osx - How to 'reset' bash to factory settings - MacOS Sierra -


i'm using macbook air 2014 , tried install python library via command line in terminal. i've tried research this, , performing commands such "bash exit" seem not work.

macbook air: mac osx sierra 10.12.3

this see in terminal when opens.

last login: sat aug 19 14:22:18 on console -bash: touch: command not found [name of computer]:~ [username]$

terminal settings: on startup, open: "new window profile, 'basic'" shells open with: 'default login shell' new windows open with: default profile, default working directory

new tabs open with: same profile, same working directory

any appreciated

tldr;

to restore terminal factory state (tested on mac os x 10.12.6 sierra), backing bash profile, history file, terminal preferences , savedstate : 

#backing mkdir ~/terminal_backup_files defaults export com.apple.terminal - > ~/terminal_backup_files/terminal_defaults.xml cp -rf ~/library/saved\ application\ state/com.apple.terminal.savedstate ~/terminal_backup_files/ cp ~/library/preferences/com.apple.terminal.plist* ~/terminal_backup_files/ cp ~/.bash* ~/terminal_backup_files/ cp -rf .bash_sessions ~/terminal_backup_files/  #restoring factory state defaults delete com.apple.terminal rm ~/library/preferences/com.apple.terminal.plist* rm -rf ~/library/saved\ application\ state/com.apple.terminal.savedstate/ rm ~/.bash_profile killall terminal

to restore how was

defaults import com.apple.terminal - < ~/terminal_backup_files/terminal_defaults.xml cp -rf ~/terminal_backup_files/com.apple.terminal.savedstate ~/library/saved\ application\ state/  cp ~/terminal_backup_files/com.apple.terminal.plist* ~/library/preferences/ cp ~/terminal_backup_files/.bash* ~/ cp -rf ~/terminal_backup_files/.bash_sessions ~/ killall terminal

original answer (inc. edit);

bash doesn't have preferences, follow directives such profiles, environment variables, , other sources , flags upon starting login session. of influenced terminal app itself.

one surefire method reset both terminal , delete user profile:

  1. delete defaults
  2. remove preference files (and preference lock files)
  3. quit terminal
  4. delete .bash_profile file.

so, if copy , paste each of these commands terminal itself, once restart it, default , standard default values repopulated relevant preference locations:

word of caution: can't undo this, , since there no privileged access involved, won't asked confirmation.

  • defaults delete com.apple.terminal
  • rm ~/library/preferences/com.apple.terminal.plist*
  • rm -rf ~/library/saved\ application\ state/com.apple.terminal.savedstate/
  • rm ~/.bash_profile
  • killall terminal

edit: backup first

mkdir ~/terminal_backup_files defaults export com.apple.terminal - > ~/terminal_backup_files/terminal_defaults.xml cp -rf ~/library/saved\ application\ state/com.apple.terminal.savedstate ~/terminal_backup_files/ cp ~/library/preferences/com.apple.terminal.plist* ~/terminal_backup_files/ cp ~/.bash* ~/terminal_backup_files/ cp -rf .bash_sessions ~/terminal_backup_files/ killall terminal reset commands above...

restoration reverse:

defaults import com.apple.terminal - < ~/terminal_backup_files/terminal_defaults.xml cp -rf ~/terminal_backup_files/com.apple.terminal.savedstate ~/library/saved\ application\ state/  cp ~/terminal_backup_files/com.apple.terminal.plist* ~/library/preferences/ cp ~/terminal_backup_files/.bash* ~/ cp -rf ~/terminal_backup_files/.bash_sessions ~/ killall terminal

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
