Vim – Create File with +x Bit Using Shell Script

chmodexecutableshell-scriptvim

Is there any way to set +x bit on script while creating?

For example I run:

vim -some_option_to_make_file_executable script.sh

and after saving I can run file without any additional movings.

ps. I can run chmod from vim or even from console itself, but this is a little annoying, cause vim suggests to reload file. Also it's annoying to type chmod command every time.
pps. It would be great to make it depending on file extension (I don't need executable .txt 🙂 )

I don't recall where I found this, but I use the following in my ~/.vimrc

" Set scripts to be executable from the shell
au BufWritePost * if getline(1) =~ "^#!" | if getline(1) =~ "/bin/" | silent !chmod +x <afile> | endif | endif

The command automatically sets the executable bit if the first line starts with "#!" or contains "/bin/".

Vim keybinding to delete up to (but not including) the next period

Btw, if you want to delete a sentence you can use the sentence forward motion like this:

d)i.

Meaning, deleting the sentence including the period and then inserting it again.

d/\. is necessary, if you want to delete multiple lines and there is a non-text document context, e.g. empty lines in between text and you really want to delete to the next period.

If the period is on the same line, you can just use the till-before motion: dt.

Typing

:normal d/\.^M

(Ctrl+V + Enter at the end)

works for me.

But I have to say that I don't understand the need for :normal.

I mean, using

:map <F10> d/\.<CR>:noh<CR>

the search starts at the position where the cursor is located and ends at the next period.

Trailing spaces when copying from console

You'll have spaces at the end of the line when selecting and copying from the terminal if the application displayed spaces at that spot. Applications may display spaces in order to erase what was there before. Terminals have commands to delete a whole line or delete characters to the right of the cursor; applications choose between that and displaying spaces based on what they consider most efficient. For example, if you type some stuff at a prompt, then press Backspace, the application (e.g. the shell) is likely to overwrite the last character with a space.

If you have an X11 connection, you can use xsel or xclip to copy a file to the local clipboard.

Experimentally, Vim seems to go through pains not to display lines ending with spaces (even when the buffer contains a line that ends with spaces). So copying from that is an option if you don't have an X11 connection.

An alternative would be to post-process after copying:

xsel | sed 's/  *$//' | xsel
