PHP built-in server error log location

阅读更多关于 PHP built-in server error log location

问题 I don't know if there's any? but is php built in web server also save its error logs in a file? for tailing purposes, like when creating virtual host in apache. UPDATE: i'm using mac osx 回答1: The built-in webserver doesn't log anywhere by default, so you need to provide a php.ini for it to customise this. For example, if you created a file called php.ini with this content: error_log = /Users/me/test.log log_errors = on date.timezone = UTC Then you can start PHP's built-in webserver like this:

Getting the amount of available lines in a terminal

阅读更多关于 Getting the amount of available lines in a terminal

问题 How can the amount of available lines in a terminal be found? Preferably in a cross-platform manner but any suggestions (even OS-specific) are welcome. The height and length of a terminal can be found using the os module however this does not take into account the amount of lines that may already have been used. To clarify things here is an example: In this example the height of the terminal here is 33 however since 3 lines have been used, only 30 lines are available. 回答1: Determining by that

How to use vi to edit a command in terminal on Linux?

阅读更多关于 How to use vi to edit a command in terminal on Linux?

问题 When typing a very long command, I'd like to first edit the command in a text editor(e.g. vi) then execute in case of typos.

By default, this is assigned to Ctrl-x Ctrl-e (type ctrl-x, then ctrl-e). This should open whatever editor is specified in your environment. Whatever is in the buffer when you exit

Make MIMETYPE file the first file in an EPUB ZIP file?

阅读更多关于 Make MIMETYPE file the first file in an EPUB ZIP file?

My goal is to create an EPUB file via an AppleScript, and I'm starting with semi-manually generating an EPUB file. My issue is that the IDPF EPUB validator reports that my MIMETYPE file isn't isn't the first file in my EPUB package or that my MIMETYPE doesn't exist. My AppleScript is creating the EPUB folder structure and a MIMETYPE file: set EPUBMIMETYPEfilepath to ((EPUBfolderPath & ":MIMETYPE") as string) set referenceToEPUBMIMETYPEfile to a reference to file EPUBMIMETYPEfilepath open for access referenceToEPUBMIMETYPEfile with write permission write "application/epub+zip" to

阅读更多关于 When I try to run vim in command line I get Python errors

问题 When I try running vim in the Terminal (so as to follow @romainl's suggestion in my other question) I get lots of Python errors, which all boil down to: IOError: invalid Python installation: unable to open /usr/include/python2.7/pyconfig.h (No such file or directory) Why is this? I can use Python or Sublime Text even, without any problems.

问题 I do a long pipe, that ends with ...| awk '{print $5"\t\t" $3"\t"$4}' in the Linux terminal. The columns are padded with tabs. The first column entries have different number of characters, so the second column results are not perfectly vertical.

Could not find conda environment

阅读更多关于 Could not find conda environment

I am trying to re-enter my conda environment but I am having trouble doing so as when I type conda activate (evironment name) or source activate (environment name) both return the error 'Could not find conda environment.' This is very strange as when I type conda info --envs , I get this: # conda environments: # base * /Users/(my name)/anaconda3 /anaconda3/envs/(environment name) Names and Prefixes For a Conda env to have a name it must be installed in one of the envs_dirs directories (see conda config --show envs_dirs ). Creating an env outside of one of those forfeits its "name-ability".

How do I insert a tab character in Iterm?

阅读更多关于 How do I insert a tab character in Iterm?

问题 Simply put, I know you can do ctrl + v + tab to insert a physically real tab character in a bash statement. But how do I do the same for iTerm? 回答1: The answer was to hit control+v, then tab afterwards, not all together! Hope this helps someone. 回答2: It's not iTerm, but your shell that affects how you''re able to insert a tab. First, make sure you're in BASH shell: Type the following command: $ echo $RANDOM $BASH_VERSINFO 23714 3 The first is a random number, and the second should be the BASH
