Script Template in vim

Script templates in Vim

Every time I wrote Bash or Python scripts in Vim, I had to add the Shebang #! /bin/bash or #! /usr/bin/python in the scripts manually.

So how can we automate this process with Vim to catch *.sh or *.py extensions and create a new file with our desired template, Let’s go for it :

First, you need to create a template file at $HOME/.vim/sh_template.temp with the contents you want:

#! /bin/bash # ================================================================= # Author: < Your Name > # Email: <Your Email> # Script Name: # Date Created: # Last Modified: # Description: # < Description of what is this script for > # Usage: # < How to use this script , flag usage or ... > # ================================================================= # ======================== Start Of Code ========================== set -xe 

Next, you need to configure autocmd in Vim by editing $HOME/.vimrc and adding this line:

" ========= Shell Script Template ======================== au bufnewfile *.sh 0r $HOME/.vim/sh_template.temp 

Note:

• Comment lines in vim scripting that are applied in .vimrc too, begin with " character .
• au represents autocmd. autocmd docs
• bufnewfile event for opening a file that doesn’t exist for editing.
• *.sh cath all files with .sh extension. For Python scripts, you can replace it with *.py .

Now its time to create a shell script with the desired template:

vi Shell_Script.sh

• You can follow the same steps for every script or language you need.
