Document is kind of like a script version of what you're talking about, I think, although it is not entirely clear to me from your description. #!/bin/bash cat > template.txt <<- EOF Here is some

问题 With respect to this excellent post: What's the difference between nohup and a daemon? I would like to ask the following: After launching an application from my terminal, the application keeps running either in the background or the foreground and the only thing I can do to interact with it is by sending it signals from my terminal (given that stdin is still in place). However, after a daemon process is launched, I realized that it can be controlled with other means like querying it or
