oh-my-zsh出现的问题

由于之前的VPS到期了，又买了台VPS，想打造成高逼格的开发环境，结果在装上oh-my-zsh后，.zshrc配置如下：

ZSH_CUSTOM=/home/sean/.oh-my-zsh/custom

plugins=(
  git
  git-extras
  autojump
  zsh-syntax-highlighting
  zsh-autosuggestions
  osx
  extract
  dirhistory
)

[[ -s /home/sean/.autojump/etc/profile.d/autojump.sh ]] && source /home/sean/.autojump/etc/profile.d/autojump.sh
source $ZSH_CUSTOM/plugins/zsh-autosuggestions/zsh-autosuggestions.zsh
source $ZSH_CUSTOM/plugins/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

ZSH_CUSTOM=/home/sean/.oh-my-zsh/custom

plugins=(

git

git-extras

autojump

zsh-syntax-highlighting

zsh-autosuggestions

osx

extract

dirhistory

)

[[ -s /home/sean/.autojump/etc/profile.d/autojump.sh ]] && source /home/sean/.autojump/etc/profile.d/autojump.sh

source $ZSH_CUSTOM/plugins/zsh-autosuggestions/zsh-autosuggestions.zsh

source $ZSH_CUSTOM/plugins/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

装了几个插件后，就出现了各种报错，如下只粘了一条，各种命令找不到：

/home/user/.oh-my-zsh/plugins/git/git.plugin.zsh:170: command not found: compdef

1	/home/user/.oh-my-zsh/plugins/git/git.plugin.zsh:170: command not found: compdef

根据经验，应该是PATH设置得不对，但是无论怎么设置，就是不行。后来各种google，终于找到了解决办法：

chmod a-r /etc/profile.d/autojump.sh

1	chmod a-r /etc/profile.d/autojump.sh

一大堆报错没了，但又有了新报错：

/etc/bashrc:37: command not found: shopt
omz_history:fc:13: no such event: 1
/etc/bashrc:40: command not found: shopt
/etc/bashrc:51: command not found: shopt

/etc/bashrc:37: command not found: shopt

omz_history:fc:13: no such event: 1

/etc/bashrc:40: command not found: shopt

/etc/bashrc:51: command not found: shopt

shopt报错的原因为：

shopt is not a command, but a shell built-in. You can find out this by running the following command in bash：

type shopt
output would be:

shopt is a shell builtin

shopt is not a command, but a shell built-in. You can find out this by running the following command in bash：

type shopt

output would be:

shopt is a shell builtin

解决方法：

solution:
step1:
printf "#!/bin/bash\n\nshopt \$*\n" > /usr/local/bin/shopt
then you will get /usr/local/bin/shopt:

#!/bin/bash
shopt $*

step2:
chmod +x /usr/local/bin/shopt

step3:
ln -s /usr/local/bin/shopt /usr/bin/shopt

step4:
echo "alias shopt='/usr/bin/shopt'" >> ~/.zshrc

solution:

step1:

printf "#!/bin/bash\n\nshopt \$*\n" > /usr/local/bin/shopt

then you will get /usr/local/bin/shopt:

#!/bin/bash

shopt $*

step2:

chmod +x /usr/local/bin/shopt

step3:

ln -s /usr/local/bin/shopt /usr/bin/shopt

step4:

echo "alias shopt='/usr/bin/shopt'" >> ~/.zshrc

其中升级zsh命令为：

upgrade_oh_my_zsh

1	upgrade_oh_my_zsh

2019-05-21: 今天发现, 上下方向键不能搜索命令历史了, 后来统一在如下文件里定义(可以放到~/.oh-my-zsh/lib/key-bindings.zsh , 但是为了好管理, 还是统一放到.zshrc里):

[~]$ tail -n30  ~/.zshrc

shell脚本输出带文本颜色背景颜色自定义样式格式内容

shell脚本中 echo 和 printf 都可以输出内容。示例1：

echo -e "\033[43;35m david use echo say Hello World \033[0m \n" 

printf "\033[44;36m david use printf say Hello World \033[0m \n" 

echo -e "\033[47;30;5m david use echo say \033[0m Hello World \n"

echo -e "\033[43;35m david use echo say Hello World \033[0m \n"

printf "\033[44;36m david use printf say Hello World \033[0m \n"

echo -e "\033[47;30;5m david use echo say \033[0m Hello World \n"

它的格式是这样的：

echo -e "\033[字背景颜色;字体颜色m 字符串 \033[0m"  或者
printf "\033[字背景颜色;字体颜色m 字符串 \033[0m"  或者
echo -e "\033[字背景颜色;字体颜色m;ascii码m 字符串 \033[0m 字符串(can null) \n"

echo -e "\033[字背景颜色;字体颜色m 字符串 \033[0m" 或者

printf "\033[字背景颜色;字体颜色m 字符串 \033[0m" 或者

echo -e "\033[字背景颜色;字体颜色m;ascii码m 字符串 \033[0m 字符串(can null) \n"

格式说明 shell脚本中echo命令是内容显示，echo显示带颜色需要使用参数 -e 格式如下： echo -e “\033[字背景颜色；文字颜色m字符串\033[0m” 例如： echo -e “\033[41;36m something here \033[0m” 其中41的位置代表底色， 36的位置是代表字的颜色注： 1、字背景颜色和文字颜色之间是英文的”;” 2、文字颜色后面有个m 3、字符串前后可以没有空格，如果有的话，输出也是同样有空格特效可以叠加，需要使用“;”隔开，例如：闪烁+下划线+白底色+黑字为 \033[5;4;47;30m闪烁+下划线+白底色+黑字为\033[0m 再来看示例1的第3个命令：

echo -e "\033[47;30;5m david use echo say \033[0m Hello World \n"

1	echo -e "\033[47;30;5m david use echo say \033[0m Hello World \n"

这个命令解释: 47 代表背景色为白色， 30 代表字体为黑色， 5 代表字体闪烁， 0 代表关闭所有属性输出字符 “david use echo say”，然后重新设置屏幕到缺省设置，输出字符 “Hello World”后颜色回复正常。 -e是echo的一个可选项，用于激活特殊字符的解析器, Read more…

2023-10-10更新：用tput sgr0进行属性还原时，在web页面输出会显示出一个(B符号，如下：参考https://github.com/rburns/ansi-to-html/issues/25 解决方法是，增加一个变量：TERM=ansi 整体脚本如下：
