Depending on what you want the file to contain:
根据您希望文件包含的内容:
touch /path/to/filefor an empty filesomecommand > /path/to/filefor a file containing the output of some command.eg: grep --help > randomtext.txt echo "This is some text" > randomtext.txtnano /path/to/fileorvi /path/to/file(orany other editor emacs,gedit etc)
It either opens the existing one for editing or creates & opens the empty file to enter, if it doesn't exist
touch /path/to/file对于空文件somecommand > /path/to/file对于包含某些命令输出的文件。eg: grep --help > randomtext.txt echo "This is some text" > randomtext.txtnano /path/to/file或vi /path/to/file(或any other editor emacs,gedit etc)
它要么打开现有文件进行编辑,要么创建并打开空文件以输入(如果它不存在)

Create the file using cat
使用创建文件 cat
$ cat > myfile.txt
$ cat > myfile.txt
Now, just type whatever you want in the file:
现在,只需在文件中输入您想要的任何内容:

There are several possible solutions:
有几种可能的解决方案:
Create an empty file
创建一个空文件
touch file
>file
echo -n > file
printf '' > file
The echoversion will work only if your version of echosupports the -nswitch to suppress newlines. This is a non-standard addition. The other examples will all work in a POSIX shell.
echo仅当您的版本echo支持-n禁止换行的开关时,该版本才有效。这是一个非标准的添加。其他示例都将在 POSIX shell 中工作。
Create a file containing a newline and nothing else
创建一个包含换行符而没有其他内容的文件
echo '' > file
printf '\n' > file
This is a valid "text file" because it ends in a newline.
这是一个有效的“文本文件”,因为它以换行符结尾。
Write text into a file
将文本写入文件
"$EDITOR" file
echo 'text' > file
cat > file <<END \
text
END
printf 'text\n' > file
These are equivalent. The $EDITORcommand assumes that you have an interactive text editor defined in the EDITOR environment variable and that you interactively enter equivalent text. The catversion presumes a literal newline after the \and after each other line. Other than that these will all work in a POSIX shell.
这些是等价的。该$EDITOR命令假定您在 EDITOR 环境变量中定义了一个交互式文本编辑器,并且您以交互方式输入等效文本。该cat版本假定\在每一行之后和之后都有一个文字换行符。除此之外,这些都可以在 POSIX shell 中工作。
Of course there are many other methods of writing and creating files, too.
当然,还有许多其他的写入和创建文件的方法。

In case you guys are trying to create a new file, but it says: 'File does not exist', it's simply because you are also accessing a directory, which does not exist yet. You have to create all non existent directories first, using the mkdir /path/to/dircommand.
如果你们正在尝试创建一个新文件,但它说:'File does not exist',这仅仅是因为您也在访问一个尚不存在的目录。您必须首先使用该mkdir /path/to/dir命令创建所有不存在的目录。

This will create an empty file with the current timestamp
这将创建一个带有当前时间戳的空文件
touch filename
