Using a filter commandEdit
Use shellescape() to escape any arguments to an external command to avoid passing possibly dangerous commands to the shell.
call setline(line('.'), getline('.') . ' ' . result)Using strftime() as explained at date or time is a better option for capturing timestamps. Ctrl R followed by = inserts the expression register, which evaluates the following expression, finishing with CR (Enter). The expression is "\t" (tab character), concatenated with the strftime() result. The final Esc exits from insert mode. The initial m' sets the previous context mark, and the final jumps to that location to restore the cursor position after the append.
The following examples capture the output of the shell's date command. To run a program, preface the shell command with ! (see For example,
If a line number is specified, the new text is inserted after that line. For example, :12read inserts the result after line 12, and :$read inserts the result after the last line. To insert the result before the first line, specify line 0 (:0read a convenience, a user command (named R) can be defined to allow easy capture of output in a scratch buffer:
:R find mtime 8 xargs grep vimIf you don't want the command output on a line by itself, or if you don't want it inserted, you can use the system() function. For example, to put the current date into a variable named curdate, which you can then use inside a script, use:
useful functions which can replace shell commands, such as strftime() or glob(), but sometimes only the shell command will do. See for a list of Vim's built in functions.
This tip shows how to capture the output from running an external (or shell) command in Vim. Vim has many Nike Sneaker 2018 Men
Use system() to capture the output of an external command in a script.
After sourcing the following script, press F8 to append the result from running the command to the current line. The date u command, which works on Unix based systems, outputs UTC time.
Using system() is the most flexible method as it allows a script to process the result before any output. For example, the function below appends the output of the command (if successfully executed) to the end of the current line. The script demonstrates these important concepts:
A filter is a program which reads text from standard input, then processes the text, and sends the result to standard output. In Vim, a range of lines can be selected, then replaced with the output from running a filter (the selected lines are the input to the filter).
Use setline() to change Nike Sneakers Shoes Low Cut text without moving the cursor.
The following example (for Unix) finds all files in or below the current directory that were modified in the last week (under 8 days); those files are searched for the text "vim", and all matching Nike Red Shoes New

let cmd = '/bin/date u ' . shellescape(format)" Append space + result to current line without moving cursor.
Append output of an external command
like systems (on Windows, use :read /t).
The results from running a shell command can be inserted into the current buffer with the :read command, or lines can be replaced in a buffer with a filter command, or Vim's system() function can be used like the backquote syntax (aka backtick) that many Unix shells provide to capture command output, which you can then use in a script or expression register ( to insert in the buffer or parse in some way.
