问题 I want to set the environment variable I added below the line to ~/.bash_profile and ~/.profile but it didn't work. export JBOSS_HOME=/Users/{USERNAME}/Desktop/jboss7 Afterward, exit the terminal and open it again when executing echo $JBOSS_HOME I get nothing. 回答1: Apple has changed the default shell to zsh. Therefore you have to rename your configuration files. .bashrc is now .zshrc and .bash_profile is now .zprofile . 回答2: I created a new file called /usr/local/bin/mybash which contains a

export function from zsh to bash for use in gnu parallel

问题 How do I export a function from zsh, so that I can use it in gnu parallel? example: function my_func(){ echo $1;} export -f my_func parallel "my_func {}" ::: 1 2 in bash will output 1 2 whereas in zsh it will output error messages /bin/bash: my_func: command not found /bin/bash: my_func: command not found 回答1: zsh does not have a concept of exporting functions. export -f somefunc will print the function definition, it will not export a function. Instead, you can rely on the fact that bash

问题 I want to install this ZSH theme . I downloaded both the iTerm2 and ZSH themes. The iTerm theme was imported through the preferences. The ZSH theme was inserted into ~/.oh-my-zsh/themes along with all the other ZSH themes. When I open my .zshrc and change ZSH_THEME="bobbyrussell" to ZSH_THEME="cobalt2" nothing happens. I restart iTerm but the colors are not changed. Updated with Details: ~ echo $ZSH_THEME cobalt2 ~ echo $PROMPT %/ ~ File: ~/.zshrc # Path to your oh-my-zsh installation. export

由 本秂侑毒 提交于 2019-12-08 04:37:30
问题 Background : I installed shell integration in iTerm2 and enabled saving all command history to disk so it persists between sessions (Preferences > General > Save copy/paste and command history to disk). Questions : A) Is there is a limit to how much history will be stored? Does it follow the value assigned to the HISTFILESIZE environment variable, or is it controlled some other way, or limited by default? B) The history in the toolbelt contains additional information like the working

Recursively search directory of binary files for hexadecimal sequence?

由 故事扮演 提交于 2019-12-07 16:31:17
问题 The current commands I'm using to search some hex values (say 0A 8b 02 ) involve: find . -type f -not -name "*.png" -exec xxd -p {} \; | grep "0a8b02" || xargs -0 -P 4 Is it possible to improve this given the following goals: search files recursively display the offset and filename exclude certain files with certain extensions (above example will not search .png files) speed: search needs to handle 200,000 files (around 50KB to 1MB) in a directly totaling ~2GB. I'm not too confident if the
