linux vi不显示光标的解决办法:1、登录linux系统,进入终端;2、通过执行“echo -e "\033[?25h"”方法显示光标即可。

Linux终端光标消失问题

今天在用vim写脚本的时候,突然间发现光标消失了,这就很难受了,不知道编辑位置在哪。

一开始一直在找vim的配置问题,但是后来发现终端的光标也消失了。

这才知道终端的光标和vim的光标是关联的,所以只需要把终端的光标搞出来就行了。

隐藏光标

echo -e "\033[?25l"

显示光标

echo -e "\033[?25h"

相关拓展:

在Linux终端中,你可以快速移动光标、进行命令编辑、执行编辑中的历史命令、使用Bang(!)命令和控制命令。让basher更有效率。

一、说明

Ctrl – k: 先按住 Ctrl 键,然后再按 k 键;

Alt – k: 先按住 Alt 键,然后再按 k 键;

M – k:先单击 Esc 键,然后再按 k 键。

二、移动光标

Ctrl – a :移到行首

Ctrl – e :移到行尾

Ctrl – b :往回(左)移动一个字符

Ctrl – f :往后(右)移动一个字符

Alt – b :往回(左)移动一个单词

Alt – f :往后(右)移动一个单词

Ctrl – xx :在命令行尾和光标之间移动

M-b :往回(左)移动一个单词

M-f :往后(右)移动一个单词

三、编辑命令

Ctrl – h :删除光标左方位置的字符

Ctrl – d :删除光标右方位置的字符(注意:当前命令行没有任何字符时,会注销系统或结束终端)

Ctrl – w :由光标位置开始,往左删除单词。往行首删

Alt – d :由光标位置开始,往右删除单词。往行尾删

M – d :由光标位置开始,删除单词,直到该单词结束。

Ctrl – k :由光标所在位置开始,删除右方所有的字符,直到该行结束。

Ctrl – u :由光标所在位置开始,删除左方所有的字符,直到该行开始。

Ctrl – y :粘贴之前删除的内容到光标后。

Alt + t :交换光标处和之前两个字符的位置。

Alt + . :使用上一条命令的最后一个参数。

Ctrl – _ :回复之前的状态。撤销操作。

Ctrl -a + Ctrl -k 或 Ctrl -e + Ctrl -u 或 Ctrl -k + Ctrl -u 组合可删除整行。

四、Bang(!)命令

!! :执行上一条命令。

foobar :把上一条命令里的foo替换为bar,并执行。

!wget :执行最近的以wget开头的命令。

!wget:p :仅打印最近的以wget开头的命令,不执行。

!$ :上一条命令的最后一个参数, 与 Alt - . 和 $_ 相同。

!* :上一条命令的所有参数

!*:p :打印上一条命令是所有参数,也即 !*的内容。

^abc :删除上一条命令中的abc。

foobar :将上一条命令中的 foo 替换为 bar

foobar^ :将上一条命令中的 foo 替换为 bar

!-n :执行前n条命令,执行上一条命令: !-1, 执行前5条命令的格式是: !-5

五、查找历史命令

Ctrl – p :显示当前命令的上一条历史命令

Ctrl – n :显示当前命令的下一条历史命令

Ctrl – r :搜索历史命令,随着输入会显示历史命令中的一条匹配命令,Enter键执行匹配命令;ESC键在命令行显示而不执行匹配命令。

Ctrl – g :从历史搜索模式(Ctrl – r)退出。

六、控制命令

Ctrl – l :清除屏幕,然后,在最上面重新显示目前光标所在的这一行的内容。

Ctrl – o :执行当前命令,并选择上一条命令。

Ctrl – s :阻止屏幕输出

Ctrl – q :允许屏幕输出

Ctrl – c :终止命令

Ctrl – z :挂起命令

七、重复执行操作动作

M – 操作次数 操作动作 : 指定操作次数,重复执行指定的操作。
