Tip #858   Making shell scripts executable via editor hooks

If you spend a lot of time creating new shell scripts then it can be very useful to make them executable by default. To do this in Vim add the following lines to the end of your ~/.vimrc file - creating it if necessary: 

"
" automatically give executable permissions if file begins with #! and contains
" '/bin/' in the path
"
au BufWritePost * if getline(1) =~ "^#!" | if getline(1) =~ "/bin/" | silent !chmod a+x <afile> | endif | endif


This code will automatically change the file to executable if the first line contains both "#!" and "/bin/".

Once you add #!/bin/sh (for example) to the start of a file and save it, the file will be immediately executable.
