问题 I have a number of compressed archives with the extension .tar.xz . I am advised that, when decompressed, the total size required is around 2TB. Within the archives are a number of images that I am solely after. Is there a method to solely extract files for example with the extensions .jpeg, .jpeg and .gif from the compressed archives without having to extract every file? Thanks 回答1: It's trivial to just extract one of the file types; for example: tar -xjf archive.tar.xz '*.jpeg' will extract

问题 I have tried many times to initialise conda for shell interaction using the command "conda init bash" on my terminal but it always says "No action taken." What am I doing wrong? 回答1: With so little details in your question it's hard to help you. You should read carefully and paste what conda init bash is outputting (and your .bashrc , .bash_profile and output of PATH ). I was in a similar issue and what happened was that the conda init modifies your .bash_profile and adds some code at the end

问题 I have the following line that I run in terminal: say "hello, this is the computer talking" --interactive When I run this command, the computer speaks the words in quotes and highlights the words as they are spoken. What I would like to do is get the time of each spoken word. For example: 00.00 hello 01.23 this 01.78 is 02.10 the 02.70 computer 03.30 talking I am wondering if there is any way to write a bash script that would interact with the output of the line. 回答1: Here is a Zsh script

问题 I have and Ubuntu 14.04 ec2 instance with my scripts uploaded there. When I want to run a script remotely using my mac's terminal I do ssh myaws "python MyFolder/myscript.py" which runs perfectly. However, I want the script to run on ec2 even after I close the terminal window on my mac or switch off my mac. Once I figure that out I will move onto using cron to schedule my scripts to run on ec2 without me ever ssh-ing in. Is it possible and if it is how would I go about it? Let me now if you

问题 I recently installed GNU Octave on my Mac using Homebrew and as soon as I typed octave into bash, it opened up the octave-gui window. The Octave GUI looks quite unappealing (on a mac, at least) so I wanted to use the command line interface. My fix was to create a permanent alias in ~/.bash_profile which was alias octave='octave --no-gui' . Is there a more permanent fix to this? That is, how can I start using octave without invoking the GUI instead of the CLI? Is there a solution where I don't
