问题 I'm using Python in Terminal on Mac OSX latest. When I press enter, it processes the code I've entered, and I am unable to figure out how to add an additional line of code e.g. for a basic loop. 回答1: In the python shell, if you are typing code that allows for continuation, pressing enter once should not execute the code... The python prompt looks like this: >>> If you start a for loop or type something where python expects more from you the prompt should change to an elipse. For example: >>>

问题 I'm developing something in Livecode and I have been experimenting with using Mavericks own in-built php server. I started the server by sending the following command through shell... php -S localhost:8000 This enabled PHP to run successfully through localhost:8000/ However, I can not work out how to stop/disable PHP now in order to continue testing starting it - when I previously started PHP through the terminal I was able to do ctrl+c to stop php running but since I do not yet know how to

问题 Every time I open a new Terminal window I see the following. -bash: /Users/tim/.profile: No such file or directory I have no idea why this is happening or where to look to fix it; my profile is located at /Users/tim/.bash_profile not /Users/tim/.profile Any thoughts on how to troubleshoot this? 回答1: This happened to me as well and I noticed that at the top of my .bash_profile it had: source ~/.profile My understanding is that on MacOS / OS X .bash_profile is given priority over .profile so

问题 How would one copy only the first x lines of a csv file into a new csv file via the terminal? 回答1: Brief (You'll use a linux terminal/console) Use head -n NUMBEROFLINES file.csv to get the first NUMBEROFLINES of lines. Write it into another file using shell redirection ( > ) like this: head -n NUMBEROFLINES file.csv > mynewfile.csv Note that this will totally recreate mynewfile.csv , if it had any content before it is now deleted forever (-ish). If you ever happen to want the opposite ( last

问题 Does anyone know of a JS-based terminal client? Either something that initiates an SSH connection with a remote host or even something that simply communicates with a remote PHP script to execute commands and retrieve output. Does such a thing exist? 回答1: Check Anyterm, it uses a XmlHttpRequest channel to communicate with a daemon that uses a pseudo-terminal to communicate with a shell or other application. 回答2: http://www.masswerk.at/termlib/ looks interesting as a base. 回答3: http:/

问题 I'm reading data from 9 different sensors for my robot and I need to display them all steadily, in the same window so I can compare the values and see if any of the readings is off. The problem I'm having with both Serial.print and lcd.print is that the values are constantly moving and I can't really have a good look at them while moving the robot. I was thinking to call something like Serial.clear() before displaying anything else and that would just keep things steady and in one place,

问题 I have a bash script which generates a motd. The problem is depending on some terminal settings which I am not sure about the color will extend to the end of the line. Othertimes it doesn't: e.g. v.s. IIRC one is just the normal gnome-terminal and the other is my tmux term. So my question is how can I get this to extend to 80 character (or really to the terminal width). Of course I can pad to 80 chars but that really doesn't solve the problem. Here is a snip of my code which generates the

问题 What I'm looking for is a counterpart to file -I (Darwin; -i on Linux). For example, given: $ file -I filename.pdf filename.pdf: application/octet-stream; charset=binary I would like to be able to do something like this: $ [someCommand] filename.pdf application/pdf The result would be that filename.pdf would then be typed as application/pdf. The reason for the question is that sometimes web servers use the wrong MIME type, which results in programs refusing to open the file. (Most often text
