email address to system user

Email address to user

My goal is to build a bash script to which I give "mihamina@rktmb.org" and "password" as argument, and then it creates a system user named "mihamina-rktmb-org".

The discribed method requires you to install the package "whois", containing "mkpasswd". Dont ask me why.

At the same time, the script will insert an alias entry into an alias flat file. For "mihamina@rktmb.org", it will insert

 mihamina: mihamina-rktmb-org 
in "/etc/exim4/virtual/rktmb.org".

The BASH script

 #!/bin/bash EMAIL=$1 PASS=$2 EXIM_VIRT_DIR="/etc/exim4/virtual/" DOMAINE=$(echo ${EMAIL} | awk -F"@" '{print $2}') LOCALPART=$(echo ${EMAIL} | awk -F"@" '{print $1}') U=$(echo ${EMAIL} | sed 's/\./-/g' | sed 's/@/-/g') CRYPT1_PASS=$(mkpasswd ${PASS}) echo ${EMAIL} echo ${PASS} echo ${DOMAINE} echo ${LOCALPART} echo ${CRYPT1_PASS} echo ${U} useradd  \ --home-dir /home/${U} \ --create-home  \ --password ${CRYPT1_PASS} \ --shell "/bin/bash" ${U} echo "${LOCALPART}:  ${U}" >> ${EXIM_VIRT_DIR}${DOMAINE} invoke-rc.d exim4 restart

npm run build base-href

Using NPM to specify base-href When building an Angular application, people usually use "ng" and pass arguments to that invocation. Typically, when wanting to hard code "base-href" in "index.html", one will issue: ng build --base-href='https://ngx.rktmb.org/foo' I used to build my angular apps through Bamboo or Jenkins and they have a "npm" plugin. I got the habit to build the application with "npm run build" before deploying it. But the development team once asked me to set the "--base-href='https://ngx.rktmb.org/foo'" parameter. npm run build --base-href='https://ngx.rktmb.org/foo did not set the base href in indext.html After looking for a while, I found https://github.com/angular/angular-cli/issues/13560 where it says: You need to use −− to pass arguments to npm scripts. This did the job! The command to issue is then: npm run build -- --base-href='https://ngx.rktmb.org/foo&

emacs29 intelephense

Emacs 29 and PHP Intelephense I use to use Emacs and PHP Intelephense for PHP development. I recently upgraded to Emacs 29 and PHP Intelephense stopped working. I found a solution on Reddit Based on that, I rewrote my .emacs file to use eglot instead of lsp-mode, and this is the result. (use-package eglot :ensure t) (add-hook 'php-mode-hook 'eglot-ensure) (use-package php-mode :ensure t :mode ("\\.php\\'" . php-mode)) (add-to-list 'auto-mode-alist '("\\.php$" . php-mode)) (provide 'lang-php) (use-package company :ensure t :config (setq company-idle-delay 0.3) (global-company-mode 1) (global-set-key (kbd "M- ") 'company-complete)) (require 'eglot) (add-to-list 'eglot-server-programs '((php-mode :language-id "php") .
