问题 I have a folder with a series of files named: prefix_1234_567.png prefix_abcd_efg.png I'd like to batch remove one underscore and the middle content so the output would be: prefix_567.png prefix_efg.png Relevant but not completely explanatory: How can I batch rename files using the Terminal?

问题 First off I'm using Mac. Next, I need to execute this "file.sh" we will call it. Everytime I need to execute it I have to open Terminal and type: cd /Users/Jacob/Documents/folderWithFileInIt bash file.sh This is okay, but I feel like it would be a lot quicker if I make the file execute on double click, don't you think? So my question is, how do I make this file executable via double click? My ideas were either: a) type something like chmod into terminal and change permissions? b) make a file,

问题 I'm trying to change my command promt in terminal. I keep getting the error: -bash: __git_ps1: command not found I've tried it just by typing it into the terminal as is: __git_ps1 . I've also tried it out in the .bash_profile if [ -f ~/.git-completion.bash ]; then source ~/.git-completion.bash export PS1='[\W]$(__git_ps1 "(%s)"): ' fi As you might be able to see/tell, yes, I do have the auto-completion installed and it does work great! I came across this question: " PS1 env variable does not

问题 This question already has answers here : Avoid gnome-terminal close after script execution? (7 answers) Closed 4 years ago . How do you prevent gnome-terminal from exiting after its given command has exited? I'm calling gnome-terminal from a cronjob, in order to create a terminal accessible to the user. The terminal is initially given a specific program to run. e.g. gnome-terminal --tab -e "/usr/bin/myprog" This works fine, except that when "myprog" exits, so does the gnome-terminal. How do I

问题 I would like a Java program to have different default settings (verbosity, possibly colored output where supported) depending on its use. In C, there is an isatty() function which will return 1 if a file descriptor is connected to a terminal, and 0 otherwise. Is there an equivalent for this in Java? I haven't seen anything in the JavaDoc for InputStream or PrintStream. 回答1: System.console() will return the console your application is connected to if it is connected, otherwise it returns null

问题 Killswitchcollective.com's old article, 30 June 2009, has the following inputs and outputs git co master git merge [your_branch] git push upstream A-B-C-D-E A-B-C-D-E-F-G \ ----> \ your branch C-D-E G I am interested how you get the tree like-view of commits in your terminal without using Gitk or Gitx in OS/X.

问题 I want to open a new terminal window, which will run a certain command upon opening. It preferably needs to be a real native window, and I don't mind writing different code for linux/osx/windows. I'm assuming an emulated terminal would work, as long as it supports everything a real terminal would do and isn't just printing lines of output from a command. 回答1: Opening an actual terminal window will definitely require different code for each OS. For Mac, you want something like: Runtime

问题 Okay, so I finally got myself a MacBook Air after 15 years of linux. And before I got it my big concern was UTF-8 support because no matter if I get files sent to me from windows or mac-clients theres always issues with encoding, while on ubuntu I can be sure that all output no matter what program will produce perfect utf-8 encoded data. And now on my second day (today) with OS X Im tearing my hair of by frustration. Why? When I open Nano and type some swedish characters like ÅÄÖ in it, it

问题 I'm trying to write some short script in python which would start another python code in subprocess if is not already started else terminate terminal & app (Linux).
