Lc 命令 – 结合了 ls、cat 和 nano – 在没有 Home/End 键时很有用
1 分•作者: codingblink•5 个月前
这对于同时浏览目录和读取文件来说非常方便,尤其是在我的笔记本电脑上没有 Home 和 End 键的情况下。现在我不用再回到命令的开头,把 ls 改成 cat 或 nano 了。我还添加了 -e 选项,这样你就可以通过按(向上箭头键)来编辑文件,输入 '-e',然后按回车键,而无需使用 Home/End 键(如果你没有这些键)。
用法:
lc ~ : 显示主目录中的所有文件
lc ~/my-file.txt : 显示 my-file.txt 的内容
lc ~/my-file.txt -e : 使用 nano 打开 my-file.txt 进行编辑(你也可以替换成 vim 或其他编辑器)
使用方法:将以下内容添加到你的 .bashrc 文件中并刷新它
```bash
# lc 命令
lc() {
edit=false
opts=()
paths=()
for arg in "$@"; do
case "$arg" in
-e)
edit=true
;;
-*)
opts+=("$arg")
;;
*)
paths+=("$arg")
;;
esac
done
if [ ${#paths[@]} -eq 0 ]; then
ls --color=auto "${opts[@]}"
return
fi
for p in "${paths[@]}"; do
if [ -d "$p" ]; then
ls --color=auto "${opts[@]}" "$p"
elif [ -f "$p" ]; then
if $edit; then
nano "${opts[@]}" "$p"
else
cat "${opts[@]}" "$p"
fi
else
echo "lc: $p: No such file or directory" >&2
fi
done
}
```

So this kinda works well for navigating directories and reading files at the same time, especially since my laptop doesn't have home and end keys. Now I don't have to go back to the start of my command and change ls to cat or nano. I also added the -e option so you can edit the file by pressing (up arrow), type '-e', then hit enter without having to use home/end if you don't have those keys
Syntax:
lc ~ : Displays all files in the home directory
lc ~/my-file.txt : Displays the content of my-file.txt
lc ~/my-file.txt -e : opens my-file.txt for editing using nano (you can replace with vim or anything else too)<p>To use, add this to your .bashrc file and refresh it
# lc command
lc() {
edit=false
opts=()
paths=()
for arg in "$@"; do
case "$arg" in
-e)
edit=true
;;
-<i>)
opts+=("$arg")
;;
</i>)
paths+=("$arg")
;;
esac
done
if [ ${#paths[@]} -eq 0 ]; then
ls --color=auto "${opts[@]}"
return
fi
for p in "${paths[@]}"; do
if [ -d "$p" ]; then
ls --color=auto "${opts[@]}" "$p"
elif [ -f "$p" ]; then
if $edit; then
nano "${opts[@]}" "$p"
else
cat "${opts[@]}" "$p"
fi
else
echo "lc: $p: No such file or directory" >&2
fi
done
}
